SLI & OCZ Powerstream 600 Issue

post #1 of 12
Thread Starter 
I would just like to post this as info to other users looking at buying this PSU or are having difficulty with it in SLI machines:

As some of you are aware, I have had some problems recently. When running benches or games in SLI, I would intermittently get severe slow downs or complete shutdowns. I spent days tweaking settings and doing everything I could think to figure it out, including HDD formatting, windows reinstalls, trying many different drivers, adjusting the rails (back of the PSU), running at stock, and even under clocking my stuff. All proving un-effective. After Asking around on www.overclock.net and various other sites, I managed to find a very few instances of SLI related problems with the Powerstream 600. And after a few MSN conversations. I seem to have found a small, but recognised problem with this PSU. As I'm sure some of you will say, "I have this PSU and run SLI, and have no problems at all"... I found this a lot when trying to find other people with this problem. But the problem is there for a few of these units.
So I bought a new SLI Certified PSU (PCP&C850w) in the hope that I could actually run my SLI rig. Success, No problems, even with high GPU and CPU overclocks.

If you are not running SLI, then this PSU is a gem... Its adjustable rails are a very handy feature and is a solid as a rock when overclocking... It got my Intel 560 from 3600Mhz to 4500Mhz very easily. I would still recommend this PSU to single GPU users as it is a very capable PSU.

Just a heads up really so no one else needs to get as stressed as I have been. And hopefully save yourself some $$$.

Everyone... Thanx all for your help in regards to this, your help was invaluable as always.

Guv.

Sorry to hear you had probs,but glad to hear you got it fixed Ya, a lot of people don't realize that OCZ doesn't make power supplies. They just stamp their name on those and sell them as their brand, but they don't have anything to do with the design or manufacturing of them. They're simply a relabel.

Thanx ncsa. Just don't want other people having to stress out as much as I was. It's not nice spending so much money and not know why it isn't working. lol

Yeah but I think the problem is your 7800GTX512 x 2 ... I am sure it would run any other cards SLI fine.

Thats what I thought, but there were also a few problems with 256mb versions too. It is one of those "i might work, or it might not" situations. IMO its best not to take the chance, buy a SLI certified PSU instead hehe.

The OCZ Powerstream was on the SLI-certified list a while back, but they took it off after numerous problems and negative reviews.

Oh, I totally agree with your choice- If you have disposable income. The OCZ Powerstream 520 (The one I have, at least) is rock solid and doesn't budge, calibrated with a Digital Multimeter, it is exactly on 12, 5, and 3.3- No movement at all. This is, however, different of course than the 600, which has known problems. However, this one's been going fine ever since I bought it.
