FSP Epsilon Series 80PLUS SLI (700w)

The FSP Epsilon 80plus 700W is immediately distinguishable from the competition, thanks to its metallic blue finish and transparent 120mm cooling fan, through which the internal PSU components can be seen.

This FSP Epsilon 80plus 700W's fan is thermostatically controlled and will turn off completely when the power output is sufficiently low. As things heat up, the fan will spin into action, but remains reasonably quiet.

Curiously, a pulsing sound is emitted as the FSP Epsilon 80plus 700W's fan starts up, but this stops once it's up and running.

As its name suggests, the FSP Epsilon 80plus 700W PSU achieves standard 80plus certification which we confirmed through our own measurement process.
