FSP Epsilon 700w ATX PSU

Appearance

The first thing that strikes you about the Epsilon 700w is its finish. Painted in metallic blue, the Epsilon sparkles under bright lights and makes me think what a great companion it would be for Coolermaster’s Wavemaster Blue case which has a very similar finish. The overall paint job is very good, but does not carry quite the same depth and shine of a cars bodywork.

Probably one of the smallest power supplies I’ve ever reviewed at 140x150x86mm, (LxWxD) I was surprised that FSP managed to fit such a powerful unit into such a small package. However, despite it’s small size the Epsilon did feel quite heavy, buy maybe not as heavy as some of the other small-sized atx units that I’ve reviewed in the past.

The back of the unit sports a honeycomb mesh for allowing air forced into the unit by the 120mm fan to exit out of your case. You may also notice that there is no 110/240v switch present on the back of the unit. This is because the Epsilon, like many other modern PSU’s is able to auto-detect the input voltage.

FSP have chosen to cool the unit with a single 120mm fan, which is covered by a silver fan grill. Many manufacturers choose this method of cooling, as it is much quieter and often more effective than using a smaller 80mm fan.

The front and sides of the unit are pretty plain, with a couple of small grills to aid in the cooling of some of the components inside.
