User’s Manual
Dear customer,
Thank you for choosing this ENERMAX power supply unit (PSU)! Please read this manual
carefully and follow its instructions before installing the PSU.
We would like to draw your attention that a computer required very specific conditions to work best
for you without failing. To avoid failures and to increase lifetime of the system, we suggest that:
Your system is NOT located near a radiator or any other heat producing device
Your system is NOT located near a magnetic device
Your system is NOT located in a moist and/or dusty and/or vibrating environment
Your system is NOT exposed to direct sunshine
Your system is sufficiently cooled by additional fans
If you use AC extension cables, please make sure it can support all connected appliances’
potential peak power draw. Or redistribute other high power consumption equipment, such as
laser printers or monitors to other AC wall outlets. Exceeding the extension cable’s loading
capacity could trigger its circuit breaker and cut off the power.
If you want to add the UPS (Uninterruptible Power Supply) for your system, please choose
adequate Watts/VA capacity UPS.
Ex.
PSU Model
Suggested minimum UPS output power capacity
(Based on efficiency & PFC at respective load)
EDF550AWN
600W / 1000VA
* Please do not mistake VA capacity as Watts, or use insufficient power UPS. This would result in
less
UPS battery runtime or the inability to power the system in battery mode.
* If you intend to add other appliance powered by the same UPS, such as monitor or printer, please use
higher capacity UPS according to all connected devices’ rated power draw.
* Enermax recommends “Pure Sine Wave” output in battery mode UPS with this PSU.
NAME OF PARTS
#1 To ensure best system cooling, do not block PSU air vent area.
#2 When assembling or maintaining the system, please remove AC cord from AC inlet, or turn ON/OFF
switch into “OFF” position. Then you can safely service the system.
#3 AC cord can get loose in many ways. The ENERMAX CordGuard lock can fix your AC cord tightly to the
PSU, so that it will not be easily detached and avoid shut-downs of your PC. The following is CordGuard
installation:
(unit: mm)
1 Honeycomb air vent # 1
2 ON/OFF switch (I=ON, O=OFF) # 2
3 AC Inlet # 2
4 CordGuard
