I replaced the PSU with a 450W bequiet! one, which did not solve the problem. In the meantime I managed to snag another 9700 Pro of eBay, this one works flawless. I'd like to replace the caps on the non-working one, but I'll have to get some proper tools first. Anyways, thanks for your suggestions. …

This is the rating of the PSU: IMG_1834.JPG I detached everything consuming power from the PSU and the mainboard except for the CPU and the 9700, but it still won't coldboot. I'll do more research to find out if the PSU is to blame. The caps on the card are not bulging, is there any way to check …

Yes, you're right. But I suspect it would narrow down the selection. I don't think it's possible to find The One soundcard anyway but maybe a best-of-three that covers the majority of games you want to play.
