Small Form Factor (SFX) PSU review: power supplies for small PCs

Seasonic SS-300SFD 300W

The Seasonic SS-300SFD also has a capacity of 300 watts. The design of it is a little different, as the fan protrudes somewhat. You therefore need to make sure it will fit in the chassis that you want to use. The PSU also has two 12 V rails, that can supply a total of 22.5A.

You get two molex and two SATA connectors, and like the FSP only a single 4-pin CPU connector. There's also an 8 cm fan and the cable also aren't sleeved. The average price is £33.
