After removing the four screws, I disassembled the power supply and had a look inside, on its design and components used.
The PCB is somewhat small, underpopulated, featuring two small heatsinks. The soldering is decent enough, with no scrapings or added solder balls.
The smoothing, reservoir capacitor is a CapXon (470μF, 420V, 85°C). The secondary side is further filled with CapXon caps. These are not reputable caps unfortunately, and it would have been nice to see some Chemi-Con or Nichi-Con caps instead.
The secondary is controlled by a monitoring integrated circuit PS229, for which unfortunately, I couldn't find any specs on the manufacturer website.
The cooling fan is provided by Yate Loon electronics and is the model type D12SH-12 (12V, 0.45A, 2200RPM, 88.0 CFM, and 40 dBA).
