ENERMAX is stepping up to the need of energy and money-saving products with these two desktop PSU series with models in 500, 600, 700 and 800W. PRO87+ is the native cable series, while MODU87+ is modular. Both will complement ENERMAX’ running 80+, 82+ & 85+ PSU series and incorporate the latest technologies with a major breakthrough:

DHT, Dynamic Hybrid Transformer Topology
To improving the efficiency all manufacturers concentrated on the DC stage, up to now. But the technology used in the DC stage (during and after conversion of AC to DC) has come to the maximum and achieving 87+ efficiency is the very limit of this approach. To achieving 87+ or even higher efficiency with good performance needs additional innovations on the AC stage. ENERMAX has invented three innovations bundled into the new DHT-topology:

Obviously, the inventions center around the adoption of dynamic frequencies, voltages and conversion instead of traditional static ones. These dynamic optimization designs not only push the efficiency up to shocking 92%, but also improve stability and performance to new heights without sacrificing any safety or regulations. Moreover, the incorporation of a 13.9cm Twister bearing fan with the patented SpeedGuard fan control bring PRO87+ and MODU87+ to unprecedented silence @ 50oC.

When you power the unit on, you will be pleasantly surprised with how quiet it operates, even at full load (simulated) and delivers a clean pulse of power throughout our testing period.


There is no doubt that it is a solid hitter for any enthusiast looking for a rock solid power supply. The numbers speak for themselves and there is quality built into every inch of this PSU. I would happily recommend this unit for anyone looking for a high performance power supply.

PureOverclock Editor Choice

From a functional standpoint, the Enermax Modu 87+ has an 80+ gold certification rating. The 140mm fan in this PSU was inaudible when at low or high rpm with the graphics card and CPU cooler directly beside it. The Modu 87+ seemed to stay quite cool to the touch even when being tested.

PC Perspective Silver Award

So yes, need I say more? Enermax did it again. An extra pinch of innovation brought their already excellent PSU line a little further into the stratosphere. We are handing out our best hardware award, very seldom granted to any product. Heck, it's well deserved, what a great PSU.


For their outstanding performance, high efficiency, the for all intents and purposes silent operation, we are awarding both the Enermax Pro87+ and Modu87+ series our Gold Editors' Choice award. The price may be high, but these are currently the best power supplies in the market.


Our third 80 Plus Gold unit to be tested here at the site has come and shown us what it's made of, and has turned out to be quite a decent power supply. The Modu87+ 700 watter is incredibly efficient, it keeps its voltages relatively stable, and it has good ripple and noise suppression.


Enermax MODU87+ 700 W is a terrific power supply, achieving very high efficiency between 86% and 90.5%. Voltages were always inside the required range with low noise and ripple. The protections are active and tightly configured. And the cable configuration is perfect for a 700 W product. For the user looking for “the best” 700 W unit around and price isn’t a concern, the new Enermax MODU87+ 700 W is certainly the best pick.


Unboxing and First Look


This power looks greats, has a quiet 135mm fan, modular highly efficient, is compact, comes with a 5 year warranty and much more. This is exactly what you should be looking for in a power supply.
