Enermax Revolution D.F. X 1650W PSU Review

Enermax are using their PFERT-14H fan in this unit. This is a dual bearing fan, rated at speeds up to 2,500 rpm, with DC 12V, 0.56A. Enermax have a lot of literature available for this fan. It uses ‘industrial grade' dual ball bearings to reduce unnecessary friction and to optimise performance.

There is a plastic shroud covering part of the fan – along the top section. This is to forcibly direct airflow over specific parts of the design and heatsinks, underneath.

The Enermax ‘Dust Free Rotation' (DFR) function. Basically this fan spins in reverse to expel dust from the insides of the unit when it is first powered up. Enermax call this a ‘self cleaning mode'. While the fan reverses direction on start up, it is difficult to actually test if this would help remove stubborn dust over the years. It's certainly an interesting idea.

In their own words, ‘by incorporating these high-quality dual-ball bearings, the REVOLUTION D.F. X achieves enhanced stability and exceptional quality. This design not only extends the lifespan of the unit but also maximizes the performance of your system for your most demanding needs.'

We can see this is a SANR OEM manufactured design for Enermax. SANR seem to be the OEM for the Enermax Revolution D.F. X series of power supplies. This is a half bridge LLC resonant converter with DC to DC circuit design offering good output efficiency and voltage stability.

Again, we can see Enermax and SANR aren't penny pinching, as they are adopting high grade Japanese Capacitors throughout the design. A pair of Nichicon 105c rated Japanese capacitors handle the primary stage. These are rated 680uF 400V, for a total of 1360uF. Secondary stage capacitors are also high grade units we would expect to see in a power supply at this price.

The unit has OCP, OVP, UVP, OPP, OCP and SCP protections.
