Lian Li are using a Hong Hua HA1225M12F-Z fan – this is a commonly seen fluid dynamic bearing (FDB) fan in high end units, such as those from Seasonic. It is rated 12V and 0.45A. This fan can rotate to a maximum speed of just over 2,000rpm.
The OEM for this power supply is Zhong Yuan Power, not an OEM we see very often in our testing. This is a half bridge design with an LLC resonant converter featuring synchronous rectification – generating the minor rails via DC-DC converters. They are using a high-grade 105C-rated Capacitor from Nippon Chemi Con in the primary stage, rated 420V 1010uF. Other capacitors in the unit are from Rubycon as well.
Soldering quality is decent, and the overall build quality seems ok on the main PCB. Over Power Protection (OPP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), Over Current Protection (OCP), Over Temperature Protection (OTP), Under-Voltage Protection (UVP), Surge and Inrush Protection (SIP), and No Load Protection (NLP) are all included.
