Enermax MaxRevo 1350W Fully Modular Power Supply Review

The fan used is a 140mm Enermax Twister bearing fan which is of very high quality. I’m not quite sure why Enermax market it as a 139mm fan, but I’m not going to argue over a tenth centimeter!

Inside, we can see that this unit uses a unique heatsink layout  that has been made to secure more space for the rear connectors while keeping the unit relatively small. Notice the lack of flying wires and the clean look this gives the internals.

The first stage inside a PSU is the transient filtering. This is where the unit filters the AC power coming from the mains so there is less noise which is extremely important as it impacts the efficiency and safety of the later stages, which is partly the reason you see people investing hundreds of pounds in UPS systems which do a similar job. To do this, a system of capacitors, ferrite coils and a metal oxide varistor is used. The quality of this stage is determined by the number of components doing the filtering. Many generic units will only have a singular capacitor or won’t have a metal oxide varistor (MOV). This unit really goes the extra mile using 2 X-capacitor, 4 Y-capacitors and 2 ferrite coils, this is a very positive indicator of quality! The first stage of the filtering is contained in this metal box.

Here we can see the primary MOSFETs.

This small PCB houses the PFC controller.

Right next to it is the PWM controller board.

There are two PCBs at the back. The outermost one houses the DC-DC converters for the 5V and 3.3V rails, behind which is the modular daughterboard.

These are the primary caps which are manufactured by Rubycon and are rated at 105 degrees.

This is the famous transformer that uses a very dens coil weave to help dissipate heat and increases efficiency.

Overall, this unit has truly exceptional build quality! This was somewhat expected, but the unit employs some unique design features that take this unit from high-end to top-end.
