Introduction

We would like to thank Enermax for supplying the MaxRevo 1350 W review sample.

Till recently Enermax didn’t have a PSU in the Mega (>1000W) category with Gold efficiency, so Antec and Corsair dominated the field with the HCP-1200 and AX-1200 respectively, and enjoyed the loneliness of the top. However this is going to change with the Enermax MaxRevo series, which consists of three members with 1200, 1350 and 1500W capacities with the first two being Gold efficiency PSUs on steroids, since the manufacturer claims up to 94% efficiency. Although we heard numerous announcements at Computex 2011, actually it’s the first time that a manufacturer has a 1500W, high efficiency PSU ready to hit the shelves (at the time of the review the MaxRevo EMR1500EWT wasn't listed on the 80 PLUS site so we don't have an official statement about its efficiency rating). We admit that we would prefer the Enermax MaxRevo 1500W model for this review but we won’t say no of course to its smaller brother, the MaxRevo 1350 which has 150W less capacity.

Besides its monstrous capacity and the already mentioned Gold efficiency, the Enermax MaxRevo 1350 W (or EMR1350EWT) features eight PCIe connectors so it can support up to four high-end VGAs along with many other power hungry components. Since we can test up to 1800W at +12V alone (or 150A at nominal voltage) and 2250W in total we will easily push the Enermax MaxRevo 1350 W to its limits.

Specifications

The warranty is long enough, the price is at normal to good levels for a 1350W Gold PSU and the twister bearing fan promises increased longevity along with high cooling capacity and low noise output, at least at low-medium loads.


With 1350W capacity six +12V rails is a reasonable number. The OCP trigger range on them, according to Enermax, is between 40-50A. Also the huge 1620W peak power looks strange for an only (!) 1350W PSU. The 1500W MaxRevo has only 30W more peak power at 1650W, so it seems that the EMR1350EWT shares many components with its bigger brother which allows a huge overclock in power if needed. Finally from such a powerful PSU we expected more than 4A power at 5VSB.

Cables & Connectors, Power Distribution

As expected, a huge number of cables/connectors are provided. First of all the unit uses a fully modular cabling system, something very convenient especially for cable management. As you can see eight PCIe connectors are provided via four cables. Each PCIe cable at around 350mm splits into two smaller ones with one PCIe connector each. Also the available sockets on the modular PCB for the PCIe cables and the separate EPS/ATX12V connector are six in total. So you can buy up to two additional PCIe cables and have twelve PCIe connectors, if you don't use the second EPS. Also you have at your disposal 14 SATA connectors and ten peripheral ones. We don't think that there will be anyone asking for more.
The 24 pin ATX along with the EPS and the PCIe connectors use thicker 16 AWG wires while all others are equipped with 18 AWG, the recommended minimum wire size by ATX spec.

The PSU features six +12V rails and since the power distribution is rather complicated, the following illustration will help you understand what's going on.
