The Enermax NAXN 82+ 750 W is a very nice mainstream power supply that will meet the needs of the average user. Efficiency was high, ranging from 83.8% to 86.4% when pulled between 20% and 80% of the labeled wattage (i.e., between 150 W and 600 W), dropping to 81.7% at 750 W. Voltages were always inside the proper range, as were the noise and ripple levels. All this means that this is a safe power supply that won’t fry or overload your components.
Another highlight of the NAXN 750 W is that it allows you to buy an additional cable with two six/eight-pin connectors for video cards to make it compatible with three high-end video cards.
The main competitors for this unit are the Antec High Current Gamer (which is more expensive), the PC Power & Cooling Silencer Mk II 750 W (same price), and the XFX PRO 750 W (same price). The Enermax NAXN 750 W has an advantage against these other products having a modular cabling system. The XFX PRO 750 W has the advantage of lower noise and ripple levels, while the PC Power & Cooling Silencer Mk II 750 W, an 80 Plus Silver model, has the advantage of presenting higher efficiency. They are all good products, and the final decision of which unit to buy will depend on which of those features you think are more important.
