2.3 460W Power Supply
This specification defines a 460W redundant power supply that supports server systems. The
parameters of this power supply are defined in this specification. This specification defines a
power supply with 2 outputs; 12V and 12V standby. The AC input shall be auto ranging and
power factor corrected.
2.3.1 Mechanical Overview
The physical size of the power supply enclosure is 39/40mm x 73.5mm x 185mm. The power
supply contains a single 40mm fan. The power supply has a card edge output that interfaces
with a 2x25 card edge connector in the system. The AC plugs directly into the external face of
the power supply. Refer to the following figure. All dimensions are nominal.

2.3.1.1 DC Output Connector
The power supply shall use a card edge output connection for power and signal that is
compatible with a 2x25 Power Card Edge connector (equivalent to 2x25 pin configuration of the
FCI power card connector 10035388-102LF).
