Enermax Modu87+ 700w PSU Review

Rating: 9.0.

Enermax Technology Corporation are one of the most highly regarded power supply providers to the enthusiast marketplace. I have owned many over the years myself, long before I worked for any publication. They have never let me down and they are one of the few companies I immediately shortlist if I am in the market myself for a new unit. The 1250W Revolution is still a mainstay in the KitGuru review test bed units.

We have the ModU87+ 700W unit in our labs today and we are excited to review it, because of the technology they have incorporated inside. The ModU87+ range is a reflection of their most efficient range of units on the market and is targeting a similar audience to the previous Infiniti range.

With the new PSU range Enermax have developed some key concepts. A Dynamic Hybrid Transformer Topology is in place to reduce energy loss on the first AC Stage. This is based on a resonant topology, the basic principle of which is already used in LCD panels. Until recently however the technology was static by design and unstable when translated into PC power supply designs. Enermax were able to eliminate the static nature however, due to a dynamic chain of capacitors and transformers. In reality this means that the Modu87+ (and Pro 87+) can reach a peak efficiency of up to 93 percent at 230V, giving a 80 PLUS Gold certification.

Additionally to aid with cooling they are using one of their new Twister Bearing fans which reduces noise levels. Their new controller system also means that the fan can spin at 330rpm under low load, which is inaudible, unless recorded by specialist equipment. Even when loaded the 13.9cm fan is not meant to exceed 1,000rpm, which in theory should mean a very quiet running unit.
