Well I'm upgrading my gfx card to a Radeon x1650 pro and I don't believe my PSU is strong enough to run it. The last card I had burnt out and the PC wouldnt power on until it was removed so I think that was the problem. I'm on an Emachine T3256 and I was wondering if there is any specific PSU I needed to buy or is it one size fits all? Sunbeam PSU-BKS-480-US ATX12V 480W Power Supply 100 - 240 V I was looking at this once since I'm on a budget right now, but if I order that one, will I be able to put it in? (Sorry I can't post links yet.) It has good reviews but again I don't know if it will fit in my machine. Thank you.
