Under the Hood
Here are a few pictures showing the layout and components inside the Enermax Revolution85+ 1,050W power supply. The overall layout, build quality and component selection appears to be very good, just as we would expect from Enermax.
On the primary side we find three high-quality Mitsushita capacitors, which are rated for 220uF, 400V and 85°C along with a large PFC choke coil and the dual primary bridge rectifiers with a small aluminum heatsink sandwiched between them.
One of the innovative features incorporated into the new Revolution85+ design is what Enermax calls their Asymmetric Hybrid DC-to-DC topology. One of the key components is an imbedded circuit that synchronizes the load between the two primary transformers.
The Revolution85+ power supply uses two DC to DC converters (on the backside of the modular interface board) to produce +3.3V and +5V from the main +12V section. Enermax uses six solid polymer caps back here; very nice.
Over on the secondary side you will find a lot of Nippon Chemi-con caps buried underneath all the distribution wiring.
