Up to 92% efficiency at 230VAC between 20 and 100% load. The REVOLUTION87+ series is 80PLUS® Gold certified.

REVOLUTION87+ helps systems to meet the EU eco-design directive 2013 ErP Lot 6 and 2014 ErP Lot 3 (< 0.5W in standby mode*) due to a high-efficient 5V standby (+5Vsb) circuitry. Moreover it supports the EU regulation no. 617/2013 demanding amongst others 85% efficiency at 50% load and 82% at 20% and 100% load.

* only in combination with an ErP ready mainboard


The DC-to-DC design generates the secondary voltages (+5V and +3.3V) from the primary voltage rail (+12V). The positive effect is higher efficiency, clean output voltages (low ripple noise) and a perfect voltage regulation at all loads.

The dynamic hybrid transformer topology allows an optimized use of the transformer with less energy loss for a better overall efficiency.

A multi-rail design with four 12V rails distributes the power with maximum stability and safety.


Modular & Flat Cables simplify the cable routing and improve the airflow inside the case.

Six 6+2P (8P) PCI-E connectors to power multiple high-end graphics cards.


The integrated 13.9cm Enermax fan with patented Twister Bearing™ technology ensures an efficient and continuously silent cooling and long lifetime with up to 160,000 hours MTBF.

Silent and powerful cooling performance due to the advanced and intelligent SpeedGurad fan control.

The HeatGuard function keeps the PSU fan running for 30-60 seconds after shut down to dissipate the remaining system heat and prolonging the components lifetime.


Intel® ATX12V v2.4, compliant with the Intel Power Supply Design Guide for Desktop Platform Form Factors Revision 1.31 April 2013.

Full support of the C6/C7 energy-saving functions of Intel® processors, first introduced with the Haswell™ generation.

Fit4Server: Compliant with SSI PSDG for the new Intel® Core™ Extreme/i7, Xeon™ and AMD® Opteron™ and downward compatible with EPS12V v2.92, v2.8.

Worldwide compatibility with automatic 100-240VAC input and up to 0.99 with active Power Factor Correction (PFC).

Quality & Safety

5 Years Manufacturer Warranty.

Enermax uses high-quality components including first-class Japanese 105°C electrolytic capacitors for maximum stability and durability.

Enermax SafeGuard, the multiple protection circuit that keeps the power supply and the system safe from damage by short circuit (SCP), over voltage (OVP), under voltage (UVP), over current (OCP), over temperature (OTP), over power (OPP) as well as surges and inrush current (SIP).

Non-Stop 24/7 industrial class performance. Full rated power output at 50°C ambient temperature.
