OCZ ProXStream 1kw OCZ1000PXS ATX PSU

Conclusion

Conclusion

The OCZ ProXStream 1000w is a great looking unit with stable voltages all the way up to 886w and quite possibly beyond. The tweakers among us will be delighted to see that the ProXStream has internal pots that can be used for fine tuning the output voltages (providing you can remove the anti-tamper glue), and with an efficiency of over 81% the unit should also appeal to those who are looking to save valuable pennies on their energy bills.

Unfortunately due to the way that the ProXStream is crammed with two levels of circuits, the unit gets very hot. To counteract this OCZ have installed a high-cfm 80mm fan that unfortunately can only be described as a leaf blower when running at full speed.

If noise isn't a factor in your next PSU purchase, then the OCZ ProXStream can be found over at SpecialTech or Tekheads retailing for around £195. This is rather expensive considering the minimalistic package you get when compared with other 1kw power supplies on the market, and personally I was expecting it to be at least £20-30 cheaper.

Update 04/03/07
We have been informed that the OCZ ProXStream 1kw has been reduced in price by £20 over at SpecialTech. This brings the retail price down to £175 making the ProXStream far more competitive in the 1kw market. For this reason, the price sub-score has been increased from 7 to 8.

Komplett


Pro's
• Great looking electroplated finish.
• Sleeved cables and easy grip molex connectors.
• Good efficiency at medium and high load levels.
• Fairly stable voltages when tested up to 886w.
• Standard sized ATX casing. Suitable for all PC's.

Con's
• Very noisy even with 0% load.
• Unit gets hot under heavy load.
• +5v rail results could have been better.

"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.
