Test Results

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 higher than that of the Enermax Platimax 600W, we can test it to the maximum.

One of the strongest areas of Enermax power supplies has always been their spectacular voltage regulation. Our Platimax unit didn't disappoint on this front and managed to keep all of the rails within 2% of specifications with the exception of the 3.3V rail. The 3.3V rail started off at 3.37V which pushes it just barely into the 3% regulation range.

We were a bit worried when we started looking at the DC Output quality of the Platimax 600W as it started off somewhat higher than what we are used to seeing during the first test at 21mV. Our worries were quickly put to rest as we increased the loads to Test 2. The ripple seen on the scope barely changed and it increased to 24mV.

As we increased the loads even more to Test 3, we saw another marginal increase in noise up to 28mV. Once we fully loaded down the unit we were happy to see that there was still less than 30mV of noise on the 12V rail. The Platimax 600W power supply displayed one of the best noise deltas from start to finish that we have ever seen.

The Enermax Platimax 600W carries an 80Plus Platinum certification with it. This means that it must be 90%/92%/89% efficient at 20%/50%/100% loads respectively. Things started off great during the first test and the unit wasn't even close to being on the bubble. Test 2 shows that the unit was right on par with where it should be, but efficiency started dropping right after that. During the full load test we see that while the unit was passing, it was starting to cut it a little bit close.

Final Thoughts

Enermax has done a fantastic job with the Platimax 600W unit. We've tried to find things to complain about, but there just wasn't anything that stood out. Performance was fantastic from the unit as the voltage regulation was great and the efficiency numbers held up from start to finish. The power supply even had some of the most stable ripples we have ever seen from start to full load. It has a full set of features to make almost any enthusiast happy, looks great and is backed by a five year warranty.

About the only thing many will complain about is that the unit will come to market with a very hefty price tag for a 600W power supply. Enermax units have always had a little bit of a price premium and it is all the reasons listed above that make their units worth the extra cash. Add in that this is an 80Plus Platinum unit and the efficiency coupled with the ever increasing costs of electricity and this unit will likely pay for itself rather quickly.

You'll definitely want to make sure you keep the Platimax 600W unit in mind if you are going to be in the market for a 600W PSU in the next few months.
