Inside:

How polite

Work

Of

Art

    Wow - the inside is totally different than most other power supplies I have seen so far. The interior has two levels of printed circuit board, and I'm sure this design is what leads to the power supply being the same size as its less powerful siblings. A rather large heatsink takes up one side of the power supply, and this is directly in line with the 80mm fan. The fan draws air from the case, and moves it over the heatsink and out of the PSU.

Cables:

24pin mobo cable	4&8pin 12v plugs	4x PCI-E
Molex/FDD	SATA	Manual

    As this is a 1000W PSU, one might expect enough connections for about 50 devices, but this is not the case. Instead, it's about pure, clean power to the motherboard and graphic cards. The wire used is 18 gauge and is UL listed. All the cables are sheathed in black plastic mesh except for the four PCI-E cables - they are sheathed in red mesh. The breakdown on the cables goes like this: the standard 24pin main cable, a separate 4pin and 8pin 12volt cable, four PCI-E cables, two cables with three Molex plugs and one FDD plug, and two cables with three SATA plugs.

Installation and Testing:

    Installing the OCZ ProXStream power supply is like installing any other power supply. The 1000W unit has the added benefit of being the same size as lower wattage power supplies, so this will install like any other unit. Slide the power supply into the proper location and use the four supplied screws to secure the power supply to the case. Now for testing. Since we at VH can't afford to spend $50,000 on a Chroma C8000 Automatic Power Supply Test System and Dice refuses to get one for review, we can only really test the PFC rating of a power supply. I did this by generating a 160W power load, along with the power load from the computer hardware listed below. Also, showing voltage readings under idle and load conditions don't mean a thing without the proper test equipment, so my testing for now on will just show the Power Factor.

• ECS RC104L/800M

• Intel P4D 930+ 3.0GHz CPU

• ASUS EAX1950Pro Graphics Card

• 2GB DDR2 RAM

    Seasonic Power Angel will be used to read the efficiency of the power supply under load. With my system setup, there is no way I'm going to get near the max wattage rating of this PSU, so we shall see the PFC rating under a normal system.

Conclusion:

    In past reviews, I have said that 600-700, and even 800W, PSU's are not needed in a standard computer setup. The same goes for this 1000W unit. The OCZ ProXStream 1000W PSU is intended for those with servers and the ones experimenting with quad core GPU and CPU systems. The average Joe need not apply for this... unless you want to impress your friends, then by all means go out and grab one.

    Overall, this is a strong power supply and it's a shame I can't test it to its full ability. The look of the OCZ ProXStream 1000W is more industrial than a lot of other units being offered. No bling on this unit; instead, the attention grabber is the 1000 watts of clean power it produces. The 80mm fan is quiet and keeps the power supply cool. Hmmm... makes you wonder why other power supplies use more than one fan in a lower wattage unit.

    If you are in the market for a high wattage power supply to give your hardware all the juice it can handle, then the OCZ ProXStream 1000W is the power supply for you. It can certainly handle that quad system you have been dreaming about. I would like to thank OCZ for sending out this unit for VH to review.
