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.

Why People Like You Chose Powermax
BIG kudos to your company for shipping to APOs. I love Apple and all their products, but their lack of support to Service Members deployed and stationed overseas has been a sore point with me for a long time!!! It is refreshing to find a company that understands that Soldiers in Iraq (and Afghanistan, and Germany, and Japan, etc.) deserve easy access to Macs as well as anyone else.
Thank you for your help.
I'm VERY happy with the iMac I purchased from you, and I would definitely say this is the best support I've had. I also want to thank you for PowerMax's support of the military by shipping Apple products to APO addresses. Thanks again, and I look forward to getting another Mac from you soon!
Thank You,
Thanks for all the information, it is a great help. I will let you know how it all comes out - and may have to ask you for some more help. I appreciate your consideration - actually this is the way I have been treated by everyone I have worked with at PowerMax. I wouldn't buy a Mac anyplace else. This is my second one from PowerMax.
Take care,
I thank you and PowerMax for the always terrific service. I must always remember to check with you guys first.
Thanks,
I would like to thank you for the prompt response to the drive situation. I received the drive on Wednesday afternoon, installed it on Thursday and everything went as smooth as could be. My experience with PowerMax has been a pleasant one, and I am looking forward to doing business again in the future. Once again thank you for all of your help.
Thanks,
