View Full Version : 750W to be enough?

Hi all!!

I'm thinking about getting a second 7950GX2 at the end of the summer and the first thing that comes to my mind is, OK, my current PSU won't handle :thumbdwn: those two beasts, if you have in mind all the other stuff plugged in my rig.

I've come to discover that my life is nothing without modular PSU's :D , and I was checking the Thermaltake Toughpower 750W Cable managment PSU a few days ago...

Will it be enough to handle all that stuff?

According to the Nvidia website it seems like it would be able to handle Quad-Sli. they list the non-modular unit but the specs are identical to the modular one. So I would say yes it will work.

i think 750W would be enough, however, i am not sure as i do not have a quad sli setup.

if you go with a 750W PSU, i recommend going with a PC Power and Cooling PSU.

they also have 850W and 1000W PSU's that would easily power a quad-sli setup.

Well, If only i could know where to find a shop here in Germany where they are selling them... I'm not aware of any shop who has stock supplies.

I was just thinking about the Thermaltake as the price here is roughly 140 eur, around 180 dollars, not bad, huh?

Thx for the advice, though.

actually the minimum for QuadSLI as my 7950 manufacturer suggests is 700W .. so you'll be a little above the edge. no worries.
i have a Tt Toughpower 750W BTW for my QuadSLI setup .. running good!

Ya, you should be fine. I have heard so many bad things about Modular PSU's but I have one and haven't had a problem....yet.

Most 750W power supplies should easily power a powerful system with two 7950's in them. Remember a 7950 takes less power than a single X1900, and there are plenty of people using less than 750W for Crossfire.

I'd recommend something other than Thermaltake though for a power supply. Just my opinion though.
