OCZ's ProXStream is an extremely capable power supply that offers up to 1000 Watts of output. As you would expect it comes with four PCI-E power connectors and is CrossFire/SLI ready. In our testing we come to the conclusion that this PSU will be able to power any system you could think of while still maintaining stable output voltages at all times.

nice review. I love that you look at psu products with a more critical and quantitative eye than most reviewers. It is highly appreciated and respected by those of us who understand the need for such minute details. bravo

Great review W1zz. that is a sexy PSU, but I still prefer the Power Switch. I love the auto voltage senser. Thanks man.

Also some motherboards do not react to the power switch anymore in case of a system crash. However, what you can still do is pull the power cord.

they don't??? :confused:
at least the power cord pull out still works :D

ps: if that don't work aswell get a shotgun

or you could not damage expensive components by getting on your knees and turning the wall power point off :rolleyes: , lazy lazy pt :laugh:

what if that doesn't work?, like the putter being possesed for a energy spirit or something :laugh:

If I am turning my computer off for long periods of time, I just use the switch on the surge protector. That way my computer, LCD, speakers, and TV all go totally off. So a switch on the power supply doesn't really matter, IMO.

I've never had a problem, even with having the computer completely disconnected from power for days on end. That is why there is a CMOS battery on every motherboard.

Someones not thinking straight. This PSU looks quite value packed... I reckon it would have been 900% better if they used two fans and not one, look, the dual PCB design rules out any suggestions for one 120mm fan. However I sadly miss the power switch.. why did they exclude it? I just have one thing that I hate about it... (as well as mine).... ... wait for it...


Too many cables and no modular cables :shadedshu Try one of these in an antec 900!

maybe they didnt want it to be bigger than it already was (hence only one fan)
ive heard that these 1kw units dont fit too well in quite a few cases

This one, unlike most other 1kW PSUs, seems like it is normal sized. Most of them are longer and stick further out into the case, which is a problem for a lot of Thermaltake cases and others that place the front I/O ports on top of the case.

Which is not surprising given how little power your system uses.


BTW, I love the way he tested sound.

It is for a reason. I just googled with its name and the first result is this review at TPU.

I have always thought this PSU is one of the best.... or at least it was at the time of the purchase back in 2008.

I don't even remember wiz doing PSU reviews.

They have quite rich reviews and even recently the Seasonic Snow Silent 1050W was tested.

Which is not surprising given how little power your system uses.

Is this supposed to be an insult for the OCZ? :confused:

At this moment it is not loaded but back then I wanted to Crossfire and heavily overclock the CPU.

Something that didn't happen because of my luck with the memory modules not very compatible with my old motherboard.
I gave up and built something more fit to my budget.

But still, do you think it won't handle heavily overclocked i7 5*** processor + R9 295X2, for instance?

crmaris does those, not wiz.

No, just an observation. Probably even the worst kW out there would power your current system, so it doesn't really say anything about its quality. Nitpicking. :)

But still, do you think it won't handle heavily overclocked i7 5*** processor + R9 295X2, for instance?

Oooohh, the 295X is tricky to power. It has 4 x 20A rails, and the review doesn't mention how they're split... I would say a definite "no" on that one.

The review pretty clearly states that:

Wow! That's some massive power delivery capability. 20 Amps on each of the four rails should be enough for any video card that will come out in the near future.

So, I don't really know what you mean by "split".
Maybe Wizz may say more on this one. :(

Or, I will check it and tell you from my own experience. :)

.... you do realize this is from 2007 right? We're not in the near future anymore, we're living in a sci-fi world. :)

"Split" means the 12V rail (supply) is split in four, as opposed to monsters like these. IIRC they don't really have four separate 12V lines in there, but they split the one output into four and put some sort of over current protection on those outputs, meaning that if you pull more than 20A on one of them, it'll turn off. The 295X will do that. The review doesn't state what rails go to which connector either, so it's hard to tell exactly what will happen, but it won't work.

For more info, this is a good read. These days most, if not all, good PSU's are single rail so it's not really a problem anymore.

Oh, I see now. :( You want me to supply 2 X 28 A and those 4 X 20 A won't be enough resulting in shutting down the PSU.

It will work but not at full load when the 295X2 draws maximum current.

System power supply must support two 8-pin PCIe power connectors that are each capable of supplying 28 A of dedicated current.
System power supply must support supplying a combined 50A of current over the two 8-pin power connectors, in addition to providing power requirements for other components.

http://www.hardocp.com/article/2014/04/08/amd_radeon_r9_295x2_video_card_review/1#.VQ0CtY6Ue-0

Then again, we can also remember situations when a single AMD Radeon R9 295X2 managed to shut down a PSU (PCGH, 1200W Enermax Platimax), or even destroy it outright (Tom's Hardware, Corsair AX860i).

http://www.tomshardware.com/reviews/amd-r9-295x2-1000w-psu,3907.html


I do believe that 295X2 won't destroy it as it happened in that reported case....
