FSP Epsilon 700w ATX PSU



The Epsilon 700w is a great looking power supply which breaks away from the plain black power supplies which saturate the market. Despite the unit producing some very strange results on our PSU tester, it managed to easily power our test pc and keep all rails well within ATX specifications.

The good performance coupled with the excellent efficiency of this unit makes it a great choice for those of us who want to power a high end pc whilst also keeping their electricity bills low.

Selling for £105 over at SpecialTech, the Epsilon is priced very competitively against other 700/750w power supplies on the market and is definitely worth checking out for Crossfire and SLI users.

+ Metallic paint finish
+ Good rails when tested on PC
+ Very high efficiency
+ Adjustable pots
+ Plenty of connectors
+ Rail layout suitable for Crossfire/SLI

- Exhibited strange behaviour when placed on our PSU tester
- Could be quieter under heavy load
- Poor internal cooling solution


Thanks to FSP Group for providing this unit for review.

Looks a decent, solid, if not a little strange acting PSU Quote

Yeah it threw a bit of a 'hissy fit' on our load tester, but managed to do pretty well when plugged into the test rig.Quote

Whats EPS stand for?Quote

Glad it started working for you correctly mate! FSP usually makes a great unit. My blue storm was the heaviest and most solid psu I'd ever had for the price I paid for it.Quote

the hiper uses the same connectors. Just out of curiosity, will you have various charts/graph diagrams comparing all the psus you've reviewed?Quote

05-07-2006, 07:26:34


Yes, once we've got a few more manufacturers on board, i will create a comparison chart so we can truly see what PSU takes the crown Quote

You gotta get a Tagan 1100w to review. Now that'd prolly take the crown *drool* Quad SLi connectors are so sweet, especially the way Topower sleeves them. Topower makes most of the OCZ PSU's, Tagan PSU's, and I think the Mushkin PSU's too... gotta check tho.

Ya, Mushkin's is Topower made to Mushkin's specs.

A funny little note is that OCZ's newer Gamestream PSU's are the FSP Epsilons Quote
