Back in 2009, Corsair launched the HX850. The power supply quickly became a favorite amongst gamers and builders as it performed very well with great options and was available at a very competitive price. Add in the seven year warranty and for many it was a no-brainer that this was the power supply to have for mid-range systems. Fast forward three years and we find that Corsair is still selling the HX850 like hotcakes. Unfortunately it is starting to fall behind in the PSU market as newer, more efficient models have made it to the market. Fortunately for everyone who is a fan of the HX850, Corsair decided it was time for a refresh and gave the HX850 an overhaul. This time around it still has the same I/O specifications and awesome seven year warranty, but comes with increased efficiency, better connector availability and a slight aesthetic redesign. Corsair promises the same great performance that the unit is almost legendary for so read on as we take an in-depth look into the new Corsair HX850.
