Power Supply Connector(ATX, AUX)
The GeniuX 1 green mainboard supports the standard industrial ATX power supply . Check
the ratings of the power supply installed to ensure it meets the following requirements.
Power requirement
Normally the maximum rating power for the power supply installed should be at least 300W.
If there are too many peripheral devices in your system, a stronger power supply is
needed.

The 5VSB line current of the power supply should be taken into consideration. If it is less
than 0.72A, the system may not work properly. If a PCI card using 5VSB line is inserted, the
5VSB line current of the power supply should be more.
The mainboard provides two power connectors (ATX, AUX), as noted below:
Assistant Power connector(AUX) is an optional connector. If there are too many
peripheral devices in your system, a power supply with this assisatnat power
connector is recommended to be used.
Power Switch (POWER)
The power switch (POWER) should be connected to a momentary switch. When powering
up your system, first turn on the mechanical switch of the power supply (if one is pro-
vided), then push once the button of the power switch. W hen powering off the system,
you needn' t turn off the mechanical switch, just push once the button of the power switch.
If you change "soft-off by PW R-BTTN" from default "Instant-off" to "Delay 4 Secs" in
BIOS Setup (POWER MANAGEMENT SETUP), the power button should be pressed for
more than 4 seconds before the system powers down.
