Corsair HX620w Modular Power Supply

Introduction:

Corsair has been a frontrunner in the computer memory market for some time now. In a constantly changing, and sometimes hostile computer market, they've managed to make all the right moves, stay on top, and also garner themselves a highly respected and trusted name. Educated consumers have come to know that when they buy Corsair products, they're getting the best quality, and most stable components that money can buy.

Taking into account all that, when I heard that Corsair was entering the highly competitive power supply market with their own modular power supplies, I was quite interested to see what they would come up with. Did they make this reviewer giddy like a school girl, or did they let me down? You'll have to read on to find out!

I've seen a ton of power supplies over the years and this new Corsair HX620w is a sharp (read: evil) looking package. Red and black are not my personal favorite color combination though and I think Corsair missed the target by not including a red LED fan on the power supply. That would've really kicked it off and make it stand out more.

I will say that the way that Corsair completely wrapped the main power supply unit in a molded foam casing is by far the best protection I've seen on a power supply. Also thankfully they decided to go with a textured satin black finish and not a "mirrored" finish (read: fingerprint sponge). The unit felt very solid although the looks are unremarkable.
