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 SGALAXY & SGALAXY DXX series’. By making SGALAXY 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.

SGALAXY 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.

[VIDEO REVIEW]
"The SGALAXY EVO line of power supplies are currently available in wattages ranging from 850 to 1250. The Enermax SGALAXY EVO 1250W Power Supply is the flagship in the line and it will easily power the most extreme systems out there. The approximate maximum peek output of the 3.3/5v rail is 170 watts & the 12v is 1248 watts. The +3.3V & +5V rails are both 25A each. There are six +12V rails 30A each, with a combined power of 104A. With performance, efficiency, good looks and a quiet135mm fan, what's not to like! Watch the video to find out more..."

	The Enermax SGALAXY EVO 1250W is a behemoth of a power supply in just about every conceivable manner of criteria: it's strong, durable, and attractive. It can handle anything you can throw at it and will provide rock solid stability and power for your precious system. The EVO doesn't come cheap, but in return you get one of the very best power supplies on the market.
	The Enermax SGALAXY EVO 1,250W PSU delivered good voltage regulation (especially on the important +12V rails) with relatively clean outputs and good efficiency. The EVO 1,250W PSU is quiet, runs cool during normal operation, and includes an excellent compliment of both fixed and modular cables/connectors.
	Overall the build quality of the SGALAXY EVO 1250W is identical to the Revloution 1050W that proceeded it and it is very good again today. Through this review and build quality section we have commented on how the SGALAXY EVO 1250W is the same as the Revolution 1050W and the reason we have is that they are the same units in general.
	Enermax took what was already a spectacular platform and made it more spectacular with the SGALAXY EVO 1250W. This will be the only model in this line to be sold in North America, as Enermax intends it to be the top end to the Revolution 85+ line on this continent.
