Andyson provides the platform, which uses a contemporary design. The primary side has a full-bridge topology and an LLC resonant converter for reduced energy losses. On the secondary side, six Allpower FETs regulate the 12V rail, which feeds a pair of DC-DC converters that generate the minor rails. The build quality is good, and quality caps are on both the primary and secondary sides. On the contrary, the FETs used on the APFC converter, the full-bridge topology, and for the regulation of the 12V rails are from less-known manufacturers. Lastly, the soldering quality is satisfactory, as was the case in the 1000W model (but not in the 1200W unit).
Hong Hua provides the cooling fan. This manufacturer offers good and reliable products, so the PSU’s fan will last long if you don’t stress it under high operating temperatures (above 40 degrees Celsius). Because of the PSU’s compact dimensions, a 120mm fan was used instead of a larger one, which would offer the same airflow at lower speeds, reducing the average noise output.
