NVIDIA's high-TDP flagship GPU, the GeForce RTX 5090, appears to cause additional headaches for users, not including the high power bill. According to a Reddit user, we now have the first documented case of a melted power connector on NVIDIA's flagship GeForce RTX 5090 Founders Edition, reigniting concerns over high-wattage GPU safety from the last generation. While playing Battlefield 5, Reddit user ivan6953 detected a burning odor and immediately shut down their system, only to discover severe damage to both the RTX 5090's 12V-2×6 connector and their ASUS ROG Loki SFX-L PSU. The user had employed a Moddiy 12VHPWR cable, marketed as ATX 3.0/PCIe 5.0-compliant and rated for RTX 5090's 600 watts of power. Despite claims of secure installation—audible clicks at both ends—the cable melted at 500-520 W load, charring connectors on the GPU and PSU.

Notably, the same cable had powered an RTX 4090 FE for two years without issue. NVIDIA's RTX 5090 FE ships with a redesigned adapter featuring a longer, more flexible cable and an angled connector to reduce strain in compact builds. NVIDIA asserts that no incidents have occurred with its bundled adapter, emphasizing compliance with the updated 12V-2×6 standard, which shortens sensing pins to prevent power flow if connections loosen. Hence, an older connector can not provide 100% secure usage despite the user thinking that the sensing pins are touching properly.

The GPU market is heating this March as both NVIDIA and AMD prepare to launch competing mid-range graphics cards. NVIDIA's GeForce RTX 5060 and RTX 5060 Ti, part of its Blackwell architecture lineup, are rumored to debut alongside AMD's Radeon RX 9070 and 9070 XT, setting the stage for a high-stakes battle in the mainstream gaming segment. According to leaks from Chinese hardware sources at Douyin, including ZOTAC-affiliated leakers, the RTX 5060 series will retain traditional 8-pin power connectors instead of adopting NVIDIA's newer 12V-2x6 16-pin design, simplifying upgrades for users with older PSUs.

However, the cards will reportedly require a minimum 650 W power supply—a 100 W increase over the RTX 4060 series—with estimated total graphics power (TGP) of 150 W for the RTX 5060 and 200 W for the Ti variant. While NVIDIA has not confirmed specifications, the RTX 5060 Ti will reportedly launch in two variants: 8 GB and 16 GB GDDR7 configurations, leveraging a 128-bit bus.

During a recent press event in South Korea, NVIDIA addressed concerns about power connector safety for their upcoming RTX 5090 graphics card. The new GPU will consume 575 watts of power, marking a massive 225-watt increase from its predecessor, the RTX 4090. The previous generation RTX 4090 faced significant issues with melting 12VHPWR power connectors, especially with third-party adapters, where incomplete connections led to overheating and connector damage. When questioned about potential risks with the RTX 5090's higher power draw, NVIDIA representatives stated they've implemented an updated 12V-2×6 power connector across the RTX 50 series. Unlike the 12VHPWR 16-pin connector, the new 12V-2x6 has sense pins having recessed further back to ensure proper contact before the GPU can request higher power outputs.

"It is expected that such issues will not occur with the RTX 50 series," a company representative explained during the Q&A session. "After about two years, we believe these problems have been resolved." While the company maintains that user error was the leading cause of failures, the extended timeframe required for developing and shipping revised connectors raised questions about the initial design's reliability. Despite NVIDIA's assurances, the RTX 5090's exceptional power requirements could potentially amplify any unexpected technical issues. The company's previous experience showed that problems became more pronounced in cards with higher power demands, as demonstrated by the RTX 4090 having more incidents than the lower-powered RTX 4080 series. So, more power means more trouble, but the company has worked on it to ensure no future problems arise.

Details of ASUS' next generation BTF 2.0 (BTF stands for Back to the Future) platform have appeared online, courtesy of Andreas Schilling from HardwareLuxx. The editor posted pictures from an ASUS presentation over at Bluesky that details one major change to the power connector design, which will make the BTF 2.0 graphics cards compatible with non BTF systems. This suggests that ASUS might consider offering more graphics cards with BTF 2.0 support, since they can be used in any system with the proposed changes.

As you may or may not know, the first generation BTF graphics cards ended up with a power connector at the rear, bottom edge of the graphics cards, placed somewhat behind the PCIe gold fingers. The cards also lacked any other power connectors, which made them exclusive for BTF builds. To solve this conundrum, ASUS moved its GC-HPWR PCB power connector up on the PCB, making sure it clears any motherboard components. However, instead of increasing the height of the motherboard BTF 2.0 connector, the company provides a small adapter that plugs in between the motherboard and graphics card, to make its new BTF 2.0 cards compatible with any system.

At the 2025 International CES, ASUS showed off its Radeon RX 9070 XT TUF Gaming graphics card. This card was part of a multi-brand showcase AMD set up in its booth. The card features the latest generation of TUF Gaming board design that the company is debuting with the GeForce RTX 50-series and Radeon RX 90-series. The card features a triple slot cooling solution, with its Axial-Tech fans taking up an entire slot (thicker fans mean lower RPM). The PCB is 2/3 the length of the card, so all airflow from the third fan is vented through the heatsink and out a large cutout on the backplate.

Perhaps the most striking feature of the ASUS TUF Gaming RX 9070 XT is its power connectors. The card calls for three 8-pin PCIe power connectors. We've only seen one other custom RX 9070 XT come with three connectors, and that is the XFX RX 9070 XT Merc 319 Black. The question then arises, what is a small performance-segment GPU going to do with 525 W of power on tap? Most other cards, including the PowerColor Red Devil, come with just two 8-pin connectors (375 W), so does the presence of three connectors mean that the board power of overclocked RX 7090 XT exceed 300 W, and board partners are trying to reduce the load on the 75 W put out by the PCIe slot, by sneaking in a third 8-pin input? This isn't the only oddball power connector configuration we've seen at CES for the RX 9070 series. The ASRock RX 9070 XT Taichi comes with a 16-pin 12V2x6 power connector, although there's no way of telling yet if this is configured for 600 W—it could even be keyed for 300 W.

ASUS extended its line of motherboards at CES 2025, featuring a design that moves power connectors to the back of the board. The company calls this approach "BTF" (Back To Future), aiming to improve cable management in PC builds. The TUF GAMING B850-BTF WIFI and B860-PLUS WIFI models demonstrate this new design, which can deliver up to 600 watts through the motherboard to support modern graphics cards. The boards include Wi-Fi 7 connectivity, PCIe 5.0 support, and multiple M.2 slots for storage devices. In the high-end segment, ASUS presented the ROG Maximus Z890 HERO BTF, compatible with Intel's LGA1851 processors. This board features DDR5 memory support, dual Thunderbolt 4 ports, and tools like Q-Release for easier graphics card removal.

For professional users, ASUS released the ProArt Z890 CREATOR WIFI, equipped with Thunderbolt 4 ports and specialized cooling systems. The company also showed new gaming-focused models including the ROG Crosshair X870E APEX, for the fastest Ryzen 9000X3D series gaming processors. The motherboards share several technical features across different price points. All models support PCIe 5.0 for graphics cards and storage, while most include Wi-Fi 7 capabilities. ASUS has added tool-free installation mechanisms for M.2 drives across the lineup. ASUS has not yet announced pricing or specific release dates for the new motherboards. The BTF design represents a significant change in motherboard layout, though it will require compatible PC cases and power supplies to function as intended. This marks one of the first major changes to standard motherboard design since the ATX format became common in the 1990s.

AMD will continue using traditional PCI Express power connectors for its upcoming Radeon RX 9000 series RDNA 4 graphics cards, according to recent information shared on the Chiphell forum. While there were some expectations that AMD would mimic NVIDIA's approach, which requires the newer 16-pin 12V-2×6 connector for its GeForce RTX 50 series, the latest information suggests a more traditional power approach. While AMD plans to release its next generation of graphics cards in the first quarter, most technical details remain unknown. The company's choice to stick with standard power connectors follows the pattern set by their recent Radeon RX 7900 GRE, which demonstrated that conventional PCI Express connectors can adequately handle power demands up to 375 W. The standard connectors eliminate the need for adapters, a feature AMD could highlight as an advantage. An earlier leak suggested that the Radeon RX 9070 XT can draw up to 330 W of power at peak load.

Intel reportedly cited similar reasons for using standard power connectors in their Arc "Battlemage" graphics cards, suggesting broader industry support for maintaining existing connection standards. NVIDIA's different approach reportedly requires all board partners to use the 12V-2×6 connector for the RTX 50 series, removing the option for traditional PCI Express power connectors. In contrast, AMD's decision gives its manufacturing partners more flexibility in their design choices, and MBA (Made by AMD) reference cards don't enforce the new 12V-2×6 power connector standard. Beyond the power connector details and general release timeframe pointing to CES, AMD has revealed little about the RDNA 4 architecture's capabilities. Only the reference card's physical appearance and naming scheme appear to be finalized, leaving questions about performance specifications unanswered, as early underwhelming performance leaks are somewhat unreliable until final drivers and final optimizations land.

NVIDIA CEO Jensen Huang never misses an opportunity to remind us that Moore's Law is cooked, and that future generations of logic hardware will only get larger and hotter, or hungrier for power. NVIDIA's next generation "Blackwell" graphics architecture promises to bring certain architecture-level performance/Watt improvements, coupled with the node-level performance/Watt improvements from the switch to the TSMC 4NP (4 nm-class) node. Even so, the GeForce RTX 5090, or the part that succeeds the current RTX 4090, will be a power hungry GPU, with rumors suggesting the need for two 16-pin power inputs.

TweakTown reports that the RTX 5090 could come with two 16-pin power connectors, which should give the card the theoretical ability to pull 1200 W (continuous). This doesn't mean that the GPU's total graphics power (TGP) is 1200 W, but a number close to or greater than 600 W, which calls for two of these connectors. Even if the TGP is exactly 600 W, NVIDIA would want to deploy two inputs, to spread the load among two connectors, and improve physical resilience of the connector. It's likely that both connectors will have 600 W input capability, so end-users don't mix up connectors should one of them be 600 W and the other keyed to 150 W or 300 W.

MSI is thrilled to introduce a groundbreaking feature on its X870(E) series motherboards. This innovative is designed with gamers and professionals in mind, provides the extra power required for AI computing and GPU-intensive applications. The supplemental PCIe Power feature, equipped with an integrated 8-pin PCIe power connector, delivers additional power for GPUs demanding higher wattage, ensuring they can achieve their peak performance. Paired with the ATX 3.1 power standard, which can hold up to a 2.5x power excursion for enhanced reliability and better power delivery, this feature ensures stable, efficient, and sustained performance, even under heavy loads. Whether gaming or tackling complex applications, this supplemental PCIe Power offers unmatched reliability and stability for the most demanding environments.

What is Supplemental PCIe Power?
Think of it as an extra battery pack for your motherboard. The system's 12 V power on the 24pin power connector from the motherboard basically handles all the PCIe interface, fans and RGB extensions. Still, the supplemental PCIe power ensures everything runs smoothly when your PC is pushed to the limit—like when running very intensive graphical games or maximizing all the fan dissipation for extreme performance.

NVIDIA is reportedly looking to change the power connector standard for the fourth successive time in a span of three years, with its upcoming GeForce RTX 50-series "Blackwell" GPUs, Moore's Law is Dead reports. NVIDIA began its post 8-pin PCIe journey with the 12-pin Molex MicroFit connector for the GeForce RTX 3080 and RTX 3090 Founders Edition cards. The RTX 3090 Ti would go on to standardize the 12VHPWR connector, which the company would debut across a wider section of its GeForce RTX 40-series "Ada" product stack (all SKUs with TGP of over 200 W). In the face of rising complains of the reliability of 12VHPWR, some partner RTX 40-series cards are beginning to implement the pin-compatible but sturdier 12V-2x6. The implementation of the 16-pin PCIe Gen 6 connector would be the fourth power connector change, if the rumors are true. A different source says that rival AMD has no plans to change from the classic 8-pin PCIe power connectors.

Update 15:48 UTC: Our friends at Hardware Busters have reliable sources in the power supply industry with equal access to the PCIe CEM specification as NVIDIA, and say that the story of NVIDIA adopting a new power connector with "Blackwell" is likely false. NVIDIA is expected to debut the new GPU series toward the end of 2024, and if a new power connector was in the offing, by now the power supply industry would have some clue. It doesn't. Read more about this in the Hardware Busters article in the source link below.

Update Feb 20th: In an earlier version of the article, it was incorrectly reported that the "16-pin connector" is fundamentally different from the current 12V-2x6, with 16 pins dedicated to power delivery. We have since been corrected by Moore's Law is Dead, that it is in fact the same 12V-2x6, but with an updated PCIe 6.0 CEM specification.

Twitter/X user @momomo_us has unveiled official documentation detailing a new GC-HPCE power connection standard to supply additional GPU power throughout motherboard. This connector can deliver over 600 Watts of power, surpassing 12VHPWR connector's capacity. The GC-HPCE power connector features four groups of pins. Sixteen pins are dedicated to power delivery, while the remaining twelve facilitate communication between the motherboard and the graphics card. Its size is comparable to the regular PCIe x1 connector. Positioned in alignment with the primary PCIe x16 slot on a motherboard, the GC-HPCE power connector is situated behind the x16 slot, typically where the motherboard chipset heatsink is found. This strategic placement ensures the graphics card can be easily slotted into both connectors, simplifying installation. The connector's design negates the need for an additional locking mechanism, as the x16 slot's existing lock sufficiently secures the graphics card.

First showcased at Computex, this connector was featured in several prototype motherboards and graphics cards, emphasizing its potential to enhance cable management and aesthetics. By eliminating supplementary power cables from the graphics card and channeling power through the motherboard, the graphics card's appearance remains uncluttered, and cable management behind the motherboard tray becomes more streamlined. Intriguingly, this connector is a familiar design. It's a modified version of the High Power Card Edge (HPCE) standard prevalent in the server industry. While ASUS has been the primary proponent of this connector, it remains to be seen if other companies will adopt this standard for their consumer products. Additionally, routing power throughout the motherboard will require manufacturers to include additional power regulating circuitry, potentially driving motherboard costs up. It is also not an agreed upon industry standard, which could block some future GPU upgrades from happening.You can check out ASUS'es implementation of the Back-to-Future (BTF) motherboard that supports this connector below.

We witnessed an exciting concept during the Computex 2023 show in late May. ASUS has developed a GPU without an external power connector called GC_HPWR. Unlike current solutions, this connection type doesn't require additional cables. Using the GC_HPWR means that power is being supplied directly from the motherboard and that these special-edition GPUs also require special-edition motherboards. Thanks to the latest information from the Bilibili content creator Eixa Studio, attending Bilibili World 2023 exhibition in Shanghai, China, we have information that ASUS is preparing mass production of these zero-cable GPU solutions. Scheduled to enter mass production in Fall, ASUS plans to deliver these GPUs and accompanying motherboards before the year ends.

Additionally, it is worth noting that the motherboard lineup is called Back To Future (BTF), and the first GPU showcased was the GeForce RTX 4070 Megalodon. The PSU connectors are placed on the back side of the BTF board, while the CG_HPWR connector sits right next to the PCIe x16 expansion slot and looks like a PCIe x1 connector. You can see images of both products below.

A few weeks ago, we reported that NVIDIA is already shipping its GeForce RTX 4070 Founders Edition cards with an improved 12VHPWR connector called 12V-2x6. However, today we learn that NVIDIA is also now shipping GeForce RTX 4090 Founders Edition with an improved 12V-2x6 connector. Thanks to the Reddit user u/prackprackprack posting in r/NVIDIA, the user reported that his Founders Edition RTX 4090 has shortened sensing pins on the connector. If not adequately plugged in, the sensing pins will not allow the card to draw full power and melt the connector. Besides RTX 4070 FE, the RTX 4090 FE is now updated as well, which makes sense as it is the most power-hungry card in the family. However, this may be a partial 12V-2x6 implementation. Below, you can see images showing shortened sensing pins.

A few days ago, we reported that NVIDIA and PCI-SIG have been doing some work around the existing controversial 12VHPWR power connector to make some improvements and prevent issues that happened along the way. Called 12V-2x6, the connector features minor revisions, and you can read more about it here. Today, we learn that NVIDIA has already been shipping implementations of the new 12V-2x6 connector in GeForce RTX 4070 graphics cards, confirmed by Igor's Lab. Majority of RTX 4070 cards from AIBs shipped with 8-pin PCI connector; however, it turns out that cards that didn't use the reference 12-pin connection carried a new 12V-2x6 revision.

Below, you can see the picture comparison with the connectors from the Founders Edition of GeForce RTX 4070 and RTX 4080. The new connector on the RTX 4070 has shorter sensing pins, which can detect whether the connector is fully plugged in. If not plugged all the way, the card will not draw the required maximum power load. This should, in theory, solve connector burning issues happening in the past; however, we are still left to see. In addition, we are not sure if this is the final implementation of the new connector, as the labeling refferest to it as "H+", whereas the new connector should carry the label "H++" on its module. Igor's Lab article notes, "Since the GeForce RTX 4070 FE, NVIDIA has already been using a modified 12VHPWR connector with significantly recessed pins! While the GeForce RTX 4080 Founders Edition still relies on the header from the CEM 5.0 with only 0.45 mm offset, the GeForce RTX 4070 Founders Edition has been using a modified variant with 1.7 mm inward offset since its launch, similar to the 12V-2x6 connector."

ASUS unveiled the China-exclusive GeForce RTX 4070 Atlas Shark graphics card. If this card looks familiar, it's because the card is practically identical to the RTX 4070 Megalodon concept ASUS showed off at the 2023 Computex. The only difference between the two is that while the Megalodon features the proprietary power slot the company is introducing with its BTF-series motherboards (with their connectors and ports on the reverse side of the PCB); the new RTX 4070 Atlas Shark is a regular graphics card. It has no fancy power slot interfaces, and uses a regular 8-pin PCIe power input where you'd expect one to be. The card comes with a factory overclock of 2520 MHz, compared to 2475 MHz reference. You also get dual-BIOS, with the second BIOS engaging reference speeds and aggressive fan-speed management. ASUS is pricing the RTX 4070 Atlas Shark at RMB ¥3,299 (USD $464).

During the Computex 2023 show, ASUS had some interesting designs to showcase. Specifically, ASUS has made a GeForce RTX 4070 GPU concept without an external power connector. With NVIDIA's reference 16-pin power connector melting due to an insufficient connection, ASUS has decided to experiment by removing the connector from its GPU and placing the power source as an extra bus connector on the motherboard. Called GeForce RTX 4070 Megalodon, ASUS has made a custom power connector that goes hand-in-hand with the ASUS TUF Gaming Z790 BTF motherboard that supports this connector, and the PSU cables go on the backside of the board.

Similarly to NVIDIA's 16-pin 12VHPWR connector, this custom design is also rated for up to 600 Watts of power delivery. This results in a design that facilities the user error of not correctly pushing the 16-pin connector and causing melting. For now, the connector is referred to as GC_HPWR, but there will be an official name at launch as the company plans mass production of this concept. You can see the design of the RTX 4070 Megalodon alongside the accompanying ASUS TUF Gaming Z790 BTF motherboard.

In the course of our testing of the reference-design AMD Radeon RX 7600 graphics card, we noticed a flaw in the physical design that could impede certain kinds of 6+2 pin PCIe power cables, causing improper power connector contact, posing a potential fire hazard, theoretically. The flaw centers on the design of the card's backplate. The cutout near the power connector is designed such that certain kinds of 6+2 pin PCIe power connectors don't properly insert. Most if not all power supply units (PSUs) have their 150 W, 8-pin PCIe power connectors designed to be 6+2 pin, where you can split two of their pins away, turning them into 6-pin PCIe. While some PSU brands use a passive hook-type tail-end bridge that ensures the 2-pin portion inserts along with the 6-pin portion, some brands use more elaborate stubs that hold the two portions together. The AMD RX 7600 reference backplate design impedes these kinds of connectors.

We reached out to AMD with our findings before the May 24 review NDA, and the company got back to us with a statement:

We are very pleased with the volume of Radeon RX 7600 cards available globally from our AIB partners. We expect RX 7600 reference design cards to be available over the coming weeks with a design that accommodates all power supply cables.

NVIDIA is reportedly flexible with its add-in card (AIC) partners with their choice of power connectors for the upcoming GeForce RTX 4070 graphics card. It stands to reason that this flexibility could extend even further down the lineup, to the RTX 4060 series and below. Igor's Lab reports that NVIDIA is allowing partners to choose between the newer 16-pin ATX 12VHPWR connector, or the older [and more reliable] 8-pin PCIe power connectors, in their custom-design products. Sources tell Igor's Lab that the RTX 4070 could have two TGP classes, a 225 W-rated one that is likely to feature 16-pin connectors, and a 200 W-class that will stick to PCIe power connectors.

With typical graphics power (TGP) values for the upcoming RTX 4070 expected to be well under 300 W, graphics cards can make do with two 8-pin PCIe connectors on the card, or a 16-pin connector with a dongle that converts two 8-pin connectors to a 300 W-rated 16-pin. A pair of 8-pin inputs on the card is the more cost-effective solution, as it spares AICs from having to include that NVIDIA-designed power adapter, besides the more exotic 16-pin input on the board. We have seen pictures of RTX 4070 and RTX 4060-series Founders Edition cards, which are sure to feature 16-pin connectors. For the RTX 4070, NVIDIA could take an unconventional product launch path, with custom-design graphics cards priced on NVIDIA MSRP launching a day sooner than the ones that are priced at a premium. It's possible that the MSRP cards could come with 8-pin PCIe connectors.

While NVIDIA has launched high-end GeForce RTX 4090 and RTX 4080 GPUs from its Ada Lovelace family, middle and lower-end products are brewing to satisfy the entire consumer market. Today, according to the kopite7kimi, a well-known leaker, we have potential information about the configuration of the upcoming GeForce RTX 4060 Ti graphics card. Featuring 4352 FP32 CUDA cores, the GPU is powered by an AD106-350-A1 die. On the die, there is 32 MB of L2 cache. To pair, it has 8 GB of GDDR6 18 Gbps memory, which should be enough to power games at 1440p resolution, which this card is aiming for.

The design of the cards reference PG190 PCB is supposedly very short, making it ideal for ITX-sized designs we could see from NVIDIA's AIB partners. Interestingly, with a TDP of 220 Watts, the reference card is powered by the infamous 16-pin 12VHPWR connector, capable of supplying 600 Watts of power. This choice of connector is unclear; however, it could be NVIDIA's push to standardize its usage across all products in the Ada Lovelace family stack. While the card should not need the full potential of the connector, it signals that the company could only be using this type of connector for all of its future designs.

NVIDIA is responding to reports of the 12+4 pin ATX 12VHPWR power connector of its new GeForce RTX 4090 "Ada" graphics cards being unreliable, and posing a potential fire hazard. The company has reportedly instructed its add-in card (AIC) partners, companies that sell custom-design graphics cards; to collect all retail graphics cards with burnt power connectors, and send them over directly to NVIDIA HQ for investigation. Reports of the 12VHPWR connectors overheating due to improper terminal contact aren't new, but this is the first time a retail product implementing the connector is experiencing reliability issues.

It came to light when a Reddit user posted pictures of a melted 12VHPWR connector from an NVIDIA-supplied adapter that converts four 8-pin PCIe to one 600 W-capable 12VHPWR. There is also charring on the female connector on the card, but the user claims that the card is functional. Later this week, another Reddit user posted similar pictures of a burnt connector for their RTX 4090 card. NVIDIA director of global PR for GeForce, Bryan Del Rizzo, in a statement to The Verge, said that the company is in touch with the first owner who reported this problem, and is reaching out to the other, as part of their investigation.

The upcoming graphics cards based on PCIe Gen5 standard will utilize the latest PCIe connector with double bandwidth of the previous Gen4 that we use today and bring a new power connector that the next generation of GPUs brings. According to the information exclusive to Igor's Lab, the new connector will be called the 12VHPWR and will carry as many as 16 pins with it. The reason it is called 12VHPWR is that it features 12 pins for power, while the remaining four are signal transmission connectors to coordinate the delivery. This power connector is supposed to carry as much as 600 Watts of power with its 16 pins.

The new 12VHPWR connector should work exclusively with PCIe Gen5 graphics cards and not be backward compatible with anything else. It is said to replace three standard 8-pin power connectors found on some high-end graphics cards and will likely result in power supply manufacturers adopting the new standard. The official PCI-SIG specification defines each pin capable of sustaining up to 9.2 Amps, translating to a total of 55.2 Amps at 12 Volts. Theoretically, this translates to 662 Watts; however, Igor's Lab notes that the connector is limited to 600 Watts. Additionally, the 12VHPWR connector power pins have a 3.00 mm pitch, while the contacts in a legacy 2×3 (6-pin) and 2×4 (8-pin) connector lie on a larger 4.20 mm pitch.
