Cooler Master uses a 135mm fan from Ong Hua. Specs on the label indicate a 1800RPM maximum speed and 0.36A (or 4.32 Watts) at 12V. We can’t find much info on this brand, let alone this fan but they appear to OEM fans for countless PSU manufacturers which is a good sign.

We see a bit of filtering done immediately at the AC inlet. We see two Y-caps and an inline ferrite bead to suppress any high-frequency noise that makes it in on the cord.

A couple of chokes, and more Y and X-caps rounds out the filtering stage.

The mains power inlet connections and the Hybrid cooling mode switch both plug into the board so the entire power supply PCB can be separated from the case easily.

Most of the ‘brains of the operation on crammed on a daughterboard in one corner. Just behind the modular connection board.

Incoming AC is rectified by two large full-wave bridge rectifiers which is uncommon on this size of power supply. They are attached to one of the large heatsinks back-to-back along with a few of the Active PFC MOSFETs. You typically only see multiple rectifiers on large units rated 1KW and up.

Soldering is nice and clean. We see some smaller SMT components on the bottom of the board but all of the high power stuff is on the top side and heatsinked.

The solder connections for the main 12V rail are heavily beefed up with large copper plates at least 1mm thick soldered around the connections.

On the modular end, we see several filtering caps with spaces to add more of them, and even a spare connector space of each type for a larger model.

Minor rails have their own DC-DC converter daughter board with lots of filtering on it.

The main AC filter capacitor is a Toshin Kogyo (TK) 470uF electrolytic rated for 105C. TK is made in Japan and Cooler Master states 100% Japanese capacitors used on this model.
