Enermax Revolution 85+ 1020W Power Supply Review

Rating: 8.5.

Every enthusiast knows the Revolution 85+ series of Power Supplies from Enermax, they have been winning awards across the globe for many years. With a lethal combination of performance and efficiency the original 1250W Revolution 85+ powered many of our high end review systems across a 2 year time period.

Enermax have decided to revisit the Revolution 85+ series with two new models, the ERV920EWT/ ERV1020EWT (920,1020 watt respectively). What is most interesting however is that Enermax have dropped the prices with a new compact PCB design taking centerstage. The old 950W model for instance retailed at 295 euros and the new 920W is selling for 260 euros.

The model we are looking at today is the 1020W which is set to replace the 1050W model in the previous range. The only unit to survive the ‘changeover' will be the 1250W high end model. All of the new models have also received a fan change, with one of the new Twister fans replacing the old ball bearing units. We have looked at some of the new Enermax fans in the past, and they are very good – check out the review over here.
