This power supply has a Hong Hua fluid dynamic bearing (FDB) fan inside, model HA13525H12SF-Z, rated 0.50A 12VDC. Max speed is rated between 2,300 rpm and 2,500 rpm.

We didn't do a complete strip down on this unit, as it was moved internally into one of our test rigs for upcoming video content. This is a bridgeless interleaved PFC, full bridge & LLC converter with Synchronous Rectification and DC-DC converters on the secondary side.

We can, however, see this is basically a rebadged Seasonic Prime PX-2200 design. This is a double-sized PCB and it has 3x X caps, 6x Y caps, 2x CM Chokes and 1x MOV on the primary side. There are three high grade Nippon Chemi Con 105C-rated capacitors on the primary side rated 420V, 820uF each for a combined 2,460uF which is staggering.

The filtering capacitors throughout are from the two big Japanese players, Nippon Chemi Con and Rubycon. The overall build and soldering quality is superb throughout. Several large heatsinks ensure good cooling proficiency across the board.

The unit ships with OCP, OVP, UVP, SCP, OPP, OTP, SIP and NLO protections.
