What size PSU?

[Stumps]

What size PSU would I need for my new rig that I'm building it's equiped with the following

AMD Athlon64 3000+ skt 754 (cpu is capable of running at 2.87ghz)
EPOX 8PNA SLI
Leadtek 7900GT x2
1gb DDR400
2X Maxtor 250GB SATA2 raid 0
LiteOn DVD-ROM
Pioneer DVD-RW
Tt watercooling kit.

would an Antec 550w do the trick?

 

[acegazda]

are you overclocking both the 7900gts? If not a good 500w psu would do the trick, maybe an enhance 5150gh, ot seasonic s12 500w.

 

[Stumps]

no I won't be overclocking the GF cards, only the processor

 

[acegazda]

k, I'd recommend the enhance 5150gh, or the seasonic s12 500w, if you want quiet.

 

[Stumps]

so 500-550w plenty of power then?

Another vote for the Seasonic 500w. Future proofing and getting a 600w is also a good idea.
