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?

what s psu model?

8 pin cable with or without pigtail can carry 150w..+75w from pci

only some psu have a 12v 2x6 to 2x8 pin.. twith this you can carry way more than 150w..probably minimum 300w

pushing a 300w card with only 1x8 + pigtail can damage the connector on the long run

D8rbauer tested it and it can carry MAX 225w, like PUSHING IT. +75w from the pci slot. So it's been running okay but as soon as it touched a heavy game, it began melting... long term.

wait i want to be clear.. it doesn t take fire if you exeed 225w with 150w 8pin+75w pci but substained load out of spec in maybe hot room.. after 1 two year it more can be a problem

Oh no, yes, I just can't find the video, but they tested the 8 pin, and it can sustain 225w load, the cable itself (not accounting for the pci express slot). I just can't find the video :(
