The HX850 is a high performance power supply, offering a dead silent operation under all conditions. For the moment its main competitors are the EVGA 850 G3 and the Seasonic FOCUS PLUS Gold and Platinum units with 850W capacity. None of those though m...

The most notable upgrades to the Corsair Professional Series HX850 power supply are increased efficiency (80 Plus Gold versus 80 Plus Silver) and the ability to run in silent, fanless mode when the load is ≤20%. The HX850 PSU delivers very good efficiency...
The Corsair HX850 Gold is another very good product among Corsair's power supply lines. However, the unit that this unit is set to replace was a really good product and that makes it really difficult for this product to stand on its own. Indeed, while thi...
Final Words & Conclusion The new HX850 definitely belongs where it is positioned, in the professional series. The power supply does what the doctor ordered, it's really silent (unless you put 100% load on it) and the efficiency was very respectable. ...
The new Corsair HX850 Gold performed slightly better on our tests than the original HX850. Efficiency was higher at full load (at other loads it remained about the same), but the biggest advantage of the new version is that we didn't see the high noise le...

initial cost is looking a mite on the high side,
Corsair's update to the good old HX850 has been a good move. The new unit performs a little better, offers higher efficiency, and is still that same excellent build quality we've come to expect from Corsair. It's not perfect, but there are very few thi...
The HX850W power supply for Corsair is truly amongst the best. More units than I can either recall or count have passed through our hands here at Overclockers Online and perhaps only one, or two are at all comparable to Corsair’s HX850W unit. While Co...
Abstract: The Corsair HX850W has no serious drawbacks. Its voltages are stable and there is low output voltage ripple. It is highly efficient and offers a lot of connectors with which you can connect three graphics cards and about ten hard disk drives using no adapters. The only thing I can find fault with is that the fan is..
