Corsair HX1050 1050W PSU review

 

It appears as if Corsair has been releasing more high-end power supplies than RAM modules during the past few months. It was only a few weeks ago that we reviewed the currently most powerful power supply Corsair offers, the AX1200, and the exceptional TX850 V2. Today we are going to examine and review a unit in between those two, their Professional Series HX1050 modular power supply.
