Output Specifications

Some might decry the use of multiple +12V rails on this power supply but as we have been saying for years now: if multiple rails are set up properly, they can provide all the functionality of a single rail design. Enermax has done just that with six +12V rails which are each rated for a whopping 30A (360W). To put this into perspective, you would safely be able to run TWO stock HD 4870 cards off each rail of the Revolution 85+ 1050W.

The connectors themselves are brilliantly laid out in relation to the rails as well. The two CPU connectors and the ATX 24-pin cable share the +12V1 and +12V2 rails ensuring that this unit can easily power any dual CPU system on the market. Meanwhile, the two non-modular PCI-E 8-pin connectors share the +12V3 rail.

When it comes to the modular cables, things get a little more complicated. Two of the modular interfaceís PCI-E connectors are linked to the +12V5 railís 30A which means up to four PCI-E 8-pin connectors can be connected to this rail. At the same time, the other two PCI-E interfaces are each given a rail (+12V4 & +12V6) to share with the Molex / SATA cables.

The +5V and +3.3V rails get a good allotment as well but the main focus is of course on the all-important +12V power.

All in all, we feel that this is a perfect rail layout especially with 99.9% of the Revolutionís power being available on the +12V rails.
