Antec EarthWatts EA-650 Platinum 650W Power Supply Review


Testing results (Regulation & Ripple)

The ACRF topology used by the
Earthwatts Platinum is rarely being used by high performance units because,
even though it is a relatively cheap and easy to manufacture topology, the
electrical performance it can deliver rarely competes with other, superior designs.
However, the Earthwatts Platinum 650W power supply stood its ground well, with
the maximum ripple reaching up to 58mV, about halfway up to the design
specification limit of 120mV, and the regulation floating between 2.9% for the
12V line and 3.9% for the 3.3V line.
