CoolerMaster PSU's are crap I wouldn't suggest any model from them see what you can find in an Antec or even an OCZ PSU is better then a Coolermaster.
the 5770's are very efficient, i have an ocz modxstream 600w With my energy meter, my psu during gaming reads about 400w, and that is with an i7 920, 6gb ddr3, and 5hdd's. I would definitely recommend ocz, especially due to their amazing warranties.
it is also enough to support crossfire, i have a friend with 2 5770's in crossfire with one of them
hope it helps
Coolermaster power supplies are not high quality psu's. They are average psu's.
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 in the USA. 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 models which are a major improvement over Antec’s older psu’s like the Basiq models.
the only recent coolermaster PSUs I recall having a positive review was the Silent Pro M 600 & 850, The rest where rather disappointing.
