OCZ Technology has expanded rapidly over the last decade. No longer do they simply provide memory products for your computer, but have a vast selection of products to fulfill your computing needs. OCZ has acquired many differing companies in the last several years and have raised the bar in quality computer products. OCZ's purchase of PC Power & Cooling marked the company's dedication in the power supply sector. Most recently, OCZ has released the ZX series of power supplies.

The ZX series of power supplies is aimed at powering gaming and enthusiast systems alike and is available in 850W, 1000W, and 1250W flavors. This range of power supplies offers plenty of power for those seeking to power systems with a single GPU all the way up to a triple GPU system with dual processors. The ZX series of power supplies boast 80Plus Gold certification, fully modular cables, and a single 12V rail. Today we take a look at the ZX 850, the smallest of the three ZX series power supplies.

Specifications, Availability and Pricing

As you can see from above, the OCZ ZX 850 comes with a strong rail setup. The single 12V rail is capable of pushing 70A, which is plenty of power for even a pair of high end graphics cards these days. The 3.3V and 5V rails are equally as beefy for an 850W power supply, with the 3.3V rail rated for 24A and the 5V rail rated for 30A.

OCZ packs quite a few features into the ZX series of PSU's. As you would expect, OCP/OVP/OTP are present as well as SCP and OPP. All of the cables are modular and sleeved and the 850W version even comes with dual ATX 4+4 connectors should you need it. The ZX 850 is 80Plus Gold certified, providing great efficiency even at full load. The only thing we can find lacking is that the ZX 850 is not rated for 100% continuous output at 50C.

OCZ's ZX 850 is widely available and can be found easily. The ZX 850 PSU comes with an MSRP of $199.99. Newegg is currently selling it $10 cheaper thanks to a mail-in rebate offer. Fortunately it can be had even cheaper than that. At the time of writing this article, the ZX 850 could be found for $179.99 with free shipping and a $10 mail-in rebate dropping down the price to $169.99. That makes the ZX 850 extremely competitively priced in the 850W segment of power supplies. Those purchasing a ZX series power supply from OCZ will also be pleased to know that it is backed by a 5-year warranty.
