3.2.1

Power Supply Module Card Edge Connector

Each power supply module has a single 2x25 card edge output connection that plugs directly into a matching
slot connector on the server board. The connector provides both power and communication signals to the
server board. The following table defines the connector pin-out.
The server board provides several connectors to provide power to various system options. The following sub-
sections will identify the location; provide the pin-out definition; and provide a brief usage description for each.
3.2.2

Riser Card Power Connectors

The server board includes two white 2x2-pin power connectors that provide supplemental power to high power
PCIe x16 add-in cards (GPU) that have power requirements that exceed the 75W maximum power supplied by
the PCIe x16 riser slot. A cable from this connector may be routed to a power connector on the given add-in
card. Maximum power draw for each connector is 225W, but is also limited by available power provided by the
power supply and the total power draw of the rest of the system. A power budget for the complete system
should be performed to determine how much supplemental power is available to support any high power add-
in cards.
Note: GPU add-in cards cannot be supported in a 1U server system.
