Seasonic TFX 350W PSU Review


DSCF5823
The Seasonic TFX 350W uses an 80mm ADDA fan (Model number AD0812MB-D90). This is rated for 3,500 rpm and 40dBA. We would hope it won't ever be running at full speed. Its not the highest grade fan for a unit like this and I would expect a little more from Seasonic to be perfectly honest.

As this is a TFX supply, the arrangement inside is a little unusual. There are small aluminum heatsinks scattered across the PCB. The unit features a second horizontal PCB which sits above the main PCB. The design of the unit is a LLC resonant primary and a synchronous rectification with DC-DC VRM's secondary.

The soldering quality is high and we didn't notice any issues worth mentioning. Seasonic are using a 105c Hitachi Japanese primary capacitor rated 220uF, 420V. Secondary capacitors are Nippon Chemi Con.

Input filtering begins on the PCB attached to the input receptacle with X and Y capacitors and a coil. This continues to the main PCB. Behind the filtering components we can see a small heatsink which has the bridge rectifier attached to it. Another heatsink on the edge of the PCB is home to the PFC power components.

The PCB on top is home to the DC-DC VRM's. These VRM's incorporate Nippon Chemi Con Capacitors. Under this PCB there are more Japanese capacitors.
