This PSU enough for 3 8800GTs?

post #1 of 2
Thread Starter 
Hello, I'm going to be setting up a folding rig and wanted a decently budgeted PSU, so I found this:

http://www.newegg.com/Product/Produc...tent-_-text-_-

520W PSU with 40 amps on the 12 volt single rail which I considered to be pretty good considering most budget PSUs with single rails chill like right around 20 amps.

So if I had 3 8800GTs in my board, with 4 hard drives and a 45nm core 2 quad, how do you guys think the PSU would hold up? eVGA recommends 22 amps on the 12volt rail.

I do not intend to actually put these in SLI. They will be used on a folding rig with Linux.

Thank you!

Single 8800GT consumes about 110W under load. So three cards alone would consume about 330W under full load. It really depends what you'll use along with these cards. You should be alright IMO.
