bad power supply = dead cpus?

I was doing some spring cleaning and ran across the first motherboard I bought, the first pc I built. That's a Tyan Tiger s2460 with dual amd athlon 2000+ mp's. Not knowing what I was doing, I made the mistake of buying one of those $20 500w psu's.... If you look at the 20pin connector in the upper right hand corner, you can see what happened lol. What's the chances that both of those cpu's are dead? It didn't kill the video card or sound card, both of which are still in use in this pc I'm on now. Is it safe to say that because the video card and sound card are ok, that the cpu's are too?

Well, I can't really speak from experience, but I would guess that they're OK. Try putting them in an old working system if you have one - see what happens.

IDK but will offer what little I can. Looking at this pic http://www.jonnyguru.com/atx/index.html
it will be seen the +5V was not doing too well

From my study: What will kill board componets are shorted electrolytic capacitors. When they fail shorted vs open. The VRM/fets can no longer do thier demanding work and hardware dies. If the caps & fets on the board look good you probably are OK.
Is there any discoloration on the pcb's backside near fets?? Yes=not so good. No=your probably OK.

A good PSU/UPS is a must for me. A quality 350W PSU>>>500W pos PSU.
