From all low-end power supplies sold by Cooler Master, the Elite Power 350 W is the most decent one, being able to deliver its labeled wattage at high temperatures, main voltages inside a tighter 3% regulation, noise and ripple inside the proper range, and coming with all required components in its transient filtering stage, including the MOVs. This happens because this unit is manufactured by a different vendor (Solytech) than the other three that Cooler Master uses for their other low-end power supplies.

The main problem with this unit is its lousy efficiency, always below 80% (between 72.1% and 76.8% during our tests). Therefore we can’t recommend it, although for its price it can be used in an “emergency situation” without putting your computer at risk.

The reviewed power supply burned when we tried to pull more than 350 W from it.

The manufacturer lists features that this power supply doesn’t have: two +12 V rails (it only has one), over current protection (OCP), and over power protection (OPP). It also fails to list a protection that the unit actually has, under voltage (UVP).
