Enermax DIGIFANLESS 550W Power Supply Review

A Closer Look – Interior

The top cover is a single piece with loads of ventilation, it was also one of the easier units to open, not that you should of course.

The interior is extremely tidy, which is going to help in a big way with the passive airflow throughout the PSU.  There are very few cables trailing around compared to most active cooled PSUs.

The main bulk capacitor is rated for 400v at 470 uF up to 105c, which is perfect for a unit of this size.

There’s a small PCB here, which looks like it has a fan connector, but it’s most likely for the DIGI monitoring systems, as it’s connected to the output ports at the back.

One thing that really stands out is how tidy the soldering is here. A lot of PSUs have excess solder and lots of glue applied to cover things, but the DIGIFANLESS is neat and tidy; you can tell it has been made with care and precision.

There’s a range of thick and high-quality heatsinks throughout, obviously these are important given the passive design.

The line-in and EM filtering, as well as the main PCB fuse.
