Ok, but how does it perform?

     Given that the OCZ PowerStream PSU is geared towards the enthusiast, it performs well astonishing well. So well in fact that I have no idea how OCZ will keep these in stock, let alone how other manufacturers will get by with no sales. This PSU is a must have for anyone out there having line voltage problems from their motherboard. Of course not all of the voltage problems can be power supply related, in fact I have seen motherboards that operate just fine and have excellent line voltages, particularly ABIT's with their 3 and 4 phase power circuits, but when you can have a power supply that offers you adjustability then  you can make up for the motherboards shortcomings and get more speed and stability out of your overclock.

     A higher RPM fan helps in cooling the PSU down results in a cooling temperature. A PSU operating at cooler temperatures provides less voltage fluctuation...

     The OCZ PowerStream is nothing special when it comes to the overall wattage and amperage values, but it is made to perform well under load. a drop of 1 AMP 396W to 170W is a very good thing...

Under the Gun.. The overall performance of the OCZ PowerStream

     Enough is enough, by now you are probably sick of the pictures, and want to see some numbers. Well we tested the OCZ PowerStream under load and compared it to our champion, the Thermal Take Butterfly 480W PSU. We used the following components during our test...

 - Intel Pentium 4 Prescott 3.0E@3.67-3.75Ghz
 - OCZ PC4200 EL 2x512mb
 - Danger Den watercooling with 12v pump
 - Lian Li PCV2000
 - Visontek x800 Pro 256mb
 - 2x74gb WD Raptors in RAID 0
 - 1 80gb ATA-133 Maxtor IDE
 - JetArt DT-5000 fan controller

OCZ PowerStream 470W

Thermal Take 480W Butterfly

It looks like the ThermalTake once again takes the crown, but with full adjustability lets see what we can make of the OCZ PSU when its adjusted..

     Using the overcurrent protection one tends to wonder if the Tt PSU was perhaps not adjusted correctly. I trust the overcurrent more then I trust just plain numbers, especially since both power supplies are well within spec if not over spec. I'll have to say due to its features the Tt PSU is coming out and the OCZ PSU is staying in our testbed. The diagnostic LED's are a must have no matter what PSU you have, and hopefully they will be implemented into the enthusiast sector more often.

So now what?

     You need this power supply...that is the bottom line. It has all the features and more than you could ever want or need in a power supply. It is purely from a professional standpoint that this is one of the most innovative products to ever hit the market. No more over and under current problems, voltage droop mods, adjustable void your PSU warranty mods, the OCZ Unit has it all and more. With its magnificent finish, a power supply no longer has to be a brick inside you case looking ugly. As a matter of fact it looks right at home with our Danger Den chrome radiator, and the more chrome the better IMO. The only gripe I have is the lack of cable sleeving. Other than that, this beauty is a must have! ClubOC recommended...

Sleeved with a Vantec and A.C. Ryan sleeving kits the OCZ is bound to win some people over.

Resting inside a Lian Li PC V2000 the OCZ looks right at home with the Danger Den Micro BIX II radiator...
