Corsair Professional HX850 850W Power Supply Review
by Michael "SKYMTL" Hoenig     |     August 5, 2009

Efficiency Testing


Idle Efficiency



Load Efficiency


From our tests it seems like the Corsair HX850 is more than able to live up to its 80Plus Silver rating as it keeps pace with some of the best power supplies on the market. Indeed, even though its output wattage is identical to that of the TX850, the HX850 is able to trample the older unit when it comes to efficiency. If this Corsair power supply can continue this trend into the rest of the tests, we may have one hell of a product on our hands here.
