Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.
The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits lower than that of the MaxRevo 1350W, we can only test it to 1000W.
Our test equipment is also only capable of loading down four rails simultaneously. As a result of these limitations, our test results for 12V3 represent a shared load for both the 12V3 and 12V4 rails and the test results for 12V4 represent a shared load for both the 12V5 and 12V6.
Voltage regulation fared rather well with the Enermax MaxRevo 1350W power supply. All of the 12V readings were within 2% of specifications. The 5V rail managed to maintain 1% regulation, but the 3.3V rail ran a little bit on the high side. Even so, it was never any worse than within 4% specs and came closer as the loads increased.
DC output quality was good throughout all of our tests. Starting out with Test 1, we saw a 12mV ripple on the scope. At about 50% load we were sitting at 21mV of noise on the 12V rail. Increasing the load to the maximum of our test equipment showed a 27mV peak to peak ripple. While this isn't the most spectacular DC output quality that we've seen, it is still impressive considering the heavy load placed on the power supply and that it still has plenty more power to provide if asked of it.
After reading the 1% to Platinum and up to 94% efficiency claim on the box, we had hoped that the MaxRevo 1350W power supply would have boasted a little bit higher efficiency numbers than it did. Even so, the unit still deserves the 80Plus Gold certification it bears. This alone is impressive considering the total output of the power supply.
While we don't have the equipment to test the Enermax MaxRevo 1350W to the limit, there are several conclusions that it is safe to say about the MaxRevo1350. Given the results that are shown above, there is no reason that the Enermax MaxRevo would have failed any of our tests. The results shown above are all well within specifications.
Enermax has proven itself once again as a trusted name amongst enthusiasts. As one of the highest output power supplies that we have tested to date, the Enermax MaxRevo 1350W does quite well across the board. When you take into consideration the massive loads that this unit is capable of supporting, you realize that you are going to give a little to take a lot.
The MaxRevo 1350W unit that we reviewed sacrificed a little bit of voltage regulation, but gained so much from doing so. Efficiency was phenomenal for such a high output unit and perhaps the best we've seen to date out of 1kW+ power supplies. DC output quality was also great when you look at how much power you are getting out of the unit. Topping everything off is the excellent build quality the unit shows inside and out.
Those looking for more than 1200W of power will be extremely pleased with what the Enermax MaxRevo 1350W power supply has to offer, especially since it is priced right with several 1200W units.
