Today we're looking at OCZ's latest power supply offering: The GameXstream 700W. The GameXstream series is the milestone where OCZ leaves behind Topower as the OEM for their power supply line, and starts using FSP.

     It's amazing that this unit can put out 700W of power. This tiny housing, only 5.5" deep, actually has four 12V rails and active PFC. It's all cooled by a single 120MM fan.

     Below are a couple photos of some of the other items we find inside the OCZ GameXstream box...

     The GameXstream cables are plenty long, and the use of 90 degree connectors on the SATA connectors makes them easy to use in cases with tight access to hard drives, like those with sideways mounted drives.

* The 8-pin EPS+12V split in two, creating the 4-pin P4 connector.

     And Hallelujah! ALL of the cables on the OCZ are sleeved and not just the main and P4 cables. That's worth a full point in the aesthetics category alone.

     Now let's take a look at the label on the 700W...

     Note how the "680W" for the combined maximum 12V rating notches into the combined maximum rating for the 3.3V and 5V rails. This is because the 12V rails alone are capable of putting out 680W, but any load that is on the 3.3V and 5V load will need a part of that. It's sort of deceiving since the GameXstream 700W does not have independent regulation and a minimum load is required for the 3.3V and 5V in order to keep the 12V within spec.

     The breakdown of the 12V rails on the GameXstream is very simple. There are four, but the first two are broken down like a standard ATX12V power supply with the CPU on one rail and everything else on the other. +12V3 and +12V4 go to each PCI-e connector. 18A on each rail for this, and this exclusively, is more than enough for even a quad-SLI system. The 12V leads are actually color coded with a green stripe, blue stripe and black stripe so it's easy to tell which connector goes to what rail.
