Enermax PSU REVOLUTION85+ 920W ERV920EWT

It is all about efficiency, so goes the public mind. But being 85+ efficient was the minimum goal for our engineers. We wanted to create the best PSU series in any regard and to have a worthy successor to our 1kW-class defining GALAXY & GALAXY DXX series’. By making REVOLUTION 85+ as the world’s first PSU to be FUTURE CPU ready! & FUTURE GPU ready!, we have achieved it!

REVOLUTION85+ is the first of the next generation of PSU design devastating the complete competition offering the highest efficiency available combined with the most connectors and versatility and the most comprehensive design and component selection to likely power the most demanding systems of today and tommorrow.

HardOCP is as impressed:

“… the Revolution that occurred in Enermax' top tier products really is change you can believe in. … The Revolution is not only an extremely good PSU, it is also a toss-up as to what its marquee feature is between its DC Output Quality and its efficiency. The Enermax Revolution 1050W is quite simply what product evolution should be and leaves us wondering just one thing. What rabbit is Enermax going to pull out of the hat for its next power supply?”
