Q: I have a raidmax volcano 630w power supply and i was wondering will it handle a 9800gx2 and will my system run normally with one???
A: Yes it should be able to hold that graphics card. But if you have 2 of the 9800 gx2's then you should upgrade to at least 800W. Your system should run quite well with that set up. If you have anymore questions then contact me at howaboutihelpyou@gmail.com EDIT: Also a dual core processor on avg eats up 135w and the biggests fans only eat up 35w so that guy below me sayin that processors eat up a ton of shit doesn't know his shit....I have a E8400 9800 GTX BE and a Tuniq Tower and a case with 3 fans and i only have a 500w PSU and it runs fine http://forums.legitreviews.com/about14756.html "If you are wanting to get a GeForce 9800 GX2 then make sure you have the right power supply. The minimum recommend PSU for the NVIDA GeForce 9800 GX2 is 580 watts." ^^yeah bro your good
