XFX Pro Series 850W Black Edition PSU – Introduction

XFX is a company which became widely known amongst computers users for their GFX card solutions. However, like many other companies, XFX also diversified into the PSU market a couple of years ago. Since several other companies had the same idea, the competition in the PSU market today is intense and each manufacturer is trying to entice the crowds with special designs and features. Today we are having a close look at the XFX Pro Series 850W Black Edition power supply, the successor of the XFX Pro Series 850W unit which has been replaced early this year.

XFX Pro Series 850W Black Edition

The XFX Pro Series 850W that we will be reviewing today is the successor of the 2011-2012 model, which was sharing the exact same name. The “Black Edition” suffix indicates that the unit which we will be reviewing today is the brand new 2013 model. It has a very long list of features, the most basic of which probably are the single 12V voltage rail, the 80Plus Gold efficiency certification and the fully modular design. With a very reasonable retail price of $140.78 shipped (after rebate) from Newegg or $149.99 shipped from Amazon, the new Pro Series 850W power supply seems like quite a good deal already. Read on as we find more about the quality and performance of this unit.
