Trying to diagnosis an issue with a new rig. Purchased a 1200W plat PSU from a previous seller.
Connected the six pin from the PSU to the 6 to 8 splitter. One 8 (minus 2) into the PCI riser, the other 8 into the GPU.
On applying power, it popped several IC chips on the card. Fortunately it was a crappy test card. I removed the card leaving the riser empty, applied power again and this time it melted the splitter going into the riser. Lots of smoke and panic.
The PSU is an HP 1200W with a breakout board and 12 six pin connectors.
I contacted the seller of the PSU, and he said that the board couldn’t possibly over supply voltage.
Any thoughts on where to start looking? I don’t want to fry any of my production GPUs.
