To compliance with on going energy saving regulations, such as USA low power requirement,
the PSU will turn off the PFC function in standby mode to increase the standby efficiency up
to 50~70% (whereas other power supplies only have 10~40% standby efficiency). This
design will emit a short “Tsst” sound when you power up the system. It is a normal
phenomenon and has no negative effect to whole system.
If your MB has ISA bus, this PSU might not be able to fully support it, because this PSU has
no
-
5V rail to support some ISA devices. This rail has been abolished from Intel ATX12V
v1.3 onwards. If you are unsure about MB’s and ISA card compliance, please contact the
respective manufacturer
PowerGuard Function
The Infiniti PSU is equipped with ENERMAX new PowerGuard function. The PowerGuard is
equipped with LED light and internal buzzer to indicate the power supply status. Under abnormal
status, PowerGuard will turn off the power supply to protect your system. PowerGuard LED
indications are as following table.

* When PowerGuard starts to beep under abnormal situation, you can press the red Reset button near the
LED light to temporarily deactivate the internal buzzer. When this happens, we suggest you turn off the
system and perform the system check. If after the system check, the PowerGuard still send out the alert or
the fault condition cannot be removed, please contact your ENERMAX agent, distributor or ENERMAX
headquarter service center.
** The power supply follows mainly ATX12V Power Supply Design Guide and has the minimum load
requirement. If you try to test the system with minimum system component (ex. only one hard disk and
onboard graphic), and the whole system consumes less than 20 watts, the PowerGuard will activate the alert
and could possibly turn off the power supply. You can add more peripheral, such as graphics card, hard disk
drives, and optical drives to avoid above situation resulting from minimum load requirement.
