XFX Black Edition 850W Power Supply Review

XFX jumps into the PSU market at the 850 watt mark which has proven to be the toughest watermark for many manufacturers when it comes to building a truly outstanding power supply. We have seen many fail here. Can XFX pull it off and continue to diversify its product lines while keeping the trust of the enthusiast?


XFX is a division of PINE Technology Holdings Limited (along with Samtack) which was founded in 1989 and is headquartered in Hong Kong. The XFX division is a leading AIB partner of NVIDIA based video cards and motherboards. Recently however, XFX has taken to expanding their product portfolio to include ATI based video solutions and now computer power supplies. With PINE's worldwide distribution network, XFX could be poised to become one of the next big brands in the consumer power supply market. Today's Black Edition 850W (P1-850B-CAG9) is produced in conjunction with none other than Seasonic who was responsible for helping Corsair launch their first highly successful line of power supplies.

Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During that more than 30 years as a company Seasonic has cultivated lines of power supplies that are today some of the standard bearers for efficiency and quiet computing. This focus, and their reputation for quality, has lead to a real explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, Corsair, PC Power and Cooling, XFX, and of course under its own Seasonic brand.
