350W Power Subsystem
Revision 2.1
21
Intel order number G17455-005
Notes:
1. Maximum input current at low input voltage range should be measured at 90 VAC at max load.
2. Maximum input current at high input voltage range should be measured at 180 VAC at max load.
2. Maximum input current at high input voltage range should be measured at 180 VAC at max load.
4.7 Output Power/Currents
The following tables define two power and current ratings for this 350-W power supply. The
combined output power of all outputs should not exceed the rated output power. The power
supply must meet both static and dynamic voltage regulation requirements for the minimum
loading conditions.

4.8 Protection Circuits
Protection circuits inside the power supply should
cause only the power supply’s main outputs
to shut down. If the power supply latches off due to a protection circuit tripping, an AC cycle
OFF for 15sec min (with +5VSB/0.1A) and a PSON# cycle HIGH for 1sec shall be able to reset
the power supply.

the power supply.
4.8.1
Over Current Protection (OCP)
Each output shall have individual OCP protection circuits. The PSU shall shutdown and latch off
after an over current condition occurs. Whereas OCP of +5VSB shall turn the power supply into
“hiccup mode” until the OCP condition removed. The values are measured at the PSU harness
connectors and shall not be damaged from repeated power cycling in this condition. There shall
be current sensors and limit circuits to shut down the entire power supply if the limit is
exceeded. The limits are listed below.
