Introduction

We would like to thank Corsair for supplying the review sample.

Corsair definitely is one of the key players in the PSU market today. Their products are characterized by high quality and performance and another important factor is the peace of mind that Corsair’s warranty provides. Currently the top Corsair PSU series is called "AX". It consists of three models, with the two smaller ones, AX750 and AX850, made by Seasonic while the AX1200 is made by Flextronics, a very large company that offers manufacturing and design services in several markets while is not a dedicated PSU OEM.

The AX850 will have the honor to be the test subject of today’s review. Briefly this PSU is 80PLUS Gold certified, utilizes a fully modular cabling design, has a single +12V rail, features an ultra-quiet 120 mm double ball-bearing fan which is temperature controlled and finally it is covered by seven years of warranty. As we mentioned above, the OEM of AX850 is Seasonic and it is based on X-850 design, an extremely good PSU so we have high expectations.
