OCZ ProXStream 1kw OCZ1000PXS ATX PSU

Introduction & Specs

Introduction

Up until recently 1000w of power was only available to those of us with plenty of space inside our PC cases. This was a problem for a lot of people as they wanted to be able to run the latest and greatest Quad/SLI and Crossfire set-ups but just simply didn't have the space for the over-sized (and highly expensive) units that were available at the time.

In the past few months several manufacturers have made it their mission to fill this gap in the market by attempting to cram the full 1000w into units suitable for fitting into standard sized ATX cases. In all honesty most attempts have been pretty poor, with most models not being able to hold up the full 1000w for any sustained period, being extremely noisy and/or ending up so hot that you could fry an egg on top of them.

Will the recently released ProXStream 1000w PSU from the enthusiast orientated manufacturer OCZ be the answer to our prayers? Read on to find out.


Specifications

The following information has been shamelessly copied directly from OCZ's website:

The Multi-GPU Ready ProXStream 1000 Watt power supply is designed specifically for the most demanding computing environments of PC enthusiasts, high-end system builders, and die-hard gamers. With today’s top-of-the-line graphics cards consuming large amounts of energy, the ProXStream supplies stable and reliable power to quad-GPU platforms, as well as all your systems vital components.

The new OCZ ProXStream 1000W PSU utilizes a powerful, server-class core and merges it with an unparalleled compact form factor to accommodate virtually all computer cases, a requisite for today's enthusiasts and system-builders.

In terms of specification the ProXStream looks like a very capable unit. With a total of four +12v rails rated at 20a each and a combined +12v output of 70a the PSU certainly can't be accused of being underpowered. The same goes for the +3.3v and 5v rails rated at 28a and 30a respectively.

Anyway, enough of the boring stuff, let's get down to the nitty gritty...

"Today I'll be looking at OCZ's first entry into the 1000w domain with their brand new ProXStream 1kw unit based around a standard ATX sized casing. Will it be any better than the other similarly sized 1kw units we've tested recently? Read on to find out."

Not impressed tbh - enermax ftw... Agreed, fairly decent performance, but who wants fairly decent when you can have unequivocal top notch performance elsewhere?

Decent review though...

Cheers mate. If it was a fair bit cheaper then I think it would stand a much better chance. Being only a few quid different to some of the top-end units makes it hard to justify buying unless you REALLY want 1kw and you REALLY don't have space.

for a 1k psu and the size, and also using a 80mm fan, i think its a rather good psu, if they used a 120mm fan im sure temps and the sound would be dropped alot more.

Looks to be a decent unit, I like the size. I don't like the noise output though, that's a killer for me.
