The new Revolution85+ power supplies from Enermax were designed to deliver clean, stable outputs with high efficiency and minimal noise. The Revolution 85+ series comes in four different wattages: 850W, 950W, 1050W, and 1250W – although the last will only be available for 230VAC.
Revolution85+ power supplies are some of the first to be certified under the new 80 Plus Silver classification to be at least 85% efficient at 20% and 100% of the rated output and at least 88% efficient at 50% of the rated output power.


The feature list is impressive, with six 12V rails, no-load operation (which will be important for future hybrid power GPUs), power saving modes for upcoming CPUs, high efficiency, and all outputs rated at 50°C.

The six 12V rails are each rated at 30 amps, although Enermax has almost certainly set the OCP a little higher, i.e. 35 amps. There is more than enough power to connect the most demanding graphics cards, a highly overclocked processor, plenty of hard drives, and still have room to spare.
12V1 delivers power to the 24-pin ATX connector;
12V2 powers both the 4/8-pin and 8-pin EPS connectors;
12V3 is for the first and second graphics card connectors;
12V4 handles the first 12-pin socket and peripheral sockets 1, 2, and 3;
12V5 gets the second and third 12-pin sockets;
12V6 is for the fourth 12-pin socket and the remaining peripherals.

The distribution is very good and nobody should experience any overloads with today’s hardware. The 3.3V and 5V are both rated at only 25A, although this is still more than sufficient for modern systems. The standby 5V rail is stated at 5A, which is massive compared to many other power supplies, but it’s necessary in order to comply with the EPS12V regulations in version 2.92.
