HX - High Xuality?

I could write another boring intro about how today’s computers require more power than ever before, many enthusiasts are now running multiple video cards, and how a good PSU is one of the most critical components of your computer system.  You already know all of that.

Corsair has been known among PC enthusiasts as one of the best suppliers of high performance memory products for many years.  Many companies are starting to broaden their product lines to include their own brands of power supplies, cases, and other equipment.  To this end, Corsair has partnered with Seasonic (also known for their quality power supply units since the 1980s) to deliver a quality computer power supply with the Corsair name behind it, the HX620.

The fact is that the Corsair HX620W power supply should appeal to most PC enthusiasts, as it delivers more than enough power, even with SLI setups that require hundreds of watts of electricity.  Add into the mix that this unit boasts greater than 80% efficiency, a five-year warranty,  a quiet modular design and you’ll find one interested geek.
