Enermax Revolution85+ 1250W promises 87-91 percent efficiency

Posted on Friday, November 07 2008 @ 15:14:29 CET by

Enermax unveiled its Revolution 85+ power supplies, this new series features 850W, 950, 1050W and 1250W models. The first three models have a 80 Plus Silver certification and the 1250W model promises to deliver an efficiency of 87-91% between 20-100% load!
It is all about efficiency, so goes the public mind. But Jimmy Song, ENERMAX’ director of R&D and co-founder, wanted more than simply the highest efficiency in the modular server/workstation class: “Being 85+ efficient was the minimum goal for our engineers. I wanted them to create the best PSU series in any regard and to have a worthy successor to our 1kW-class defining GALAXY & GALAXY DXX series’.

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.

This is all part of it’s “AHD2 Topology”. Asymmetric Hybrid DC to DC Topology means that we use multiple different technologies and concepts to maximize it’s performance by multiplying topology elements in differing exponentials compared to competition: QUAD FORWARD Circuitry, the main reason of our high efficiency, since everybody else is single or double forward. QUAD PFC, helps as well, again others are single or dual. TRIPLE AC + DUAL DC EMI Filter keep the current cleaner than others. > 20kìf secondary & even tertiary capacitors keep the output totally stable at all loads. A SYNC TRANSFORMER ARRAY renders overloading nearly impossible. And the good news is that we could squeeze all that with a single 135mm fan into 190mm length fitting into most mid towers, while still being 24/7 @ 50°C and ultra-silent.

The more “normal” features are our known PowerGuard status monitor, SafeGuard now with 8 protections instead of formerly six (SIP (Surge & Inrush Protection) and UVP now as separate AC UVP & DC UVP), AirGuard to reduce air turbulences and the new HeatGuard after shut-down cooling.
