Product Introduction

The Revolution SFX power supply series brings Enermax technology to a small form factor. The PSU uses high quality components like Japanese 105°C capacitors and DC-to-DC technology to achieve the 80 PLUS® Gold efficiency. Unlike most other SFX PSU's the Revolution SFX is available with up to 650W. With this wattage it can power even the latest high-end graphics cards making it the best choice for compact gaming systems.


  • 80 PLUS® Gold
    Up to 92 percent efficiency at 230V and 20 to 100 percent load. 80 PLUS® Gold certified.
  • Support of EU Eco-Design Regulations
    The Revolution SFX Series helps systems to meet the EU eco-design directive ErP Lot 6 2013 (< 0.5W in standby mode*) due to a high-efficient 5V standby (+5Vsb) circuitry as well as 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 Lot 6 2013 ready mainboard


  • DC-to-DC Design
    The secondary voltages (+5V and +3.3V) are generated by the primary voltage rail (+12V). Positive effect: Higher efficiency, clean output voltages (low ripple & noise) and a perfect voltage regulation at all loads.
  • Full GPU & CPU Power
    Massive 12V rail to power high-performance processors and graphics cards.


  • Compact Cooling Design
    The integrated 8cm fan with long lasting bearing technology ensures efficient and continuously silent cooling within limited space.
  • Smart Semi-fanless Design
    The semi-fanless design enables a completely silent operation below 30% load. Exceeding this limit stats the automated fan control regulating the RPM to to provide the opimal cooling with low noise level.


  • Full-modular Cable Management with flat cables
    Completely removable cables for easy installation and cable management.
  • Multi-GPU Support
    Two 6+2P (8P) PCI-E connectors to power the latest high-end graphics cards and multi-GPU systems.


  • Intel® Skylake™ Ready!
    Full support of the C6/C7 energy-saving functions of Intel® processors, first introduced with the Haswell™ generation.
  • Intel ATX 12V v2.4 and SFX 12V v3.3
    Compliant with the Intel Power Supply Design Guide for Desktop Platform Form Factors Revision 1.31 April 2013.

SFX Form Factor


The SFX formfactor was develpoed to provide a standard PSU size for small systems. The Revolution SFX keeps this standard with the size of 100mm width, 125mm depth and 63.5mm height. Included in the delivery Enermax provides an ATX adaptor for installing the PSU in larger cases.

Semi-fanless Design


The semi-fanless design allows a completely silent 0 dB(A) operation up to 30% load providing optimal conditions for silent and multi media systems. Above 30% load the automated fan control starts, keeping the PSU cool and quiet. Enermax uses a 80mm fan with lasting bearing technology for the Revolution SFX series to ensure the best cooling within limited space.

Full-modular Cable Mangement


The Revolution SFX is equipted with a fully modular cable management ensures easy mounting within small m-ATX cases. The black flat cables not only save space but also improve the air flow with less surface.
