Seasonic are using a high grade Sanyo Denki San Ace fan – the same model is installed in the 850W version of the unit (9S1212F404). This fan uses dual ball bearings to enhance life span and reliability. It is constructed around 7 blades which are sculpted to reduce noise while maintaining a high level of airflow.

This supply uses only a couple of heatsinks, however with the 80 Plus Gold Efficiency rating and the large fan overhead it should be fine.

As we noted before, Seasonic are not skimping on the quality of the components in this system. Japanese capacitors are used throughout, with the primary stage using two Nippon Chemi Con caps, rated 420v 330 uF @ 105c.

The design of this unit replaces traditional wired connections with direct pin to port connections. This reduces the heat generated by the wiring which has the subsequent benefit of reducing lost power, ensuring improved voltage. The unit includes Total Power Protection (OPP), Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP).
