That should be enough! But I'm sure you already heard that answer before, so why don't you just prove it yourself. Try it! If it doesn't work then sell and buy a 600 W Seasonic. Quite sure 550W is more than enough.

Easy.

550W is enough for dual X1800XTs,(uses more power tha gtx) all your pci/pcie slots filled, 4 ide devices, dual core x2 4800+, 8 fans, ect...


550 is more than enough to handle anything out today except for maybe quad opteron+sli.

Like the people in your other thread said, YES. I am always confused by people who ask for advice and then don't listen to/believe it.

Like dguy said:

Unless you're massively overclocking/volting, or you have a ton of hard drives, a good ~450W PSU will run any single-processor/dual-video setup without a problem.

Hmmm, thanks guys I guess I'll keep this PSU and use it.

I run my Beast below, with an Antec 550W easily..
