700W OCZ GameXStream Multi-GPU power supply testing

[Cooper]

Has the rule of " the more a psu weights, the better it is"? 4lbs is a lightweight.

Powerstream also weights 6lbs.
BTW these new PSUs have very small radiators which also helps reduce total weight.

[kemist]

Yea these psus are very efficient and therefore dont need large heatsinks. Read x-bit labs review on it, it is in one of the power supply roundups. They go into the electronics in it a bit, and they said they were able to hit 700 watts no prob.

edit: the xbit review is of the FSP epsilon unit, but they are equivalent

[Budwise]

how do these compare in performance and overall quality comared to the Powerstreams? Im sure im pushing my 600W pretty hard.

[eva2000]

700W GameXStream would be better than 600W Powerstreams

[LikwidKool]

I was using a 600watt powerstream, and the rails stay much more stable on the GX.

Gochin your GX was loud? I even unplugged my rear exhaust fan, and I still can't hear it. I just don't want to give the wrong info saying it is really quiet, but for me it is.

Nice review, bad psu

Nice review, bad psu

May I ask what is wrong with it?

I love OCZ and OCZ's Powerstream 520w but.......

I had this PSU and under some hardcore conditions it crapped out I prefer Single Rail PSU's.

I guess I shouldn't of said its a bad psu, but in my opinion its bad compared to my zippy 700w and pcp&c 510 asl.

You have already had a GameXtream 600 or 700W unit and replaced it? They have barely been out for 2 weeks.

What system were you running with it? I have guys on 5GHz intel systems with Dual 1900's with no issues: http://www.bleedinedge.com/forum/sho...5&postcount=14
He is pulling 770W under full load which is 70W over rated output. If you had a faulty unit, you should contact OCZ for a replacement.

Will do, thx

[Fhqwhgads6680]

hey guys I just got one of these and will let you guys know what I think. OCZ has always been good to me, and for the price and the performance this looks to be a KILLER psu! So these would have no problems with a high;y oc'd AMD x2 and x1900 crossfire? I don't have much as far as HDD go, just a single raptor. Thanks for the review eva!

You're welcome.. i'm waiting on Gecube to provide me 2x X1900XTX/XT CF cards so will be able to torture this psu on Intel 975x CF and DFI CFX3200-DR CF rigs

holy that will be torture. I wish someone would send me 2 free x1900cf, I'd be glad to do some testing lol .... If you'd like just to suppliment, I can post a summary of my results as soon as it comes in from the egg. Looking forward to seeing your torture test results

Is there any reason to get the OCZ 700w psu over the elite Emacs (zippy) 700W monster? I mean it has 45amps at 12v...

Dumo put up a nice write up:
http://www.xtremesystems.org/forums/...ght=Emacs+700W

I was going to get it but all this hype over the OCZ 700w caught my attention.

[eva2000]

i think both would be good but 700w zippy's fan is alot more noiser and 1yr warranty i think vs OCZ's 3yr warranty

[Fhqwhgads6680]

That, and price, isn' the zippy like 250+? I hear they are great psu's but I don't have tha kind of money for a psu, plus from what it looks like so far the OCZ will perform as well or maybe even better....for 160 bucks, can't beat that! mine comes itoday WOOT!!! If its ok with you eva, I will throw my own mi write-up of it in this thread. or I can start a new thread, which ever.

I have the Zippy 700W and I had to order the OCZ. The Zippy is so loud that I couldn't stand it although I have a separate machine room in my house.

Also, it is very long and doesn't fit many cases.

Zipzoomfly said they overnight my OCZ after they missed it in the first package.

[Mankz_91]

is it right that the 12cm fan is rated at 38dBa?

thats mid blowingly loud for a 12cm fan on a PSU isn't is?
MY Hiper Type-R 580W Modular is like 19 dba, and im still consious of it.
(thats only cos the rest of the rig is silent.

what in the world do you base that on??? Lets see some numbers showing the OCZ unit outpreforming the zippy.

Cost? lol, this is xtremesystems.org not costeffectivesystems.org

Size? You arent even trying now.

Noise? The fan can be replaced and the casing can be modded.

I mean preformance wise is there any reason to get the OCZ unit over the zippy and you guys push out all this fluff. Dont tell me you dont like the zippy because its not pretty enough too, lol

[uOpt]

Still didn't get mine. First zipzoomfly forgets to put it in the package, then I call them they promise to overnight one and nothing nada nil. Argh!

On the bright side, I received the molex tools and kits

Now how do I use those molex pliers...

Can you find an example of the Zippy putting out 70W over its designed output? The link above shows a 100% load draw of 770W.

I'm sorry, Ryder, but you shouldn't make that claim.

The person in that post did not measure his consumption with a powermeter.

He used that xtreme PSU calculator which is basically pure fantasy.

Sorry.

[uOpt]

Pure Fantasy? You really think that the numbers there aren't even close? Someone puts an awful lot of work into that site...I can't believe that he just makes things up.
I do know, that at least in the past, he didn't get any help from the manufacturers to find the actual power consumption.

Yes, I measure pretty much any rig I have with my powermeter, and the results never match the calculator, not even close.

They always take the maximum rating that a manufacturer gives for a given item and add them all together, but in practice it doesn't work that way.

I shouldn't say "pure fantasy", that's not correct. But they pile a lot of bad info on top of each other.

I can do a few sample calculations and compare with what I got out of the powermeter.

ETA: you see it just starts with them taking the TDP (Thermal Design Power) of the AMD processors for the power consumption. That's just nonsense.

[epion2985]

uOpt is correct. I have also used that calculator then measured my rigs and it was not accurate at all, not even close.

RyderOCZ, even if that is true and the OCZ unit pulls 70w over the rating, can you make a claim that the zippy wont? Or even that it wont do more then 70w over the specs?

Not trying to bust your chops but yes there is an example of it. On OCforums Ross tested the 700W Zippy and he got it to I believe 850-950W before the unit finally produced instability
