Bfg gtx 260 sli

post #1 of 11
Thread Starter 
I just bought a new 260 to SLI but when I start up the gpu clients I get about 3% done on each card and my computer restarts itself. I think that I need a new power supply, the one I have is in my sig.

550W is nowhere near enough for GTX 260 SLI
I would look into a 750W PSU

At least you have the fittings to start yours up .

I bought a second GTX260 the other day to SLI with but forgot my PSU only has 2 x 6pin connectors - gutted or what!

Wattage is jibber jabber. Keep an eye on 12v rail amperage, then wattage, then efficiency. Those each eat about 230 watts when folding by the by.

Bfg gs series psu's suck because they have highly overrated specs. What is your budget for a new one?

It's definately enough amps, 650W is a bit light for SLI.

http://www.tigerdirect.com/applicati...&Sku=O261-2006

850W and less after rebate. Just another option.

Also, according to SLI Zone the lowest they give for a GTX 260 SLI is 750W for any manufacturer.
