"The High Power Direct12 BR 850W power supply seems to be internally identical to the Enermax NAXN 82+ 850 W. It can really deliver its labeled wattage at high temperatures, and it presented efficiency between 82.2% and 86% during our tests and very low noise and ripple levels. One of the highlights of this product is the cable configuration, with eight video card power connectors, allowing you to hook up to four high-end video cards, and 12 SATA power connectors."
