Seasonic are using a 135mm Hong Hua Fan, marked HA13525H12F-Z. This brand feature in all of the Seasonic power supplies we have tested in the last 1-2 years. It is an excellent Fluid Dynamic bearing fan with a long life span and relatively low noise output If kept below 2,000 rpm. It is rated 0.50A 12VDC with a maximum rotational speed of 2,300 rpm.

Seasonic have a small plastic panel attached over the fan (see above) to specifically direct air flow to the components underneath. Incidentally you can buy these fans directly from ASIA for around $25, so its a relatively expensive unit. We have even seen them listed on EBAY lately (HERE). The fan is rated to a 100,000 hours mean time before failure @ 25c.

Seasonic don't rely on any OEM partner for their designs. All their units are created in house. Sometimes you will find Seasonic designs in other companies power supplies such as Corsair, ASUS and Phanteks.

The primary stage of this design adopts two 105c rated capacitors from Nippon Chemi Con (KMR) and Nichicon – two very highly regarded Japanese brands.They are rated 560uf and 330uf respectively for a total output of 890uf. The secondary stage also features high grade Japanese capacitors.

The unit offers OPP, OVP, UVP, OCP, OTP and SCP protections.
