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 Perfect 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 the regulation of the 12V rails are from less-known manufacturers. The soldering quality is better than the 1200W model’s, but still not top-notch. This doesn’t affect performance and reliability; it is more an aesthetic issue for us picky reviewers.
The cooling fan is by Hong Hua, which dominates the PSU market, for a good reason. It offers decent quality products at reasonable prices. 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.
