There is enough space between the PCB’s parts for good airflow. The heatsinks are not that large, though, so the fan will have to spin at higher speeds to remove the heat from the PSU’s internals. On the secondary side, the heatsinks are on the top PCB side since the 12V FETs are soldered on the PCB’s backside. Overall, the soldering quality is good, which is usually true for High Power products. The design is contemporary, with a half-bridge topology and an LLC resonant on the primary side. On the secondary side, a synchronous rectification scheme is used for the 12V rail, and a pair of DC-DC converters generate the minor rails.
Green ordered top-quality parts for this platform, including Infineon FETs and high-class Japanese capacitors everywhere. No wonder why this unit’s price is so high. On the other hand, I am not so fond of Globe Fan products. My best guess is that High Power doesn’t have good relations with Hong Hua, so they don’t use this brand, which dominates the PSU market. That said, this unit’s fan was well-balanced, contrary to other Globe Fan products I evaluated in the past.
