Enermax Revolution 85+ PSU to have a high efficiency

Posted on Friday, August 22 2008 @ 23:51:49 CEST by

Enermax is getting ready to roll out their new Revolution 85+ power supplies. AnandTech received a 1050W pre-production model and published some photos of this new model. The PSU features six 12V rails with a rating of up to 30A per rail and the reporter says the PSU reaches up to 90% efficiency with a 230VAC input!
Coming soon to the market, and announcing today at AnandTech, Enermax is introducing their new Revolution 85+ series. We already have our hands on a 1050W pre-production model, and we were surprised with the direction Enermax has taken. Looking at the specs, we see six 12V rails with each… nothing unusual, except here each is rated at up to 30A. The 3.3V and 5V rails will come from VRMs as we have seen recently with some other power supplies, which is a very good development in the market. Why pull all of the lower rails out of one transformer when you can just generate the lower voltage rails later via VRMs?

The Revolution 85+ will be available in 850W, 950W, 1050W, and 1250W, though the last is slated to only be available in Europe with support for 230VAC. Efficiency wise we have seen the highest results to date at AnandTech. With a 230VAC input, the power supply reaches up to 90% efficiency, and this might even be topped by the 850W or 950W models. Regardless, the efficiency stayed above 86% throughout operation. The cable management has jacks for up to ten extra cable harnesses, with four 12-pin jacks for the four 6/8-pin PEG connectors. Enermax has included 12-pin jacks since the Modu/Pro82+ to provide for compatibility with future requirements.
