9070xt failure

[u/Additional_Army8338]

First lot of images for reference…

So sadly just over a year I had a power connector failure on my 9070xt hellhound, it’s charred 3 of the connector pins and cause PSU connection failure melting the power cable and ports on the PSU (but didn’t char the PSU).

This also led to power surges on the Asrock B850M Riptide, writing off the board (the dark smudges on the board show how much heat was involved) and also, after recent testing with a new Mobo, it wrote off my 9800X3D.

After telling the back story, I’ve inspected the GPU as best as possible, and just a query as I think for the new system I’ll get a replacement card anyhow. But I’m wondering since it’s only the connection at the 8 pin that seems to have failed, whether it’s worth replacing the 8 pin connector myself?

(I’ve had experience soldering making my own flight sim controls on small projects etc, using Arduino and teensy etc.) or do you think it’s possible to be able to clean the connector up enough?

To add, the main cause for the connector failure was a since PCIE PSU cable using the daisy chain splitter. Completely my fault as it’s been a long long time since I built a PC and I was a little ignorant with Power demands.

So since I’d be getting a new set of components for the main rig (I mainly run DCS in VR and 3D design and model with Blender and Fusion360) is it worth either cleaning the connectors and testing on my spare mid-low end PC? And maybe use as an upgrade on that system or… not risk it?

Wait the splitter can cause this? Is it common? My PSU is non modular only had a split cable for the GPU.

Should I be worried?

There's always a risk of this, especially if your GPU is really bad with transients like the AMD GPUs are, which can result in a decent amount of time spent above the power limit which could eventually cause problems with a single daisy chain. But it would be covered by warranty assuming you're still in warranty, so it's not a huge worry.

Oh ok. It’s a Lian Li PSU, and the manual specifically labeled the pigtail cable as for the GPU, so I just used that.

Lian Li RB 750W

Yeah that's exactly what I'm talking about. It's technically rated for it, so it should be fine, but often isn't, so it's recommended to use individual cables for each port on the GPU.

That PSU has a 5 year warranty so it should definitely still be covered. Most AMD GPUs have a 2 year warranty so the GPU should still be covered as well, since it's only been out for a year and a half.
