news 28 Posted September 17, 2012 Corsair's updated Professional Series HX power supplies include four models; the HX650, HX750, HX850 and HX1050. All of the power supplies in the Professional Series feature modular cables, premium quality components, an energy-efficient design (now 80 Plus Gold certified) and quiet operation; and they are backed by a 7-year warranty and lifetime access to Corsair's comprehensive technical support and customer service.

The HX850 PSU delivers very good efficiency with good voltage regulation and clean DC outputs on the all-important primary rails. The HX850 is dead-silent when outputting less than 20% load and under normal operating conditions the power supply is still very quiet." Thanks!!
