The EPSPOW750PRO achieves 80% energy efficiency or greater at 20%, 50%, and 100% load. This is primarily due to the Active Power Factory Correction, which improves voltage stability. Despite being a powerful unit, it provides environmentally friendly power usage. The unit meets the 80PLUS certification standard for higher efficiency power supplies. 80% efficiency refers to the feature that 80% of the power the unit draws from the power grid is turned into usable power. Or in mathematical terms, DC Watts divided by AC Watts.
As we mentioned previously, the EPSPOW750PRO has Quad 12v rails, providing dedicated voltage outputs. The unit has a total of four 6-pin PCI-Express power connectors, but this isn't necessarily meant to power a Quad-SLI system. These are provided so no single rail overdraws on power. The EPSPOW750PRO is, however, fully SLI capable.
The EPSPOW750PRO's enclosure is nickel-plated, giving it an anti-corrosive shell for all those dangerous lab experiments we're sure our readers put their rigs through. And as we mentioned earlier, the cables are sleeved in a nylon mesh for better neatness and airflow.
To get a better idea of unit's features, here's a list of the technical specifications:

Now that I've covered the important features and technical specifications of the unit, it's time to put this behemoth in to a case and wire it up to to our test system.
