Efficiency and Power Factor

The Enermax Revolution 85+ sets a new record as it is the first power supply tested in our labs to exceed 90% efficiency! I guess this is largely due to the above-described synchronous rectifier. The Revolution 85+ is the first PSU with a synchronous rectifier in the main transformer that I have ever tested.

As opposed to most competitor products, the standby source of the Revolution 85+ has a load capacity of 5A. It does its job well: the output voltage is 4.87V at full load, the allowable minimum being 4.75V.

Summary

I won’t say if it is revolution or evolution, but Enermax’s engineers have indeed come up with something new and original from a technical standpoint. This PSU is original not only with its exterior but also with its interior design. The capabilities of the Revolution 85+ may seem even redundant for today – the number of unused connectors for detachable cables is a clear indication of that. However, people at Enermax stress the point that they have tried to create a platform not only for today but also for near future, stuffing it with everything best that modern electronics can offer. And they seem to have succeeded.

Besides the moral satisfaction of owning one of the most technically sophisticated power supplies, the Enermax Revolution 85+ offers you good quality of manufacture, excellent electric parameters, a rich selection of cables and connectors, and quiet operation throughout the entire load range, up to the maximum 850W.

As you may have guessed, the biggest downside of this product is its price. The recommended price is $309 or €229 taxes excluded.
