Enermax Galaxy EVO 1250W Power Supply

When we buy new PSUs for ourselves here at HardOCP, a company that always makes our short list is Enermax. Its build quality and performance has been topnotch for years. Today we put its 1.25 kilowatt computer power supply to the test. Crash and burn or continue to shine brightly?

Introduction

Enermax Technology Corporation is a company that is well known in the world of power supplies and general computing alike. Founded in 1990 Enermax has made a name for itself by providing solid performing power supplies, among other computer components, and accessories. Enermax' current lines of power supplies encompass a wide range of products targeted at various market segments including the MODU82+, PRO82+, Liberty Eco, Infiniti, Tomahawk, ECO80+, Revolution 85+, and Galaxy EVO.

In addition to being a retail presence with its Enermax brand power supplies, Enermax Technology Corporation appears to be one of the few real OEM designers of power supplies. Their power supplies however, have only rarely shown up under other labels including Grow Up Japan and Sapphire. For the most part Enermax appears to be a factory to retail presence with their own discreet lines of power supplies including today’s Galaxy EVO 1250W (EGX1250EWT-01).

In a Galaxy Far, Far, Away...

Today we see Enermax striking back as we are reviewing the second unit from them to carry the Galaxy moniker. This unit however, ads the catchy EVO tag and bumps the output capacity up to 1250 watt from the previous 1000 watts Galaxy DXX we reviewed a couple of years ago. In the gap between Galaxy episodes what has changed with the Galaxy line to earn that new EVO designation?

GALAXY EVO 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 tomorrow.

It is all about efficiency, so goes the public mind. But being 82+ 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 GALAXY EVO as the world’s first PSU to be FUTURE CPU ready! & FUTURE GPU ready!, we have achieved it!

Normally, nobody can dare to claim such, but we can, because we have implemented all necessary for the future: Four 12p sockets for possible connector changes & six massive 12V rails of 30A each for perfect load distribution and flexibility, no matter what is coming up. Besides complying already to the upcoming EPS12V PSU Design Guide, especially the ZERO LOAD Design assures compatibility. By needing no load at all, we can anticipate to have no issues at all with any new CPU or GPU or their features like C6 state or Hybrid Modes.

Let's move on to see what we have to look forward to when we purchase the Enermax Galaxy EVO 1250W in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
