The FSP Epsilon 600W is a quad-rail (+12V) PSU that supports SLI and CrossFire via dual 6-pin PEG connectors, just like the Cooler Master, and has support for mainboards with EPS connectors (most commonly required for high-end consumer and workstation board, and servers), again just like the Cooler Master. We see a split EATX connector again, and all main +12V rails are generously specified in terms of current draw.

Cable runs are sensible (grouped SATA again) and suited to the common chassis configurations we can think of. The unit supports enough current draw on the PEG rails for the next gen. of graphics boards and the universal input voltage means you don't have to worry about buying a particular variant for the country you live in.

A single 120mm fan takes care of the heat from the unit, and cable runs are mostly braided from end-to-end, meaning we'd like to see FSP do a bit better in that respect. FSP claims high efficiency at high loads, which we test, and the blue metallic finish is bound to appeal aesthetically to some, if not your copy writer.

The bundle is minimal, comprising only power cord, screws and manual, and the box art won't win any style prizes. Seems decent on paper and just out of the box.
