A Closer Look – Interior


Internally the OEM for this unit is very likely to be FSP since be quiet! rarely work with anyone else.

The primary side is provided by a CapXcon 180uF, 420V and 105 degrees celsius rated hold-up capacitor.

The smaller filtering capacitors for the secondary side are of similar quality standards and are rated for high temperature operation.

The level of AC line filtering for this unit is also impressive, just look how they managed to squeeze all of the X & Y capacitors, MOVs and CM chokes into such a neat arrangement.

The 80mm fan is made by Protechnic Electric and has the part number MGA8012YS-A15. No details of its maximum rated RPM can be found but given the 80mm form factor and the 0.28 amps I think 3000-3500 RPM is likely.
