FSP's Epsilon 80plus 700W is a capable PC PSU (power supply unit).
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.
We measured an efficiency of between 81 and 82 percent up to the rated power output of the FSP Epsilon 80plus 700W which it managed to maintain up to 50W beyond its specification. It also maintained excellent 12v output from its four rails right up to 750W.
The FSP Epsilon 80plus 700W's SLI certification allows you to attach a pair of graphics cards for top performance via one 6pin and one 6+2pin PCI-Express connector.
FSPs power supplies come in different versions, the Everest range comes with modular cables whereas the Epsilon range, reviewed here, does not.
