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 are lower than that of the Enermax MaxREVO power supply, we 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.
The above tests represent typical loads that we have measured from various systems and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different and actual loads can vary greatly even with similar hardware.
Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rails, we see 2% regulation from start to finish on all rails. 12V2 and 12V3 both showed the largest drop of .22V from start to finish while 12V1 and 12V4 both showed the smallest drop of .11V from start to finish. The 5V rail managed to stay within 1% of specification with a total drop of .06V from start to finish. Moving towards the 3.3V rail, we see that regulation crept up to 3% with a total voltage drop of .10V.
DC Output quality for the MaxREVO 1500W was just what we expected and well within specification. During Test 1, we saw 11mV of noise on our scope. When we increased the loads in Test 3, the ripple climbed to 20mV at a little over half load. During Test 6, the MaxREVO 1500W showed us a maximum of 29mV of noise at a 1000W load.
The MaxREVO 1500W rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87%/90%/87% efficiency at 20%/50%/100% loads respectively. As you can see, the MaxREVO 1500W passed on our bench wasn't close to failing at any point.
The MaxREVO 1500W exhibited zero signs during testing that it would have failed any of our tests if we were able to fully load down the unit to 1500W. We are confident that it would have continued giving us impressive results through full load.
Time and time again, Enermax delivers quality power supplies and today is no different. The Enermax MaxREVO 1500W power supply is a welcome addition to the lineup and one that is much needed to continue to provide enthusiasts with solutions to the massive requirements of today's very high-end PC market. Enermax knows that when such high amounts of power are needed, it is quite necessary that it be of quality and that is just what you get with the MaxREVO 1500W.
Since the MaxREVO 1500W is nearly identical to that of the MaxREVO 1350W, we expected that our performance numbers would be nearly identical as well. We were quite pleased when we saw mild improvements in voltage regulation. All of the 12V rails were still within 2% of specification and the 5V rail was still within 1%. Our 1500W unit showed that the 3.3V rail was now within 3% of specification and very close to being within 2%. DC output quality and efficiency were once again almost identical to what we saw with the 1350W model and we're happy to see that.
Where the MaxREVO 1500W really starts to shine is when you start to look at the price. There are only two power supplies on the market that are 1500W or more and priced lower than the MaxREVO 1500W. Of those two, only the LEPA G1600-MA is 80 PLUS Gold rated or higher. It too is manufactured by Enermax and is based off the design of the MaxREVO series. Making the deal even sweeter is that the MaxREVO 1500W is cheaper than many other manufacturers' 1200W-1400W units. Don't forget that Enermax backs your purchase by a five year warranty too.
It is nice to see that Enermax is not only providing some of the best quality power supplies on the market, but they are doing so while keeping the price in check. Keep up the good work Enermax!
