My 9800gtx+ finally arrived but it wants more juice to run. I have a hiper 425 watt psu which is 25watts short of what I need. I was about to buy one from OC but gonna consult the professionals first. 
I have a raptor and caviar, One DVD-ROM and a CD-RW and one case fan. I wanted a psu for under £80 (not strictly) which will supply enough power and a little extra should I happen to buy more fans and stuff.
I was thinking the Coolermaster Real Power 520W modular?

Edit.
Its strange because I managed to run some games and the improvement was awesome - everything on high, 4x AA and 80fps in COD4 but it shut down. Sometimes it would get to the windows logo and restart. And the fan sort of Revs. Im guessing this is a PSU issue?
