The OCZ850GXS is nicely compact for a power supply with this kind of power. Measuring 5.9 X 5.5 X 3.4 inches, this unit should fit in any ATX case with room to spare. Meeting ATX12V v2.2 and EPS12V spec, the connectors will support both 20- and 24-pin motherboards with either 4- or 8-pin CPU power sockets. Once confined to the server realm, 8-pin connectors are showing up on high-performance mainstream boards with increasing frequency and native 8-pin support is a welcome feature here. Active PFC is always good to see, especially if you live in an area where the power delivery isn't as smooth as it could be. High efficiency and four +12V rails (18A each) are fairly common in high-end PSUs like this. So why not two 36A rails? Or some other configuration? Well, UL/EN safety specifications limit the power on each rail to 240VA ( VA = Volts x Amperes). The ATX12V spec is even tighter, limiting each rail to 18A. This may change, if it hasn't already, in response to ever-increasing demand by multiple GPU solutions. As we'll see a bit later, the specs on the label differ slightly from the above chart, which was taken from the OCZ website.
For around $200-$230 US, you'll get the following:
The retail box is wrapped in plastic and contains the PSU (in bubble-wrap,) the user's guide, a bag of five mounting screws and the power cord.
