Hi everyone. I have a dell xps 8300 core i 7 2600. I upgraded the psu a while back to a antec earthwats 650w psu to run my computer with evga gtx 560ti. The psu is 650wats and has two 12v rails at 38amp. Looking for a boost in graphing performance over my Ti but dont know if my psu is up for the job for a radeon 7950/7970. Amd doest specify 12v rail requirements like nvidia does, amd only says 500 watts or higher. Looking for a single gpu solution. Any info will be appreciated. thank you

thanks for your reply. I would love to go for a 600 series nvidia cards but there is a bios issue with the xps 8300 where none of them will post. nvidia knows this but the upgrade for vbios is taking forever and dell will not release a bios upgrade. So i have no choice but to go for a 7000 series radeon. I have the 7750 actually and it works fine. SO 38amp 12v rail is enough for a 7950 ?

650W is enough for a HD 7950/7970.

Hmm, I'm having a difficult time finding that information. But I honestly think your PSU should handle them since it's certified for SLI/CF and according to Tom's review, it does not use much energy compared to the 5XX series Nvidia GPU's.

That sucks that Dell is slow on updating their equipment, that's why I always opt for custom built :)
