HX620 Wins TechGage Editor's Choice

"Many have known for quite a while, Corsair knows their memory and know how to release a blowout product. Well, they apparently took their smarts from that market and put it straight into their power supplies because this is a fantastic result. What's most impressive is that the HX series came out of nowhere, and then proved to be a huge winner."

Corsair HX620 receives OC3D Editors Choice

"Managing extremely stable voltages on the +3.3v and +12v rails with only slight droop on the +5v rails, It was hard to find any negative issues to talk about...The ribbon-style modular cables made a nice change from the nylon sleeving seen on almost other power supplies, and also proved to be more flexible. Corsair also seem to have avoided some of the major issues often found on other modular power supplies with the HX620, which was a great relief."
