Inside we find a two heatsink design and the usual two-transistor forward converter. The primary heatsink is a little larger in volume than the other since it needs to dissipate more heat from the hotter components attached to it. On secondary side only the +12 V rectifiers are connected to the heatsink as there are DC-to-DC converters for the smaller outputs. The main cap is made by Panasonic and rated at 105°C. In Win uses different suppliers for their caps, a few from Samxon (GK) can be found at the outputs. Both the PFC transistors as well as the half-bridge transistors (K15J50D) got a large semiconductor case to improve cooling. Moreoever the EMI filtering consists of all necessary components including a MOV.
