Seasonic are using a 7 blade, 120mm JAMICON Dual Ball Bearing Brushless Fan, 12V 0.35A (Model KF1225B1HR-R) in the S12G-450 power supply. These are reasonably high quality fans.

The build quality is excellent and the overall design is very similar to the G Series units we have tested in the past. Obviously there is no modular PCB on one side of the chassis. Soldering quality on the main PCB is also at a very high standard.

The non modular cables run into the chassis and are tied down in several places to protect them against fraying.

Filtering starts with an X cap, four Y caps and a coil. On the main board is a TVS diode, two Y caps, an X cap and two coils.
