5.1.5.3 Voltage
Regulation
The output voltages must stay within the following voltage limits when operating at steady state
and dynamic loading conditions. These limits include the peak-peak ripple/noise. All outputs are
measured with reference to the return remote sense signal (Returns). The +12V3, +12V4, –12V
and 5VSB outputs are measured at the power supply connectors referenced to Returns. The
+3.3V, +5V, +12V1, and +12V2 are measured at the remote sense signal located at the signal
connector.

5.1.5.4 Standby
Operation
The 5V standby output is present when an AC input greater than the power supply turn on
voltage is applied.

The power supply fan is off (fan-less operation) when the power supply is in the stand-by mode
of operation. The power supply will work indefinitely in stand-by mode with the input AC power
on, power supply off, and the 5V stand-by output at full load (= 3A).

5.1.6
670W Protection Circuits
Protection circuits inside the power supply shall cause only the power supply’s main outputs to
shutdown. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF
for 15 seconds and a PSON# cycle HIGH for one second shall be able to reset the power
supply.

supply.
5.1.6.1
Over Voltage Protection
The power supply shall shutdown and latch off after an over voltage condition occurs. The
voltage shall never exceed the maximum levels when measured at the power pins of the power
supply connector during any single point of fail. The voltage shall never trip any lower than the
minimum levels when measured at the power pins of the power supply connector. 5Vsb (stand-
by) will be auto-recovered after removing the Over Voltage Protection limit.
