Hi all

I am upgrading to an entire new system, and I have some trouble finding the correct PSU. I have looked at the automatic power calculator, which says I need appr. 325W for my system, but how big a PSU should I purchase then?

I know it also rests on how efficient the PSU is, but would a 500W PSU be enough, or should I get a 600W PSU?

My entire system is as follow:

Motherboard:
ASUS P5N32-SLI Deluxe

CPU:
Core 2 Duo E6400 2.13 GHz

Memory:
Corsair XMS2 2 x 1 GB PC2-5400 CL4

GFX:
2x ASUS EN7900GT/2DHT

Harddrive:
3x SATA 160GB Disc

Beside this, I have a couple of fans, a DVD-RW drive an some other small stuff.

I don't plan on OC'ing my system by much, but on the other hand, I don't want to have my new system ready, but missing 20W of power. At the moment, I am planning on buying a Sea Sonic S12-600 PSU, as people say it is pretty silent, but any other low-noise recommendations would be happily accepted.

Please share your knowledge!

Best regards

Henrik

Please search the forum - this was recently discussed in detail. The Seasonic you mention will easily get the job done. That has to be overkill on paper but I find comfort in PS overkill. PS overload deaths can be nasty.

Hint: 12V current capacity.
