GPGPU Support on the PCIe Risers
9.2.1
GPGPU Power
The power to the GPGPUs is supplied via the PCIe Riser Slot and the Power Distribution Board.
The 300w GPGPU power requirements are satisfied by:
75W from the PCIe connector
225W from the auxiliary connector on the Power Distribution Board (PDB)
The PDB auxiliary power connectors, J9 (Left) and J10 (Right), labeled for GFX add-in card,
provide auxiliary power to GPGPU devices.

GPGPU Cable
The GPGPU cable uses the mini-Fit Jr HCS contact that is rated for 9.5A for a four circuit
connector. Power delivery is 2 contacts * 9.5A * 12V = 240W. Since the cable needs to support
225W and the cable can support 228W, there is a 3W margin.
Note: The GPU power cable is not a productized component. Contact your Intel support
representative for information on how to obtain the GPGPU power cables.
