This unit adopts a 135mm quality Hong Hua HA13525H12SF-Z fan. This is a fluid dynamic bearing (FDB) fan, rated 12V, 0.5A with a maximum rotational speed of 2,300 rpm.
The OEM for this power supply is Channel Well Technology (CWT) and it's under their CSZ umbrella of design codes. This is a half bridge topology with an LLC resonant converter on the primary side. The secondary side uses a synchronous rectification scheme with two VRMs generating the minor rails.
Build quality overall is pretty high and soldering quality on the main PCB is very good too. The primary stage capacitor is by TK – a company we don't often see in our power supply review tests. TK are a highly regarded Japanese brand and the primary 105C-rated cap in this unit is rated 420V with an output of 820uF. Caps on the secondary side are pretty good quality too (although not Japanese), from the likes of Elite and Chengx.
The unit is equipped with OPP, OVP, SCP, OTP, OCP, UVP, NLO and SIP protections. (NLO means ‘no load operation' and SIP means ‘surge and inrush protection').
