Before Power On-Power Supply and Stand By Voltage

PS-ON# is an active low signal that turns on all of the main power rails including 3.3V, 5V, -5V, 12V, and -12V power rails.

5VSB is a standby voltage that may be used to power circuits that require power input during the powered down state of the power rails.

When 5VSB and 3VSB send to SIO and SB
SIO will send this signal ‘’RSMRST# ’’ to SB’s boot up circuit to notice the MB is ready to boot up! If this signal is Lo, you can’t boot up MB.

Do you know when RSMRST# is Lo?
The answer is unplug the ATX connector!

1. Use multi-meter to measure 1k ohm near the battery circuit, the value between 1mV~10mV is ok, out Of this range is NG.

(According to Ohm theory: I=V/R, the Current leakage should be 1uA~10uA.)
