View Full Version : OCZ 600SLI-ADJ bites the dust.?
WTF... Been getting PSU shutdown running presler over 5GHz and x1900xtx with this PSU and just powered on and can't get the 12v in regulation no matter what the pot is adjusted for. Bounced between 10.5 and 11.8.
Anyone else see failures like this.? Kinda happy that nothing spiked and killed anything.

Yes... unfortunately, the 600W is not up to a P4 overclock due to the dual 12v rails. Replace with the 520W; or Sparkle FSP550PLG-SLI, Zippy HP2-6460P/6500P, Zippy PSL-6701P, PC P&C 510W, or Silverstone Zeus ST56ZF. All of these are excellent single 12v units with better than 32A on the 12v rail.
It's very likely your powersupply just cannot handle the load. The OCZ 600 isn't that great of a unit (just better than average) and you'll need something powerful with a single rail design like the ocz 520w powerstream, the fortron 550w, or the silverstone 560w to power your rig at the capacity you're talking about.
Wow, Ever see the movie "groundhog day".? The supply crapped out and the +12v can no longer be adjusted at stock clocks. Just wondering if anyone seen a unit fail in this way?
I'll be looking into the Athena 850w with 46A rail.

i recommend against athena in every way
they owe me a rebate from a year ago. Then the enclosure i bought crapped out and they wont replace it. They wont even respond to me. Stay away, stay far far away.
Their BBB rating is F.
I hate to threadjack but my question kind of falls into place here. Ive got a OCZ 600w SLi and I think I will be upgrading to a dual-core opteron rig and a 7900. I definatly plan on overclocking this, but now im affraid this PSU wont be up to it because of this dual 12v rail. Ive got a PC Power & Cooling 510w SLi in the house that im sure my dad would let me use in exchange for my 600w. Do you think I should do this, or will my OCZ unit be able to handle it? Thanks.

You should be fine with a dual core opteron. It doesn't pull nearly as much power as a dual core Intel does.
The 510w SLI is definitely the superior unit.

I'll be looking into the Athena 850w with 46A rail.
I can think of better ways to throw away $300. For the price of a 700W Zippy PSL-6701P, you'd be getting a PSU whose UL file number doesn't trace and whose ratings don't add up.

You'll be fine :)

Wolf, just a related question. Doesn't the 4 pin molex connector on the ASUS P5WD2 boards (and similar) attempt to get around the multi-rail 12v limitation by feeding the first rail to the CPU when power is insufficient?
Also, isn't the 8 pin connector doing this with 800/900 series chips too? ...feeding a separate rail to each CPU core?
The only reason I ask is because there are some killer looking supplies coming out like the Fortron Epsilon, but they are still multi rail and the muscle of these supplies seems useless if there's not something else going on with these 12v hungry systems.

I doubt the 8 pin connector is being seperated at all on those boards - would take a second set of mosfets to regulate the incoming power, and my guess is they don't want the boards getting so complicated and expensive to make ;)
I also doubt the chips themselves are able to take seperate power sources for each core. Not sure about that though.
I've had an OCZ 600W bite the dust. OCZ was quick to replace.
If you really want, OCZ will even trade it with a 520W b/c they offered that to me as well.

The first 600w SLi I had wouldnt even turn on and the RMA process went very quickly. They asked me if I wanted a 520w vs the 600w, too.
They should us free set of 2x256 or 2x512 for going from 600W to 520W, though. It's not fair for them to downgrade us without offering something else. :)

I also have a OCZ Powerstream 600W...I had read and researched, and this seemed to be a great PSU, especially for the fact that I am using a DFI expert with the 8-pin connector. It is even recommended on (either this forum or DFI street) as ONE of THE BEST PSU to use with DFI expert... I have an opteron 170 and 7900GT, 2gb of gskill and WC. Any thoughts as to if OCZ 600W is good for me? dual 12V rail vs. single??

Should do ok.

Underwriter's Labratories blows, the only thing that's worse is the ahole compliance engineers that work for UL. Yea, I'm bitter about being ripped off by UL for many years now. Wouldn't trust the UL rating from a agency that is so improperly mismanaged and cost bloated.
PS: The zippy looks great though. Thanks for the tip. Only found it at BostonPC.com

To elucidate, the Athena in question has a UL file number. Said number does not trace on the UL's database. Whether or not the people at the UL are doing their jobs isn't really as much a concern for me as is the fact that a PSU out there is being sold with a stamp of approval that turns out to be a dead end. That's a warning flag to me.
Unless Athena plans to correct this error, or I can verify the innards some other way, I will not recommend this PSU. I think the untraceable number is probably a typo, as it's one number off from Topower's listing (which Athena has used in the past), but I like to be absolutely sure about these things.
The Zippy can be had at www.servercase.com, where they have it listed as an Emacs unit (same company).

Could you link to where it says the OCZ600W is one of the best for DFI expert? I'm curious. :)

I found it, it is the very near the top of this page...like the 4th paragraph down.

I have seen on numerous ocassions where people have had to change their OCZ 600W because they couldn't handle SLI/CF. They often get replaced with Epsilon 600W/700W which do the job fine.
The Zippy can be had at www.servercase.com, where they have it listed as an Emacs unit (same company).
Thanks very much for the link, my 6701P shipped today $285.00. Hopefully the last supply I'll buy for a while.

I wouldn't worry - that supply is well built enough I can easily see it holding up for years of 24/7 use.
