Bingo - I made that very mistake, before someone pointed that out.

I made the same mistake as well. 800w for that system is too much.

the silencer 750 quad works great for me

As it should - Seasonic (who builds the PCP&P Silencer series) makes a damn fine PSU.

DITTO = yeah i forgot to point that out... i had mine calculating to 800Watts but actually when i set it to single it only needs 480Watts... oh and the +12V rail needed, for power...

good call guys...

MPC's dream machine uses only a 750w psu with a quad core and 2 ultra's in sli

A good 600-700 watt will do most systems fine right now, servers omitted. By good I mean name brand, Seasonic, Forton, PC Power and Cooling, Silverstone, TAGAN, most Enermax and any brand rebadged by them (Corsair, OCZ, some Antecs, etc).

My Rosewill is a rebadged Coolmax and claims to be 600w, but only puts out 35 amps/480w across it's two rails at peak. I knew this buying it and it suits me fine, just avoid the cheapy 50-60 dollar ones and spend about 120-150 for a good one. Its worth it, having a cheapo crap out and take your system with it is not fun at all.

gah, i still don't understand what you mean when you say +12v rail. i can't believe they didn't teach me anything about power supplies in my networking clases.
are the +12v rails a physical thing? like a wire that connects to your mobo, or is it like inside the PSU? i don't understand.

It's inside the PSU. More of a rating thing. Highend GPU's use the 12v rail, so a 8800GTX will tax the 12v rail heavily.

There are two types of 12v rails: single 12v rails and multiple 12v rails. More is not always better. Say there are 2 12v rails, each with 17A. Once you hook up a GPU, it can only use one (correct me if I'm wrong) and is stuck in that 12v rail. if there's not enough amps on that rail, tough. Now, say there is one 50A 12v rail. The GPU can use as much amps as it wants, but there will still be 50A for any other 12v components in yours system. The amps rating is just how strong the 12v is. Follow? Sorry if this is not making sense.

It makes sense networking has nothing to do with PSUs...

Also, the rails on a PSU are wires soldered onto the PSU's circuit board and are the main power conductors for the bigger parts in a computer. Check out my PSU Guide - that will help you understand PSUs a lot better.

As for the best thing for you, well that's what the guide is for.

And make sure you re-calculate using that tool posted in this thread and use the correct settings. It's still a SINGLE-CPU no matter how many CORES.

EDIT:

Oooo I just saw that YH posted my guide earlier. Thanks for the support bro
