I can tell that this is an FSP platform by a small detail only, without further examination of the potentiometers on the boards. Although adjusting is tempting, you should avoid doing so because you will probably alter the PSU’s proper operation. The PCB is large, with enough space between parts for excellent airflow, which is perhaps why be quiet! didn’t bother increasing the perforations on the chassis inlet and exhaust grilles.

To achieve Titanium efficiency, FSP utilized a bridgeless PFC converter, where instead of the classic bridge rectifiers, FETs rectify the incoming AC signal. FETs have notably lower power losses than diodes, so a bridgeless PFC is more efficient. The main FETs are installed into full-bridge topology, and an LLC resonant converter is also used to boost efficiency. On the secondary side, a synchronous rectification scheme regulates the 12V rail, and a pair of VRMs generate the minor rails.

FSP used quality parts, and the soldering quality is good. All capacitors are by Japanese manufacturers, and the frameless cooling fan uses a fluid dynamic bearing for lower noise output and increased reliability.

  1. Does your Dark Power model suffer from a fan that spins with an “rrrrrrrrrrrr” noise?

    I have a Dark Power Pro 12 and some user reviews of the Dark Power 13 in the UK report that the fan noise is persistent.

    1. There are some areas where then noise is increased, because of the bearing noise, but it is too low in general.

    2. I got two Dark Power 13 100W from two different online retailers and they both have obvious bearing noise. Stay away.

      1. A bit of further messing about, it seems that the one I tried it with would make no irregular fan noise when placed fan up, but makes obvious bearing noise when oriented fan down.
