I have a good CORSAIR HX620 which is more than enough for my system, even if I want to double my Videocard...
But I usually help others upgrading their old PC and need to know these...
I speaking about really old PCs like an AGP using motherboard with single core CPU and a Radeon 9600 Card... (If I want to put a HD2600XT in it what PSU should do it without extra cost ... The old one still capable or not...)
One years ago, I found here a list, but it disappeared. They sum up the videocards and made groups like...
7600 GT/7800GT... xxA-xxA (Example 21-25A)
X1900XTX/8800GTX 29A-33A (Minimum-Recommended)
