Alright so let's talk a little bit about what this PSU ahs to offer. Enermax is known and reputed by their higher-class power supplies. Especially the more high-end series -- kick total ass. This translates itself into the most stable and ripple free power supplies. This is the marketing induced feature set as provided by Enremax:

Yes that's absolutely stuffed full with features. This PSU is released in 850W, 950W, 1,050W, and 1,250W models, Enermax wanted us show you what they have to offer. And sure, as such it is only fair that we took a look at of the finest PSUs but - we check out the 850W model - targeted at the enthusiast PC builder out there with a demand for heavy graphic cards.
I say this as the PSU will come with six .. that's right six separate 12V rails each allowing a 30 AMP peak (though combined 70A) and that's a lot. Do some simple math with me here, 70A x 12V = 840 Watt available on the 12V lines for all the graphics havoc you like to create. Then another 160W is available on the +3.3 and +5V rails and a little extra on the 5V Vsb and -12V rail totalling everything up at 1032 Watt.
Now you are going 'huh more than a 1000 watt ?' right now. Yes, that's Enermax, the PSU is classified at 850 Watt, but really can easily handle much more, even over a kilowatt. And that's value right there in your pocket.
The PSU is labelled with a Silver class power energy efficiency, what that tells us is that the PSU efficiency is exceptional for a PSU the 850 Watt range -- ranging from 85% to 91% over a wide range of load utilization.
The unit is kept cool by a 13.5cm fan spinning at a maximum of 1,500 rpm at full load. However we feel even with the PSU stressed that 1500 RPM is never reached, so 1000 RPM on average seems a more plausible number making it a very silent product.

Enermax Liqtech 120X and 240 review We test and review the all new Enermax Liqtech 120X and 240 Liquid coolers. Can it keep up with similar Asetek and compeeting products? Let's find out!...
Enermax Fulmo GT review We review and test the Fulmo GT. Enermax has been going very strong with their power supply and fans. For a while now they also offer PC cases, and more recently they released what seems to be the biggest chassis I've ever laid my hands on. This chassis series has HPTX support for the bigger than biggest motherboards and some pretty cool features as well.
Enermax KW001 Briskie Keyboard mouse combo review Keyboard kits come in all sizes, shapes and forms .. and that's next to a gazillion of manufacturers that offers them. Surprisingly enough a few weeks ago Enermax, the guys behind the best power supplies and the brightest fans also launched a keyboard/mouse combo. Briskie is all about value and as such for 25 USD/EUR you get a mouse and what we think is a very decent wireless RF keyboard.
Enermax Platimax 850W power supply review Enermax always is able surprise us, they now have released the Platimax power supplies, that means a platinum certification and yeah .. that boils down to a 94% efficient product. Very few products get this certification. Today we'll grab a couple of older older supplies and see if what they claim is true, can we really save on energy. We fire off three PSU's at a P55 / Core i7 870 based system setup with a GeForce GTX 590. We then monitor power consumption in idle, CPU productivity (stress) mode and then lock into a gaming session.
