Enermax Revolution D.F.12 750W PSU Review

Epilogue

The Enermax Revolution D.F.12 750W has the exact extra-compact dimensions as the 850W model. PSU downsizing increases noise because the overloaded PCB doesn’t allow optimal flow. This means I cannot suggest this unit to users with noise output as their top priority. That said, at up to 460W, noise is within the 25-30 dBA range so that it will be tolerable by normal users.  You should not forget that such a compact PSU is destined for an equally small ATX chassis, where users should not be so demanding regarding noise output anyway.

The D.F.12 750W achieves good overall performance despite its tiny PCB, which doesn’t help. It is only 1-2% away from the top performers in the 750W category, which is noteworthy. Most users won’t even notice this small performance difference. The unit’s good transient response at 12V, the low ripple, and the tight load regulation on this rail help it achieve such high overall performance. The overall performance would be higher with tighter load regulation on the minor rails. What RSY needs to do in this platform, though, is to decrease inrush currents, either by using a higher resistance NTC thermistor or by adding another one in series. The APFC converter also needs tuning for higher PF readings at 230V; standby power at 230V should be lower than 0.1W, and the 3.3V rail’s transient response needs fixing.

The Enermax Revolution D.F.12 750W is a one-way road if you want the smallest available ATX PSU in today’s market, offering high efficiency, high enough overall performance, and ATX v3.1 compatibility. There is also a white version, costing ten dollars more ($150) than the black version. Enermax should find a way to lower the price tags of the D.F.12 models to make them more competitive by at least 20 dollars.
