Just when you thought you'd seen everything, a Taobao seller has unleashed what might be the most over-engineered power connector solution yet: a 16-pin 12VHPWR power adapter complete with its own cooling fan and real-time monitoring display. Yes, you read that right—we're now actively cooling power connectors. The $30 adapter appears as manufacturers continue struggling with melting cable problems on NVIDIA's RTX 4090 series, despite the company's claims of resolving the issue. The adapter includes an LCD screen showing real-time temperature and power consumption readings, while its 180-degree design prevents sharp cable bends that are often blamed for connection problems. However, unlike more comprehensive solutions proposed by engineering experts, it doesn't address the fundamental issue of uneven power distribution across the connector's 12 power wires.

The adapter works with RTX 4090, 4080, and 4070 graphics cards. Still, it shouldn't be used with newer RTX 50 series cards, as the sales listing doesn't mention any GeForce RTX 50 series compatibility, and the latest "Blackwell" GPU design uses an updated 12V-2x6 power connector, which still appears riddled with issues. While adding a fan to a power connector may seem excessive, an intriguing possibility is that we may soon find water-cooler power connectors for the newer 12V-2x6, so users can prevent their $2000 NVIDIA GeForce RTX 5090 GPUs from melting their power connectors. Irony aside, power delivery safety is a growing concern, and no clear resolution exists. NVIDIA has reassured users in the past that these problems are now solved, but the issues are piling up as more users get ahold of their RTX 5090 GPUs.

MODDIY has swiftly updated its Help Center site with new guidelines, following recent reports of one of its older 12VHPWR cable designs having a high temperature disagreement with an NVIDIA GeForce RTX 5090 Founders Edition card and ASUS ROG Loki SFX-L power supply unit. The company's newest batch of (2025) 12V-2X6 and 12VHPWR are manufactured with the latest specifications and standards in mind, thus given the all-clear for utilization with NVIDIA's recently introduced GeForce RTX 5090 and RTX 5080 graphics cards. Any products from the 2024 production cycle (and before) are deemed safe to use with the GeForce RTX 40-series, but not "officially" valid for anything newer.

The company's renewed guidelines state: "as of 2025, the industry standard has transitioned to 12V-2X6, replacing the previous 12VHPWR standard. Our new cables incorporate significant advancements, including enhanced terminal and connector housing materials, along with thicker wires, to provide an additional safety buffer for the latest GPUs. At MODDIY, all 12VHPWR / 12V-2X6 cables purchased from 2025 onward are manufactured in accordance with the new 12V-2X6 specifications and standards, ensuring compatibility and optimal performance with the RTX50 series GPUs. Prior to 2024, the RTX50 series GPUs had not yet been introduced, and the prevailing standard was 12VHPWR. All cables produced before this period were designed and tested for use with the RTX40 series GPUs. We recommend that all users upgrade to the new 12V-2X6 cables to take full advantage of the enhanced safety and performance features offered by this new standard." They believe that their messily-named "ATX 3.1 PCIe 5.1 H++ 12V-2X6 675 W 12VHPWR 16 Pin Power Cable" premium custom tailor-made model is the best candidate for Team Green's modern generation of gaming cards.

Recent engineering prototype leaks reveal NVIDIA's power delivery design for its RTX 5090 flagship GPU featured a jaw-dropping quad 12V-2x6 connector configuration. The prototype board, while not publicly photographed, is significantly different from the final version we have today. The quad-connector design serves multiple purposes beyond raw power delivery. Each 12V-2x6 connector, capable of delivering up to 600 W individually, creates a theoretical power ceiling far beyond reasonable requirements. More likely, the implementation allows for separate voltage rails and enhanced power stability, crucial for the card's reported 575 W TDP - a 125 W increase from the RTX 4090's specifications. This overengineered piece follows NVIDIA's historical engineering practices, where early prototypes typically feature expanded power delivery systems that are later optimized for production.

The timing of this leak happens just in time with ongoing discussions about 12V-2x6 connector reliability, particularly following documented failures. While the quad-connector design may seem excessive, it distributes power load more evenly across multiple connection points, potentially addressing thermal concentration issues that plagued single-connector implementations. Board partners like ASUS have already implemented sophisticated current monitoring solutions in their custom designs, using shunt resistors to detect overcurrent conditions across individual pins. Established hardware leaker, Panzerlied confirmed the prototype's existence on Chinese forums, alongside images of other engineering samples featuring similar power delivery experiments across multiple GPU generations.

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.

NVIDIA's flagship GeForce RTX 5090 demonstrated flexibility in power compatibility, while its sibling, the RTX 5080, struggled with stricter requirements. Recent tests by a German tech outlet, ComputerBase, reveal that the RTX 5090 can operate with three 8-pin PCI power connectors instead of the recommended four, albeit with a performance trade-off. However, the RTX 5080 fails to boot when using only two 8-pin connectors. The RTX 5090, with a default TDP of 575 W, officially requires a 600 W 12V-2×6 connector or an adapter with four 8-pin PCI cables. However, tests on the ASUS ROG RTX 5090 Astral and Zotac RTX 5090 Solid show the GPU boots even with three 8-pin cables, capping its TDP at 450 W—matching the three connectors' 150 W-per-cable spec. Performance losses are modest: benchmarks indicate a 5% drop in average FPS at 450 W compared to full power.

In contrast, the RTX 5080's 360 W TDP proves less forgiving. Attempts to run the Founders Edition and Zotac RTX 5080 AMP Extreme Infinity with two 8-pin connectors (300 W total) resulted in failure: the screen remained blank, and the card refused to initialize. NVIDIA's firmware appears to lack a lower power-limit threshold for the RTX 5080, unlike the 5090, which automatically adjusts when detecting insufficient power delivery. This requirement forces users to adhere strictly to the three 8-pin or 12V-2×6 power connectors. While the RTX 5090 offers flexibility for users upgrading from older systems, the RTX 5080's limitations may frustrate owners of less powerful PSUs. For the RTX 5090, the 5% performance penalty at 450 W may be a reasonable trade-off for avoiding costly PSU upgrades, but RTX 5080 users have no such recourse. Verifying power supply compatibility, as underpowered setups risk instability or hardware damage, is a must, and when your $2000+ GPU runs, you should at least power it properly. This experiment is more a "for science" type of run.

be quiet!, the German manufacturer for premium PC components, is proud to announce Power Zone 2. Almost twelve years after the introduction of the legendary Power Zone series of power supplies, be quiet! has revived this award-winning series and future-proofed it for a new generation of gamers. Power Zone 2 features an impressive 140 mm fan and is be quiet!'s first power supply to feature semi-passive cooling with post-ventilation and a Cybenetics Platinum rating. In other words: Power Zone 2 is energy-efficient, quiet, and cool across all load scenarios, making it a reliable investment for the future.

Power Zone: A legendary heritage
When it was released in 2013, the original Power Zone stood out in the be quiet! power supply lineup - not only did the name not fit the usual nomenclature, but it was also the company's first (and for a long time, only) single-rail power supply. Fast-forward to 2025 and Power Zone 2 is pushing the boundaries again, introducing new features to be quiet!'s portfolio of power supplies, while still sticking to its single-rail design.

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.

MSI is preparing a new selection of yellow-tipped 16-pin power adapters—as reported by VideoCardz earlier today—for inclusion with certain GeForce RX 50 series "Blackwell" GPU-based graphics card models. An official announcement has not been released—regarding the latest color coding for power connectors—but new product photos have appeared on the MSI website. The yellow sections provide a clear "visual guide" when hooking the relevant adapter up to a graphics card—full insertion is achieved when the yellow tip is fully obscured by its surroundings. MSI's latest image uploads indicate that dual 8-pin to single 16-pin adapters will likely be bundled with MSI's GeForce RTX 5070 models. The RTX 5070 Ti and 5080 product tiers will be getting three 8-pin ended adapters. A very busy-looking 4-way splitter is seemingly reserved for flagship GeForce RTX 5090 cards.

The MAG GL PSU series debuted back in 2023, featuring a similarly-tinted "dual color" safety measure—based on customer and community feedback. At the time, MSI stated that it had reacted to: "reported cases of power supply connectors being burnt when paired with high-end graphics cards. We've identified the main reason: the connectors not being plugged in properly and the connector pins suffering from fall outs. With this new cable, we successfully tackle both issues head-on." Manufacturers have continued to release new products that utilize the "problematic" 12VHPWR standard, even years after the introduction of a successor: 12V-2x6. NVIDIA and several of its board partners are reported to be sticking with the first iteration PCIe Gen 5 16-pin connector for upcoming GeForce RTX 50-series graphics cards. The TechPowerUp team inspected ZOTAC's new 12WHPWR "Safety Light" feature at the recently concluded CES trade event—a visual warning will be displayed in the event of a connection problem being detected.

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.

InWin has showcased several new server chassis models at CES—these new introductions form part of the company's efforts to expand regional IPC, server, and systems assembly operations going into 2025. New manufacturing facilities in the USA and Malaysia were brought online last year, and new products have sprung forth. TechPowerUp staffers were impressed by InWin's RG650B model—this cavernous rackmount GPU server has been designed with AI and HPC applications in mind. Its 6.5U dual-chamber design is divided into two sections with optimized and independent heat dissipation systems—GPU accelerators are destined for the 4.5U space, while the motherboard and CPUs go into the 2U chamber.

The RG650B's front section is dominated by the nine pre-installed hot swappable 80 x 30 mm (12,000 RPM max. rated) PWM fans. This array should provide plenty of cooling for any contained hardware; these components will be powered by an 80 Plus Titanium CRPS 3200 W PSU (with four 12V-2x6 pin connectors). InWin's spec sheet states that their RG650B supports 18 FHFL PCI-Express slots with four PCI-Express riser cables—granting plenty of potential for the installation of add-in boards.

The MasterWatts Eath (MWE) line of PSUs form Cooler Master is one of the most popular upper-mainstream PSUs in the fully-modular 80 Plus Gold segment of the market.

The company is backing this with a 10-year product warranty.

Here is the first picture of what is very likely the GeForce RTX 5090 "Blackwell," the successor to the RTX 4090 "Ada." The picture, its massive GPU, and layout appear to confirm the weekend's bare PCB leak. The RTX 5090 is powered by the "GB202" silicon, the largest gaming GPU based on the "Blackwell" graphics architecture. The silicon in the picture has the ASIC code "GB202-300-A1." From this ASIC code, we can deduce that the RTX 5090 may not max out the silicon (i.e. enable all SM present on it), as maxed-out NVIDIA ASICs tend to have the variant designation "450."

The "GB202" ASIC is surrounded by sixteen GDDR7 memory chips, which reportedly make the 32 GB memory size of the RTX 5090. The chip count, coupled with the large GPU package size (high pin-count), confirm that the "GB202" features a 512-bit wide memory bus. Assuming a memory speed of 28 Gbps, this memory bus should yield a stellar memory bandwidth of 1,792 GB/s. The GPU and memory are surrounded by the card's 24-phase VRM solution. This draws power from a single 16-pin 12V-2x6 power connector. NVIDIA will likely max out the 600 W continuous power-delivery capability of the connector, and give the card a TGP of around 500-550 W, if not more.

NVIDIA's GeForce RTX 5090 graphics card printed circuit board has allegedly been shown in the flesh, showing the memory layout and some interesting engineering choices. The custom PCB variant (non-Founders Edition) houses more than 40 capacitors, which is perhaps not standard on the FE reference board, and 16 GDDR7 memory modules. The leaked PCB, which extends beyond standard dimensions and traditional display connector configurations, is reportedly based on NVIDIA's PG145 reference design. The memory modules are distributed systematically: five on the left, two below, five on the right, and four above the GPU die. The interface is PCIe 5.0 x16.

As NVIDIA has reportedly designated 32 GB GDDR7 memory capacity for these cards, this roughly translates into 16 x 2 GB GDDR7 memory modules. At the heart of the card lies what sources claim to be the GB202 GPU, measuring 24×31 mm within a 63×56 mm package. Power delivery uses a 16-pin 12V-6x2 power connector, as expected. The entire PCB features only a single power connector, so the 16-pin 12V-2x6, but with an updated PCIe 6.0 CEM specification, is the logical choice.

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.
