yea man, any normal ATX power supply will work.....
What do you mean by wont boot up? Will the power turn on? if so, does it make any beeps or what?
I have never blown a power supply, but I know these new cards, pull lots from teh 12 volt, So i guess you could have pulled to much current from it. You should test it with another PS before you go buy a new one, cuz that might not even be the prob...Save ya some money, but then again it would be a good idea to get a bigger PS, I bought a 450 watter just so it could handle my 9500 pro ]Which will be here today!!!
