BeQuiet! Pure Power L8 430W CM PSU Review

The BeQuiet! Pure Power L8 430W CM includes a 120mm SilentWings L8 fan, model number BQT T12025-MS-16. This is rated to a maximum speed of 1,600rpm up to 20.1dBa.

BeQuiet! partnered up with Seasonic on their high end power supplies this year, but this unit is a HEC/Compucase design. The overall build quality is quite good and there are several large heatsinks to help keep temperatures under control. Soldering quality is also very good.

Behind the AC receptacle is a small PCB which is home to some of the transient filtering stage components – a single X and two Y capacitors. There is also the ‘on/off switch' here.

The main PCB houses three chokes, another X / two Y capacitors and an MOV.

The primary stage capacitor is a Teapo unit rated 400V 270uF @ 85c. Secondary capacitors are also by Teapo, but rated to 105c which will help long term as they are predominately bunched in airflow restricted areas of the PCB close to the cabling.  A modular PCB also houses some of the capacitors.

The IC on the board supports OCP for two +12V rails and all the other protections. (over voltage, under voltage, short circuit, over temperature, over power).
