In Win Commander II 1200Wby Martin Kaffei on June 10, 2011 1:10 PM EST
Cracking open the case, we can see an Andyson design with DC-to-DC VRM, three large heatsinks, and not much space between the components for airflow. The EMI filtering consists of four Y caps, two X caps, and some chokes. Since the PCB was too short, Andyson chose to glue some Y caps in the air and connected them with small cables. There is no MOV and the solder point for the Thermistor is bridged. Most cables have shrink tubing.
The main caps are two Panasonic HC with 400V. They are rated at 105°C (2000h endurance), which is unremarkable. The capacitors in the secondary circuit are from Teapo (SC series). The shielded DC-to-DC modules on the bottom right use all solid capacitors. The main MOFETs are two 24N60C3 in a very big housing, which is good for the thermal resistance. This PSU has SR (synchronous or active rectifying) with some IRFB3206 transistors that have excellent characteristics for this kind of application. In the bottom right, there's a very large safety IC. The PS232S supports OCP for six rails (+3.3V, +5V and the four +12V rails). Overall In Win has chosen a densely packed layout with modern technology.
