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.
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.
