Its not 80+ certified, lacks active PFC, and only has a two year warranty which isnt a good thing. The warranty tells you how reliable the manufacture thinks their unit is. The really good units have a 5 or 7 year warranty, the average ones usually have 3, to only have a 2 year warranty speaks poorly of the quality of the parts.

The PSU is the one thing in your system that wont be outdated in 3 years so buy a good one that will last you 5-7 years, the corsair 550VX is my standard recommendation for 550W units.

Corsair, Antec or Seasonic are better options. Anyway, that psu is not bad.

Coolermaster power supplies are n0ot stellar performers but they may be adequate for your needs.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. One example would be the Antec Earthwatts and the Antec TruePower New series which are major improvements over Antec’s older psu’s like the Basiq models.

Stop thinking "brand names" and think product lines. After all you don't expect the same quality out of say a Ford Escort as you would their top of the line cars. PSU manufacturers build to meet different market niches.....Antec's "Basiq" series is just as the name implies .... it's a very Basic PSU designed for those primarily concerned with budget rather than quality. The Signature series from Antec represents a standard of both electrical and acoustical excellence placing it both at the top of jonnyguru's performance ratings (10) but also on the "Editor's Choice" List at silentpcreviews.com

Coolermaster does make some fine PSU's. The Coolermaster Silent Pro M700W for example makes the "Recommended List" at silentpcreviews.com, a position it shares with the Corsair TX650W, Corsair HX520/620, Antec Truepower Trio 550, Corsair VX450W and Antec EarthWatts 430. The Coolermaster M600 gets a 9.0 rating at jonnyguru

In the 500 watt category, one of the highest scorers is the EA-500 which gets a 9.5 performance rating at jonnyguru

If twin GFX cards might be in your future, I'd get a 650 watter.....l. For comparison purposes , the list below contains performance ratings (10 scale) at jonnyguru.com / prices as per newegg on 02/26/2010 and ones w/ double asterisk (**) made it onto silentpcreview.com's Editor's Choice List:

Note: Just because you see a brand name on this list, never make the assumption that their other lines are of matching quality. Silverstone for example has other models w/ 6.0 and 7.0 ratings. And just because a specific model hasn't been tested, doesn't mean it isn't of good quality.
