Final Thoughts and Conclusions
The Seasonic SS-300TFX is an excellent TFX format power supply.  The PSU delivered very good voltage regulation with good efficiency and maintained clean outputs across a wide range of loads. If you are in the market for a solid 300W PSU for a Micro ATX Media Center or Home Theater PC, the Seasonic SS-300TFX deserves a very close look!

The Seasonic SS-300TFX power supply is currently available and sells for around $40~$50 USD.
