[1.3.15] Slot Power for High
Power PCIe Cards
[1.3.16] Standard PCIe Slots can provide up to 25W of power.
In order to support the additional power required by GPGPU
and high end graphic cards, 75W needs to come from each
designated high powered PCIe slot (regardless of 150W/225W/
300W Cards) in addition to supplemental power directly from
the Power Supply. For this reason, an additional 12V 2x2
power "plus" connector (12A per pin) will be required on the
baseboard (sourced from the PSU/PDB) to provide the needed
power to designated high powered PCIe slots. Below is a list of
possible power configurations supporting different high power
PCIe cards.
X16 150W card

75W from PCIe slot + 75W from PSU direct cable

attach: 75W (2x3 connector)
X16 225W card

75W from PCIe slot + 150W from PSU direct cable

attach: 75W (2x3 conn) + 75W (2x3 conn)
[1.3.17] OR
75W from PCIe slot + 150W from PSU direct cable

attach: 75W (2x3 conn) + 75W (2x4 conn)
[1.3.18] OR
75W from PCIe slot + 150W from PSU direct cable

attach: 150W (2x4 conn)
X16 300W card

75W from PCIe slot + 225W from PSU direct cable

attach: 75W (2x3 conn) + 150W (2x4 conn)
[1.3.19] OR
75W from PCIe slot + 225W from PSU direct cable

attach: 75W (2x3 conn) + 75W (2x3 conn) + 75W (2x3
conn) - Not preferred

[1.3.20] Nvidia SLI Support

[1.3.21] Due to licensing issues, S210-MBT2W Extreme Server
SKU is not allowed to support NVidia SLI configurations.
Although this has no affect on the hardware design, it would
have required additional BIOS support.
[1.3.22] ATI CROSSFIREX/PRO Sup-
port
[1.3.23] S210-MBT2W Extreme Server SKU must support up to
4-way multi-GPU configs connected through CrossFireX/Pro
flex cables. Maximum performance would have both GPGPUs
from a single processor. However, S210-MBT2W supports the
double-wide GPGUs from x16 slots on different processors. No
additional BIOS support is required to support CrossFireX/Pro
configurations.
