Corsair HX850 Gold PSU gets the "Worth Buying" award at KitGuru.net
"The HX850 Professional Series Power Supply is unquestionably another strong offering from Corsair. The custom Channel Well Technology design has no noticeable weaknesses, combining a high level of efficiency with much desired, low noise levels."
TechPowerUp Highly Recommended the Corsair HX850 Gold and it also scores 9/10.
"To conclude, the new HX850 is an excellent unit which enjoys great support from Corsair through its seven year warranty. If you need a similar-capacity PSU and you have enough money to invest - since the purchase of a PSU is actually an investment for many reasons - then you should seriously consider it. Nevertheless, at this price range, you will find many other interesting alternatives with equally high performance (e.g., the excellent Corsair AX850 is currently sold for 10 bucks less at Newegg). In my opinion, Corsair should lower the price of the new HX850 a little bit, to make it much more competitive."

"For performance the HX850 is right up there with the best mid-high end units. It provides very stable readings across all load ranges and high efficiency. Like the rest of Corsairs recent PSUs this model also remains completely silent up to 20-25% load and is also quiet right up to and beyond 75% with exhaust temperatures always at a low level."

Corsair HX1050 gets the "Silver" award at Overclockers Club
"The Corsair HX1050 power supply is well made, nicely packaged and comes with a good set of accessories and all for just over $200 at most major retailers. A fair price when you look at what else is available in its class. If you are in the market for a solid power supply at a reasonable price then the HX1050 comes highly recommended. I have no hesitation in awarding the Corsair HX1050 power supply a OCC Silver award."
