Enermax Liberty Eco 620W PSU Review

What's Inside?

Enermax uses its own 120mm clear bladed, dual ball-bearing fan in the design. It's PWM controlled (the four wires) so in theory can be more accurately controlled to a lower RPM than if it was a standard 3-pin model. There's no plastic on the underside to direct the airflow inwards, like other manufacturers (CWT for example) have used - here there's no restriction on the air just going straight out the back. On the upside to that though, there's no extra noise caused by airflow restriction.

The internal topology is pretty standard - a couple of Hitachi 85ºC capacitors, two sets of black heatsinks that are set to direct the air out the back of the case, a small 3.3V/5V transformer and the single main 12V transformer in the middle. The layout has space for three 12V rails, although only two are used here, so we highly suspect it's the same PCB as the Modu 82+ but a reduced cost design.

The other capacitors are 105ºC CE-TUL models that Enermax has used for quite a while, although we're not sure of the exact manufacturer.

Overall the internal quality is very good - the soldering is excellent, everything is held solidly and nothing moves significantly when wiggled.
