Enermax DigiFanless 550W Review

The top of the power supply has no fan installed, so its basically a simple grill, sprayed and attached to the metal chassis.

The filtering stage has two Y capacitors and a single X capacitor. The filtering stage continues to the main PCB with one Y capacitor and four polyfilm capacitors with two ferrite coils, an MOV and a CM choke. Four mosfets from Toshiba are attached to large passively cooled heatsinks.

On the secondary side, the 3.3V and 5V are generated from the 12V by DC-DC conversion. Voltage modulation is handled by two additional PCB, which are placed on either side of the supply.

Always good to see a manufacturer not skimping and using high grade Japanese capacitors. The primary capacitor is 105c,  400V 470uF rated, and by Nippon Chemi Con, from their KMQ family.

    Damn I would have loved this! But I can’t justify a £100ish premium just for being silent.

  2. Expensive, and unless you could realistically make the entire system fanless, there is little point in the PSU being fanless, and I doubt a system that needed 500W could be – and the digital feature also seems out of place at this power level.
    I expect they will do a non-digital version at a better price point.
