The unit (as expected) uses a Hong Hua fan – the HA13525H12F-Z in particular. This is a high quality FDB fan (Fluid Dynamic Bearing) fan rated 0.50A, 12VDC. These fans can be bought for around £15 online now – a quality fan, rated to 2,300rpm maximum rotation.
This is a full bridge topology design based on the Seasonic Vertex PX Platinum platform. This specific unit is similar to the VERTEX PX ATX 3.0, with the primary difference being the new 12V-2×6 connector/cable. An LLC resonant converter is adopted for lossless switching and improved efficiency levels. The 12V powers a pair of DC-DC converters to generate the minor rails. The power supply is well designed, to be able to allow air to flow through the components. Heatsinks are quite small, but due to the high rated levels of Platinum efficiency there should be no concerns.
This unit is populated with quality 105c rated Japanese capacitors from Rubycon, Nippon Chemi Con and Nichicon. The two primary Nippon Chemi Con capacitors are rated 330uF and 560uF to produce a total of 890uF. Seasonic have adopted an array of polymer and electrolytic capacitors on the modular PCB to help with ripple suppression.
Overall, a very well made, quality design with excellent soldering across the boards.
