Enermax MaxRevo 1350W PSU review
Enermax entrusted the cooling of their best power supply on a single 140mm fan with semi transparent blades. The “twister” bearing fan has a maximum rotational speed of 2000RPM.
Enermax designs and manufactures their products themselves; therefore there is no hidden OEM behind the MaxRevo. The interior of the MaxRevo unit is remarkably tidy because of the entirely different, yet very simple design which Enermax implemented. Instead of placing the primary on one side of the unit and the secondary on the other, Enermax moved the primary towards the front of the power supply and the secondary to the rear. This way Enermax did not have to use a large number of cables inside the power supply by transferring the power directly to the modular interface PCB. Only the 5VSB line is being transferred over a cable.
The filtering stage begins with a filtered A/C receptacle and continues on the PCB as well. The total number of components, including those inside the receptacle filter is four Y-type capacitors, two X-type capacitors, two filtering coils and a MOV. Enermax also placed a standard fuse on the PCB.
The three primary capacitors are made by Matsushita (Panasonic) and are rated at 330μF/400V and up to 105°C each. The secondary side capacitors are made by Nippon Chemi-Con and by Rubycon, making this power supply an all-Japanese affair.
Because of its different layout, Enermax went with large and tall heatsinks to direct and aid the airflow of the cooling fan. Given the efficiency of the power supply, the heatsinks should be sufficient for the thermal needs of the unit.
At the rear of the power supply, the modular connector and the DC to DC circuit PCBs can be seen sandwiched together.
