MODDIY Recommends Latest 12V-2X6 Cables for GeForce RTX 50-series Cards

[T0@st]

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."

The melts keep a coming.

RTX Cablegate update: First RTX 5080 cable melts, more 5090 cases, MODDIY changes its upgrade recommendation page - VideoCardz.com

Looks like they figure it's a great time to cash in.

This won't cut it. The state of the art PCB needs a state of the art cable with integrated fuses and temperature sensors cutting the power to prevent melting.

 

[TheDeeGee]

I see a lot of marketing bullshit.

We know the 5090 FE and possibly a bunch of AIB's have design flaws.

No amount of cable quality can solve this.

will not help. Unless users will willingly power limit their cards to 400W.
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

There was supposed to be one standard that unifies how we power our GPUs with a single cable. Now there's two with their sub-standards and certifications and whatnot. Can anyone follow this and make and sense of it?

Mandatory XKCD:

Going back I only see four client based GPUs that have ever gone into the danger zone:

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.

And yet the 295X2 somehow used only two 8-pin PEG connectors. I could've sworn it used three.

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.

based on Paulo Gomes Team Brazil, the problem is not the cable, it is the PCB architecture, which unifies the entire power line at one point, when we use the adapter this GPU does not turn off when the cables are not connected. only when all the cables are not plugged in.

hehe.... IF the cable isn't worn enough to create sufficient resistance on one of them to make the other go poof.

Also let's consider 900W transient peaks. Are we absolutely certain this is going to cut it?

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.

So they cheaped out on stuff and used 18awg instead of 16awg cable?

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.

What safety and performance standards?

No difference in cable

Note that the 12V-2x6 and 12VHPWR connectors differ only in their socket design, while the modular cables remain identical and fully compatible.

 

[user556]

That's a myth. 12V-2x6 is using different plugs on the cable. 12VHPWR cables should be recalled.
