PS to power 2 GTS's under $150

post #1 of 21
Thread Starter 
I've been searching quite a bit, but I'd like to get some opinions on a good power supply for my future rig. I'm starting off with 1 8800GTX, but I think I may go SLI later and want to be prepared for it. First, do you think I should just go with a PS that will run just one GTX and upgrade the PSU when I get the second (maybe in like 6 months) or just get an overkill PSU now so I'll be prepped ahead of time? I would really like it to be under $150, and modular would be nice (but not necessarily needed) I know some PSU's under 600W can power these two cards, but I have no idea how to tell if a 550W could do it or not. I was (like many I'm sure) looking at the GameXStream 700, but I'll bet I could find better. Thanks guys!
It's about time!

Get a larger PSU that supports 2x GTX's in advance (around the 700watt+ range), i wish i'd done that. I have to go out and buy a better PSU.

That Olympia only has 1 8 pin PCIe connector, does the 8800GTX use 2 6 pins or 1 6 pin and 1 8 pin?

Make sure you got enough wires! There's PSUs out there that don't give you enough wires even if they give a lot of watts!

8800GTX has two 6-pin connectors

only with the ATI did the craziness about 6-pin and 8-pin start

You can also take a look at the Corsair HX 620.

Enough juice for SLI'd GTX's, and some.

The Silverstone is a monster as well.

ATI is an idiot. Yes I'm refering to it as a single unit of stupidity. And I'm not a fanboy... I have an Xbox 360 and a X700 Pro
