Corsair rolled out a handy accessory that should help cable management in builds with graphics cards that have 16-pin 12VHPWR power connectors. Called simply the 12VHPWR GPU Power Bridge, the contraption inverts the power connector 180° as shown in the pictures below; so your power cable emerging from behind the motherboard tray doesn't have to make that turn. The Power Bridge hence reduces mechanical stress on the power cable from your PSU.

Unlike several such 180° power bridges of generic brands floating around online retail, some of which even convert 8-pin PCIe to a 12VHPWR; the Corsair Power Bridge comes with the quality assurance that comes with the badge. The company claims to have extensively tested it for endurance. The internal wiring between the two connectors on the bridge is tested to withstand 105 °C temperatures. Please note, that the bridge is not physically compatible with the ASUS ROG Strix and TUF Gaming graphics cards. The company is backing this with a 1-year warranty.

Amidst reports that NVIDIA has shelved plans to release a new flagship RTX 40-series graphics card to top the current RTX 4090, we are getting even more pictures of the company's ingenious product design for what could have been the GeForce RTX 4090 Ti, or RTX TITAN (Ada). Pictures of the card's cooling solution has been in the news since January 2023, with more images surfacing in June. We are getting our first images of the cooler disassembled, revealing a startling look at the engineering effort NVIDIA put into this thing.

As we mentioned earlier, the "RTX 4090 Ti" features a unique ruler-shaped PCB that's oriented along the plane of the motherboard, rather than perpendicular to it, like any other add-on card. This is to minimize the spatial footprint of the PCB, and maximize volume for the cooler—which is 4 slots, thick, with its entire thickness dedicated to heat-dissipation, and no obstruction posed by the PCB.

Colorful Technology Company Limited, a professional manufacturer of graphics cards, motherboards, all-in-one gaming and multimedia solutions, and high-performance storage, unveils two new graphics cards - the iGame GeForce RTX 4070 Ultra Z OC and iGame GeForce RTX 4060 Ti Mini. The iGame GeForce RTX 4070 Ultra Z OC features a hidden cable management design, a trending concept that is changing the standards of PC components today. COLORFUL also unveils the iGame GeForce RTX 4060 Ti Mini OC 8 GB-V, the first compact model in the RTX 4060 Ti family.

The iGame GeForce RTX 4070 Ultra Z OC features a different PCB design from the Ultra W model wherein the connector is hidden beneath the backplate. This allows builders to achieve tidier cabling, hiding the power cable from the visible side of the graphics card. The Ultra Z OC is compatible with most motherboards. For chassis, it is best paired with a case specifically designed to support this concept.

Cooler Master, a leading innovator in PC Hardware, today announced the launch of its GX III Gold series of power supply units (PSUs). Available at 650 W, 750 W, and 850 W, these PSUs feature a sleek, streamlined design, a highly durable 12VHPWR cable and ATX 3.0 compatibility, supporting the most powerful graphics cards in the industry.

Designed for power users, enthusiasts and custom builders, the GX III Gold builds on the legacy of Cooler Master's GX series. This innovative PSU offers all-new material and structural design, fully modular cabling and optimized thermal performance. Boasting 80 Plus Gold and efficiency certifications, as well as 80 Plus Titanium-level efficiency at light loads, the GX III Gold series is the best PSU in its class.

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.

ASUS today announced the Prime 750 W Gold and 850 W Gold power supplies, designed to give mainstream DIY PC users reliability and build quality without breaking the bank. The 750 W and 850 W Gold are the first power supplies to join the Prime family, bringing the ATX 3.0 standard, fully modular cables and an eight-year warranty. And whether it is the Prime AP201 MicroATX case or motherboards like the Prime Z790-A WiFi, the Prime series is synonymous with classy, understated designs that can look amazing in any build.

Build-friendly features
ASUS Prime Gold Series power supplies are loaded with all of the features that PC builders have come to expect from a high-quality PSU. Both models are fully modular, allowing users to cut down on build clutter by only using the cables they need. As ATX 3.0-compatible power supplies, the ASUS Prime Gold Series units are also fully compatible with NVIDIA GeForce RTX 40 series graphics cards, thanks to their native 16-pin 12VHPWR cable.

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."

According to Igor's Lab, who has gotten their hands on a PCI-SIG draft engineer change notice, it looks like the not entirely uncontroversial 12VHPWR connector won't be long lived. The PCI-SIG is getting ready to replace it with the 12V-2x6 connector, which will be part of the ATX 3.1 spec and the PCI Express 6.0 spec. The new connector doesn't appear to have any major physical changes though, but there have been mechanical modifications, such as the sense pins having been recessed further back, to make sure a proper contact is made before higher power outputs can be requested by the GPU. The good news is that at least in the draft spec, the 12V-2x6 connector will be backwards compatible with 12VHPWR connectors.

One of the bigger changes, at least when it comes to how much power the new connector can deliver, is that there will be new 150 and 300 Watt modes in addition to the 450 and 600 Watt modes for the sense pin detection. The 12V-2x6 connector is rated for at least 9.2 Amps per pin and the new connectors will carry a H++ logo, with th older 12VHPWR connectors getting a H+ logo. The PCI-SIG has also added stricter requirements when it comes to the cable design and quality, which should hopefully prevent some of the issues the 12VHPWR implementations have suffered from. We should find out more details once the PCI-SIG has finalised the 12V-2x6 connector specification. In the meantime, you can hit up the source link for more technical drawings and details.

Back in January, we got our first look at the cinder block-like 4-slot cooling solution of NVIDIA's upcoming flagship graphics card (called either the RTX 4090 Ti, or the TITAN (Ada). "ExperteVallah" on Twitter scored additional pictures of the cooler. Its design sees the heat dissipation surface pushed to the entire thickness of the cooler, and ventilated the entire length.

The card's PCB isn't conventional—not perpendicular to the plane of the motherboard like any other add-in card—but is rather along the plane of the motherboard, with additional breakaway daughter cards interfacing with the sole 12VHPWR power connector, and the PCIe slot. This slender, ruler-shaped PCB spans the entire length of the card, without coming in the way of its heat dissipation surfaces. The length is used for the large AD102 ASIC that's probably maxed out (with all its 144 SM enabled), twelve GDDR6X (possibly faster 23 Gbps), and a mammoth VRM that nearly maxes out the 600 W continuous power delivery design limit of the 12VHPWR.

Seasonic has launched the updated Prime PX 1600 Watt PSU that TPU spotted at Computex earlier this month, alongside two new Prime TX models at 1300 and 1600 Watt. The three models all adhere to the ATX 3.0 standard, unlike its predecessors. However, it appears that Seasonic hasn't as yet, at least, decided to update its lower Wattage models to the ATX 3.0 standard. Both 1600 Watt models feature a pair of 12VHPWR connectors, whereas the 1300 Watt model gets to make do with a single 12VHPWR connector. All three models feature no less than nine CPU/PCIe 12 V connectors and six peripheral connectors for modular cables.

The Prime PX is rated for 80 Plus Platinum and the Prime TX for 80 Plus Titanium and this appears to be the only major difference between the two models. Other interesting features include a 135 mm fan with fluid dynamic bearings and a digital hybrid fan control, as well as a bundles basic PSU tester. Both models also come with a 12 year warranty. Price wise, the Prime PX-1600 will retail for US$509.99/€459.99, with the Prime TX-1300 going for US$519.99/€479.99 and finally the Prime TX-1600 will set you back US$609.99/€549.99, suggesting a steep price premium for only a marginally more efficient PSU.

A member of the amusingly named and low populated r/4090Burning subreddit has reported a strange incident where the PSU side of his 12VHPWR connector had melted. Shiftyeyes67k shared his equipment's plight two days ago and included two photos with his story: "Started noticing a smell coming from my PSU (be quiet! Dark Power 13 1000 W) recently that smelled like burnt plastic. Decided to swap it out and noticed that the 12VHPWR cable was burned...From everything I've read this generally happens to the connector on the GPU side so I'm wondering if anyone has seen this yet?" His feedback shows that the relatively new connection standard has ongoing reliability issues, even though most 16-pin connector problem cases have affected beastly GPUs such as NVIDIA's GeForce RTX 4090.

The be quiet! Dark Power 13 1000 W PSU has native support for the 16-pin cable standard, and no type of adapter was used in Shiftyeyes67k's example. Tom's Hardware reported on this sole incident recently, and a be quiet! representative responded to the article's content (updated today): "This is a unique case and we already have reached out to the customer to learn more." The company statement continues: "As our brand is known for highest quality standards, we treat this seriously and have initiated an investigation." be quiet! recommends that any customers experiencing similar issues should contact their support team directly. Tom's Hardware has attempted to get a comment from NVIDIA about the latest problem, but "an Nvidia spokesperson said we may not hear back for a few days due to a company closure."

GIGABYTE GeForce RTX 4090 WindForce V2 may not be the company's most premium RTX 4090 custom-design graphics card, but it has arguably the best power connector design. Almost every custom RTX 4080 and RTX 4090 comes with a design where in the PCB is half or two-thirds the length of the card, and the remainder of the length is dedicated to the cooling solution, where the heatsink can extend along the thickness of the card. In case of the RTX 4090 WindForce V2, this extended portion of the cooler is recessed by half, exposing the tail end of the PCB. The 16-pin 12VHPWR power input is pointed toward the tail-end, rather than toward the top of the card.

This makes cabling very convenient, as it no longer needs to bend nearly 180° as it emerges from the back of your motherboard tray. The power cable goes straight into the connector with no bending up to a roughly 8 cm length, before making a 90° turn to the back of your motherboard tray, reducing mechanical strain on the connector. Even the NVIDIA-designed adapter included with the card (the one that converts 4x 8-pin to a 12VHPWR), should look neater. It's likely that as a WindForce-series product, this card offers the lowest tier of factory overclocks by GIGABYTE. You still get dual-BIOS, which lets you toggle between this factory-OC, and a Silent BIOS that runs the card at reference speeds, with tighter fan tuning. The selling point, however, is its unique power connector design.

FSP Group, one of the world's leading high-performance OEM and ODM power supply manufacturers, today unveils the next generation DAGGER PRO series 750 W and 850 W SFX power supplies upgraded with ATX 3.0 compliance built to power compact gaming and workstation PCs of 2023.

Channel Well Technology, or CWT in short, is a major OEM of PC power supplies and notebook power bricks. Several major PSU brands source their PSUs from CWT, across all market segments. The company apparently also sells certain reference PSUs of its own in the retail channel, the way Seasonic and Fortron (FSP) do, and showcased its latest ATX 3.0 + PCIe Gen 5 compliant PSU models. The CTT series of enthusiast-segment reference PSUs comes in 1650 W and 1350 W variants, and boast of 80 Plus Titanium efficiency, and two 16-pin 12VHPWR connectors, each capable of 600 W continuous output.

The CTB Series are the company's top SFX-L PSU models, and meet SFX12V 4.0 (ATX 3.0 analogue) standards, along with PCIe Gen 5. These come in a 1000 W variant with 80 Plus Gold efficiency, and a 1200 W variant with 80 Plus Platinum, both feature a 16-pin 12VHPWR connector. These use 120 mm fans. The CSX Series PSUs target the traditional SFX form-factor, and come in two high-wattage models—1000 W with 80 Plus Platinum efficiency, and 850 W with 80 Plus Gold. Both models offer a 600 W-rated 16-pin 12VHPWR connector.

With their signature upward positioned front air vent, Wizmax cases were unmissable at the 2023 Computex. The company showcased four of the top case models, along with a new high-wattage ATX 3.0 PSU. The GX-3 Chang and GM-3 Moon are characterized by their distinct front-panel design that looks like a Chinese room divider pattern from the mid-19th century. Measuring 518 mm x 250 mm x 585 mm, the GX3-Chang features a horizontally-partitioned layout, its width opens up plenty of height for the CPU cooler and graphics card, of 18 cm; while you can use a graphics card up to 46 cm in length. The top- and front-panels each give you enough room for a radiator as big as 420 mm. Besides eight conventional add-on card slots, you get three vertical ones.

The GM3-Moon is a more compact mid-tower, measuring 485 mm x 225 mm x 392 mm, which opens up room for up to 34 cm long graphics cards, and up to 17.5 cm tall CPU coolers. You can mount a 360 mm radiator along the front-panel, and a radiator as large as 280 mm along the top panel. The GM1 Transform has a design novelty where its front-panel cover slides sideways to reveal a mesh intake. Don't want all those front fans glaring at you? Simply pull up the opaque front-panel. This mid-tower gives you room for graphics cards up to 35.5 cm in length, and CPU coolers up to 16 cm in height, and no vertical slots. It comes in white and black color options.
