I've been running this in a Core I5, GTX 660 Ti system for over a year and this power supply has impressed me. First of all, great energy efficiency! My system doesn't even reach 300W on full load. 80W average on idle. Of course your mileage will vary. Quiet operation; I don't even know what this PSU sounds like, all I hear are my case fans, CPU cooler, and GPU. I bought two at the same time, one for my system, and another for my little brother who games all day, literally. I built him a low-power ITX gaming PC and this PSU has more than enough power for it. This PSU helped cut down our electricity costs. Also, it looks cool through my case window.
Doesn't come in white.
It's not modular, but I use just about every connector so that's okay with me.
Worked when it arrived.....
died after a year. Disappointing since I would have expected higher quality from this manufacturer and after review research
