Enermax Revolution87+ 850W PSU Review

Enermax is the oldest and most well-known designer and manufacturer of high performance power supplies for commercial use, a favorite of hardcore enthusiasts for decades. Unlike most other companies, the power supplies of Enermax do not come from an OEM but the company designs and manufactures their own products, making their units unique. Today we will be testing a power supply based on one of their better designs, a high performance 80Plus Gold certified modular design, the Revolution87+ 850W unit.  

Enermax is the oldest and most well-known designer and manufacturer of high performance power supplies for commercial use, a favorite of hardcore enthusiasts for decades.

Today we will be testing a power supply based on one of their better designs, a high performance 80Plus Gold certified modular design, the Revolution87+ 850W unit.  

The company first started back in the early 90's, when there was little to no competition in the high performance power supply market. Today however, even though the market has vastly expanded since then, there also are tens of companies offering hundreds of high performance units. We counted no less than eight 850W 80Plus Gold certified units while browsing a single large shop alone, meaning that the Revolution87+ 850W power supply is facing some serious competition. We will see just how competitive of a product it may be in this review.
