Question PSU cable melted in GPU connector

[FrickinBrian]

Not sure if this should be in GPU or PSU forum, but the question is more about whether my GPU is fried. I'm 100% already getting a different PSU. Probably a Corsair SF750.

I have an MSI 7900XTX and I've been getting, what I can best describe as, loss of GPU signal during gaming. The screen will go black, and the fan will sort of ramp a bit. Only way that I thought to fix it was to remove all power and drain the capacitors by holding down the power button. I figured it was dust or maybe a bad seat, so when I took out the GPU to start dusting, I noticed that the plastic around the power connector got hot, cracked, and melted a bit. The one that melted was the (don't know what you wanna call it) the "extra 6+2 daisy-chain connector on my PCIe cable". I was able to kind of clean out some the plastic from inside the GPU connector and reseat the cables (they clicked in properly) in a different way so that the melted "daisy chain" is no longer involved.

The thing that puzzles me is... I'm still operating Windows just fine; as I am currently typing on my system right now for help. I just don't think I can run a game and push power until I get a new PSU.

I don't think I can RMA my GPU in time because it'll be a year since I bought it in 3 days.

What's the best way to go about this?

MSI graphics cards, and most graphics cards in general, carry a 3 year warranty, so you should have no problem getting it replaced IF the card is to blame.

What is the model of the current PSU?

Is this a mini ITX build?

Yup, ITX. It's the PSU that came in the Cooler Master NR200P Max. I think it's called a V850. It's 850W, Gold rated. Honestly, it might have just been a loose connection that fried it. Those cables for that PSU are quite stiff.

Yes, loose contacts ca cause that. It would be better to run 2 PCIe power cables straight from PSU instead of daisy chain to spread the load on wires and connectors.

100% agree, this is so underated as an information, if your card pulls more the 200W use 2 separate cables and not just 1 daisy chain cable
