The fresh Enermax MAXREVO 1500 W is undoubtedly a very good PSU from a company with a long and successful tradition in this field. Since the EVGA SuperNOVA costs significantly more, it only encounters competition from its own siblings, the LEPA 1600 W and the Enermax Platimax 1500 W. Both the above-mentioned LEPA and Enermax units registered looser voltage regulation on the +12V rail than the big MAXREVO, but come with ten PCIe connectors out of the box. The LEPA unit also costs around 30 bucks less; however, the LEPA doesn't include as rich of a bundle as Enermax's units. I would, personally, pick the EMR1500EGT over its in-house competition because it managed to attain decent voltage regulation at +12V with a full load and 47°C ambient. Its ripple suppression on the same rail is, furthermore, quite good. Overall, the MAXREVO 1500 W is a high quality PSU that delivers tremendous power levels only very few systems with multiple and highly overclocked Graphics Cards and CPU(s) will fully utilize. One positive aspects of this platform is the fact that it is able to attain high efficiency at bottom low loads far smaller than 10% of its maximum rated capacity. The big MAXREVO actually performs really well and doesn't waste much energy in an area, here efficiency at low loads, other high capacity PSUs struggle with. A user that invests in such a high capacity PSU usually won't utilize it with a system that stays at idle for significant periods of time, but a high efficiency at low loads from such a monster is, nevertheless, impressive.
To wrap up, the price of the Enermax MAXREVO 1500 W looks intimidating for sure, but you should definitely add this unit to your list of candidates if you plan to install multiple Graphics Cards into your system and need a highly reliable PSU with solid performance numbers. You see, the purchase of a PSU is actually an investment because it will accompany you for many years to both feed and protect all your other precious hardware.
