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)
ERV550AWT-G	600W / 1000VA
ERV650AWT-G	700W / 1100VA
ERV750AWT-G	900W / 1400VA
ERV850EWT-G	1000W / 1400VA
ERV1000EWT-G	1100W / 1600VA

• 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.
• 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.

① Output cable: Please check "Cables & Connectors" section.
② Fan. #1
③ Honeycomb air vent.
④ ON/OFF switch (I=ON, O=OFF). #2
⑤ AC Inlet. #2
(6) CordGuard. #3

1 To ensure best system cooling, do not block PSU fan's air in-take and air vent area.

This PSU offers a special HeatGuard function. When the system is turned off, or goes into ACPI S3/S4 sleep mode, the PSU fan will keep dissipating the remaining heat for 30 60 seconds and prolonging system lifetime.

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:

① Set your PSU into the chassis, and please make sure the I/O switch is on “O” position.

② Press two sides of the CordGuard lock together, and set it into

CordGuard holder near the AC inlet.

③ Plug the AC cord into your PSU.

④ Lock CordGuard to latch onto AC cord.

1. CordGuard is for AC cords supplied with ENERMAX CordGuard-compatible PSUs. Other AC cords may be incompatible.
2. When assembling or maintaining the system, please remove AC cord from AC inlet, or turn I/O switch into "O" position.

CABLES & CONNECTORS

All connectors are designed to prevent insertion in wrong orientation. If you cannot easily insert a connector, please check if you are inserting the connector in the right orientation. Do not try by force to insert it nor modify the connectors. This might damage power supply and system components, and warranty shall be void.

Following graphic illustrates the modular sockets layout and its DC rail distribution.

(ERV750AWT-G / ERV850EWT-G / ERV1000EWT-G)

• This product incorporates multiple 12V rails over current protection.
