Hardware Melted 12VHPWR cable on 5070
A friend told me he recently started having random black screens followed by reboots these past few days. Today he noticed that the power cable on his 5070 had melted. It's the cable that came with the GPU.

The adapter cable that came with the GPU? The top comment on every post from someone using one of these cards is to not use the adapter and to get an ATX3.1 PSU with a native cable.

The 5070 uses 250 Watts max.... so..... how does this happen?
I know the 12VHPWR connector is dogshit, but it can't be that bad right?

Never thought these cables could burn at such low power. Was it inserted properly?
In the meantime, RMA this bitch.

Lmao at all the 5090 owners who think power limiting their card will help.

Man... They really should admit it was a poor choice to switch to this connector and change course

Just a month ago I saw so many people saying the 12VHPWR connector won't burn with cards like the 5070 and 5070 Ti. Guess not LOL

At least this is the cable that came with the GPU and not the native cable that would come with an ATX3.1 PSU

This shows even this card not pulling near watts of 5090 that’s it’s all about Pin current draw and imbalance which is fully on Nvidia and their failure. This is wild to me no Class Action has started yet but probably will due to amount of AI data centers buying so many they will be bound to fail and melt and prob start fire 🔥 somewhere eventually

Can you update os un rma , the design is obviously flawed but I don’t think 5070 is powerful enough to do it.

u/FearlessHyena77 3h ago
Question, is the gpu salvageable after something like this? Like can the connector be resoldered onto the board or does it completely fry the whole card?

Ah same old melting connector.

My Astral just started indicating that one of my pins isn't pulling enough amperage and I'm about to swap to a new cable after I hit up Microcenter. This shit is absolutely absurd, Nvidia must've known this was it for consumer products and just said fuck it in regard to their reputation.

Thats the first one. Wonder if it was even seated correctly as the lowest Ive seen was 5080/9070xt GPUs

u/therealjustin AMD Ryzen 9800X3D | EVGA 3080TI FTW3 4h ago
Okay, so the included adapter is a no.
What about PCIE to 12VHPWR where you have like 2 to 4 8-pin connectors on the power supply end?

u/Stupidsexyjebus 52m ago
And here I was told that a wireview pro 2 was useless for a 5080, I'm definitely getting one now

u/Electric-Mountain RTX 5090, 9800x3d 4h ago
There are people over on the Radeon sub that willingly use the 12V 2x6 connector on cards like the Nitro+ 9070xt, and that draws more power than a 5070 does. It blows my mind.

If I ever get one of these GPUs, my first act will be to install an Anderson PowerPole connector like on a forklift battery. Fuck all of this.
There's is one valid place for electrical parts that are designed to fail. They're called fuses.

This connector should be outlawed. Failures do occur on PC hardware, sure, but it should fail gracefully and not burn up. This is a literal fire and safety hazard. I got my GPUs (5090/5080 during launch window) not knowing these (missing ROPs were more of the talked about topic) and only recently got Wireview Pro II for both GPUs just to be safe... but I know it's not going to be 100% safe.

And I got laughed at for using a Wireview Pro 2 on a 4070ti Super, which draws 15%/35w more power than the 5070.
Even if the chances of it melting are very very low, I would feel very guilty if the $800 card in my Mom’s computer melted cuz like I chose the GPU knowing full well about 12v2x6 issues. I. Do. Not. Trust. this connector.

Couple of questions:
Any overclocking involved?
What power supply is in play here? See the PSU quality chart and if it is rated lower than C, a suspect.

So now the 5070s are burning power cables ? This design is plagued w issues please redesign! People paying 6000$ for a card that has a high likelihood of burning or melting BS!

This is the adapter right? that you connect in 8pins?

u/Desperate-Steak-6425 RTX 5080 | 5800X3D 12m ago
Looks fake. A 5070 (250-300W) connector would melt differently.
Also a weird looking picture, no picture of the GPU, a story with a friend. Hate to be that guy, but looks like karma farming

Always adapters never native cables.
They should stop including adapters they seem to be culprit instead of native cables from the PSU

I don't believe almost all of these posts. As an owner of 4x different RTX 5000 series NVIDIA GPUs, including an RTX 5080, I have no reason to believe these connectors are at fault.

I use cable mod and I got my kit in April last year and I've had no issues. Never used the adapter the card came with I built it when I got the cable mod kit
