Cooler Master are using a fluid dynamic bearing Yate Loon D14SH-12 Fan, 140mm rated at 12V 0.7A. This is not a high end fan and is clearly selected to save some costs overall.
Cooler Master are using Lite On as their OEM partner for this unit, a brand many of you will know for making optical drives and power adapters. The soldering quality on the PCB is first class, and the overall design is pretty good. This is a half topology design with an APFC converter and two FETs. An LLC resonant converter is adopted to help reduce switching losses. Six FETs control the 12V rail on the secondary side, with two DC-DC converters to generate the minor rails.
As we can see from the images above the design incorporates purple ‘anodised' heatsinks which certainly stand out – if the end user would ever have the unit apart in the real world that is. The main capacitor is rated 450 V 680uF at 105c. The TK stands for Toshin Kogyo Co. Ltd, and from what I know they are Japanese capacitors from quality sources.
The unit offers OPP/ OVP/ OTP / OCP / SCP and UVP Surge and Inrush protection.
