Xfire PSU upgrade advice.

post #1 of 8
Thread Starter 
Hey guys, I just picked out the GPU i'm going to use. My current PSU will handle one with ease however when I xfire it will be lacking. The GPU is a 6950. I need a PSU that will handle Two 6950's(with small OC if any at all), a PhenomIIx6 (3.2GHz with small or no OC). I have 2 HDD's currently and would like the headroom for a 3rd.
I was thinking I would need a 850w at least for this set up. I'm on a budget..I'm upgrading my current rig so I can use the left overs for my wifes PC. So cheap is great! Thanks for any advice!

The 620W Antec unit you have is actually enough. AMD recommends a 500W peak-rated power supply to power a system that has one 6950 in it, and so therefore they would recommend a 600W peak-rated power supply to power a system that has two 6950s. Now, the 620W unit you have is not a 620W peak-rated power supply. Instead, it's a 620W continuous-rated power supply which means it has a much larger capacity than any 600W peak-rated unit.

Well, am I correct in assuming that you have either the 620W Neo ECO or the 620W High Current Gamer?

ECO NEO

Here I am thinking I totaly cheesed out on a PSUI knew it's peak rating was higher than 620, but not enough to power 2 high end GPU's lol. Thats great.

I cant find a max rating on it though, or on the site.

They're just 6950s. I mean, AMD is recommending a 500W peak-rated unit to power a system with one 6950 in it, and they have the same recommendation for the 6850, the 6870 and the 6890. The 6970 is the first one in the list above the 6950 to have a 550W recommendation.

They also recommend a 500W peak-rated power supply for the 5830, 5850, and the 5870.

You're very welcome.

Check this out:

Under full system load, Guru3D.com was able to get their test system to pull 473W from the wall outlet while they had two 6950s in Crossfire (source). If I assume that the PSU was 85% efficient during this power draw, then that would mean that their system pulled about 400W from the power supply (402.5W).
