Enermax Platimax 850 Watt Power Supply

Enermax PlatimaxJust a couple of weeks ago we took at one of the best and largest power supplies we have seen here at Pro-Clockers. It was from Enermax and boasted 1350 watts of pure power and was called the MaxRevo. That particular unit was aimed at the end user needing tremendous amounts of stable power. But Enermax is at it again yet with another power supply that is a little more refined than the MaxRevo, but sporting quite a bit less power. The Platimax is based on the highly efficient 80PLUS Platinum rating which requires the power supplies to maintain 90% efficiency at 20% load, 92% @ 50% load and 89% @ 100% load.

Closer look

First off, we need to get some details out of the way that cannot be stated obviously just by looking at the unit. We stated in the introduction that it has a Platinum efficiency rating which is the highest at the present. But Enermax is more than about meeting standards by going beyond them. The Platimax has four members in the family which would not only be the 850W model we are testing today but a 750W, 1050W and a massive 1200W unit. All of which supports multiple-GPU setups with the aid of atleast four PCIe connections.

Adding needed under- and over-load protections to a power supply is nothing new but in the class of the Platimax series Enermax implemented SSI precautious to unit to make them also suitable of servers and workstations. 

Visually, we look what we see from the Platimax as it sports a very nice and stylish textured shell just like what we saw from the MaxRevo. It seems as Enermax wanted to take a new approach to your PSU offering and this approach is a winner. No fingerprints are left behind after manhandling it nor is it easily scratched.

To cool the Platimax an Enermax Twister fan is used. The fan measures 14cm and blows over the entirety of the power supply’s internals. The fan is also controlled via a PWM module and features HeatGuard which will allow the power supply’s fan to continue to run several second after the system has been shut down, usually about 30 to 60 seconds afterwards.

Honeycomb openings are what allow the heat produced by the unit to escape out of the rear. He Platimax is also ready to be used anywhere in the world as it supports 100- 240VAC.

The Platimax uses a series of red and black sockets for the connectivity of the modular cables. There is a small diagram underneath that will tell you just what leg goes where.

Results

We know that testing a power supply on a loaded system is not the very best way to do so, but you can not overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multimeter. Those sites and the methods they use should be the true means of determining how good a power supply really is; however, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.


Conclusion

The Platimax is the first platinum rated power supply we have ever tested and we are happy it is a model from Enermax. For the past few years, we have seen Enermax produce some of the most powerful, highly efficient and most stable power units on the market. And the Platimax definitely does live up to that well deserved reputation. Able to provide the user with above 89% efficiency throughout the load operating range you can’t go wrong as it helps to keep the electricity bill down while providing clean and stable power. And not only that the HeatGuard helps to maintain the life of the unit with its ability to keep the fan running after shutdown to allow the dedicate internal components to cool down properly.

The Enermax Platimax 850W goes for about $225 on most reliable online stores. This makes the unit a little on the expensive side. But one must remember you are paying for a good power supply with a very good efficiency rating.
