550 watts is cutting it close with overclocking and so many fans. So I would get at least a 600 watt to be on the safe side. You can get a better idea by using "extreme power supply calculator"

Hi - The 1st one - XFX 550 is more than sufficient for your
System and the 650 is priced too high relative the 550, and
I 2nd Brett's suggestion of buying from scan vs ebay, much safer

Tom

Actually, go for the 650 if you can - I missed the dbl OC

scancomputers_int on ebay is scan.co.uk

I 2nd your first suggestion, 550w is plenty

Hi again - plz see below (from Hardcore-Gamers website) the reason I upped my suggestion to
650w after I noticed the OC'ing of cpu & gpu you will be doing.

You don't have to agree with it, but just be aware of it.

CONCLUSIONS
Looking at power supplies, the most desirable feature is a single 12V circuit with adequate capacity. Careful checking for a suitable PCI Express connector set is vital for gaming grade video cards. Modular cables are desirable but expensive.
Using a PSU with 2x the capacity of the active gaming load will be at the peak of efficiency curve. This is why nothing under 650 W is suitable in a gaming machine, especially if overclocking is desired.
We would be happier if all PCI Express cables were simply 6-8 pin so that 2-way users have adequate resources for dual GPU cards. Providing 6 cables is feasible on a single rail PSU to support 3-way single GPU cards and 2-way dual GPU cards easily. Many 1200 W power supplies still ship with 6-pin connectors. A dual GPU setup in SLI/CFX provides a 4-way machine that can play games on ultra for several years to come.

That's the school of "too much is not enough"
but no harm in the OP reading the article.
