MODDIY Recommends Latest 12V-2X6 Cables for GeForce RTX 50-series Cards
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.
The Verge's Tom Warren weighed in on the matter; highlighting the need for greater transparency from key industry players: "MODDIY is now recommending that RTX 50 series owners upgrade to 12V-2X6 cables instead of using existing 12VHPWR cables. NVIDIA and PSU manufacturers need to urgently clarify the situation here, as Corsair and others have said existing 12VHPWR cables should work."

RTX Cablegate update: First RTX 5080 cable melts, more 5090 cases, MODDIY changes its upgrade recommendation page - VideoCardz.com
We know the 5090 FE and possibly a bunch of AIB's have design flaws.
No amount of cable quality can solve this.
It's 400W connector by design by factoring safe power factor of 1.5x
Either 2x of those or nothing. 1 will not and never cut it.
With 2x you will have 800w safe headroom of power to overclock and do whatever you want
Radeon R9 295X2 - 500 W
Geforce RTX 390Ti - 450 W
Geforce RTX 4090 - 450 W - new standard
Geforce RTX 5090 - 575 W - new standard
I don't remember any reports about the 295X2 or 390Ti causing problems. So it looks like the new standard isn't as good as the old one. I think 12V-2X6 and derivatives should be abandoned.
EDIT: Looking at the TPU's GPU Database, the two released 290X2 cards were rated for 580W TDP. ASUS' ARES used three PEG connectors, PowerColor's Devil 13 used FOUR.
Desktop: R7-5600X / Gigabyte B450 Aorus TUF/ 2x16GB Asgard Bragi DDR4-3600CL14 / RTX 3070 Asus KO / 1TB SSD / Core Reactor 850W / G420 Deepcool /Pichau apus
Laptop (Lenovo thinkpad e 13 gen 3/ryzen 5-5500u 1x8GB DDR4-3200CL16/1x16GB DDR4-3200CL16 / Vega 7 1 GB / 1,5TB SSD
Also let's consider 900W transient peaks. Are we absolutely certain this is going to cut it?
Some first-party cables have losen pins inside the connector after a few times of plug in pull out.
He also confirms that some of the wires shows >10A under loading, while the others are 6.2 - 8A
No burn, but 10A per pin definitely violates the 9A spec
However, both sides are designed to a same spec. So if one side is fragile, the whole spec is flawed.
The flawed plugs are only on the older 12VHPWR cables. The newer 12V-2x6 cables have different plugs, so are fixed.
And the other part of the statement is all the flawed cables should be recalled and replaced free of charge.
The specs change from 12VHPWR to 12V-2x6 are ONLY on the male connectors, GPU and PSU side.
Here's from Corsair:
It's common business practice to not admit there is a problem until after there is a solution.Err: That's too generous. It's common business practise to never admit a problem ... even after plainly offering a fix.Which I guess means that 12V-2x6 (H++) is not an actual guarantee of a fix. It just happens that the plug manufacturers are now getting their act together.
Or the spec has changed for the spring contacts but we're not privy to that section.
