COMPATIBILITY
ENERMAX REVOLUTION D.F. 2 series is compatible with:
«Intel ATX Power Supply Design Guide v2.53 specification and downward compatible with v2.4
This PSU does not support motherboard with ISA expansion slot, which might require -5V power. —5V has been cancelled from Intel ATX v1.3 specification onwards.
To avoid failures and to increase lifetime of your entire PC, we suggest you to make sure that:

  • Your PC is NOT located near a radiator or any other heat producing device
  • Your PC is NOT located near a magnetic device
  • Your PC is NOT located in a moist and/or dusty and/or vibrating environment
  • Your PC is NOT exposed to direct sunshine
  • Your PC is sufficiently cooled by additional fans

We do not recommend using PC systems with fanless cooling, because a potentially high inner temperature decreases stability and lifetime of all components inside your PC!

BOOTING YOUR SYSTEM

Before booting your system, please check that:

  1. Allneeded connectors are properly connected.
  2. AC cord is properly connected to wall plug and PSU AC inlet.
  3. Turn on the power supply by switching the I/O switch to “I”, and your system is ready.

PROTECTION, SAFETY & SECURITY

This ENERMAX PSU features multiple protections. In case of most abnormal situations, the power supply will automatically turn off to avoid potential danger to itself and other PC components. If you have any question or need support, please contact your reseller or nearest ENERMAX subsidiary/agent or ENERMAX headquarter service center.
