Mushkin Volta 600W Power Supply Review

"Efficiency peaked practically 84%, which is good enough for our buy recommendation, even though it can’t deliver efficiency above 80% under full load (and it shuts down when pulling 600 W at very high temperatures). Since most users won’t use a mainstream product like this at its full load, we don’t see a problem here.

We’d like this unit better if it had one extra SATA power connector and one extra peripheral power connector and presented lower ripple/noise levels at +5 V and +3.3 V outputs while the unit is delivering 600 W.

Of course there are better 600 W power supplies on the market, but not at the same price range."
