The fan is mounted inside as shown in the image above left. There are four screws holding it in place. When removed and flipped around, we can see it is the branded with a Thermaltake sticker under Model number TT-13525 (CWT13525H12F-9). It is rated 12V 0.4A and made in China. It is a fluid dynamic bearing (FDB) fan and it is manufactured by CWT with a Thermaltake sticker simply placed on it.
As we mentioned earlier in the review, this is a CWT design and the topology is primary side APFC, Full bridge and Resonant Converter, with the secondary side synchronous rectification with minor rails generated by DC-DC converters. The transient filter has 2x X caps, 4x Y Caps, 2x CM Chokes and 1x MOV.
The PCB is quite small for a 1200 watt output power supply and there are several large heatsinks in place to help maintain cooling performance. Smaller heatsinks are on the secondary side.
In the primary stage are two 105C-rated Japanese capacitors from Nippon Chemi Con, rated 400v 470uF x2, for a total of 940uF. These caps are from the excellent KMW series. Rubycon, Nippon Chemi Con and Nichicon supply the electrolytic capacitors used in the unit. Nippon Chemi Con and Toshin Kogyo supply the polymer caps.
Soldering quality on the main PCB is pretty good overall – there are a few messy looking solder sections but nothing that would cause issues. The power supply offers OCP, OPP, OTP, SCP and UCP protections.
