Enermax Revolution 85+ 950W PSU

What's Inside?

Enermax uses a Silence RL4Z-B1352512LB-3M fan capable of 98.5CFM at 40.4dB, however thankfully Enermax tones it down to more acceptable sub-30dB at full load. While appearing to be "good enough" for the task, during testing it's clearly not as well balanced with a lower quality plastic compared to the Sanyo Denki's, which are used in the Seasonic M12D.

Inside the twin 12V transformers power everything, with the rear modular board also acting as the DC-DC converter for 3.3V and 5V as well. The third, smaller transformer is for the dedicated 5V standby. These three are wedged between two large black aluminium anodised heatsinks that direct the airflow towards the back of the case.

Matsushita supplies Enermax with its three main 85ºC capacitors, in addition to the other 105ºC ones on the main PCB too. On the DC-DC converter/modular plug PCB, here we can see seven solid aluminium capped capacitors supplied by Nippon Chemicon.


A keen feature Enermax originally showed us on its pre-production unit was the coils around the main stage MOSFETs - this is a design also employed by the Antec Signature (Delta) for example, and is not only neater, but it reduces ripple early on and is claimed to "boost efficiency" too.

While the DC-DC/modular PCB workmanship is excellent, the same can't quite be said for the underneath of the main PCB, which has clearly had some hand soldering on the left hand side. We've certainly seen worse though (the early Tagan BZ series models, for example).
