2.2.2. Power

Given a specific airflow, the Intel® FPGA PAC D5005 can dissipate up to 189 W of power, of which up to 137 W can come from the FPGA. If the airflow is increased, the Intel® FPGA PAC D5005 may be able to dissipate up to 215 W; however, you shall bear the responsibility of thermal validation of these conditions.

The Thermal Design Power (TDP) (215 W) is based on the maximum current, per the PCIe* specification of 5.4 A from the 12 V- PCIe* slot and 12.5 A from the 12 V-Auxiliary 2x4 PCIe* power connector and requires optimized cooling conditions. The card TDP is limited to 189 W under the Thermal and Airflow requirement conditions.

As a developer or solution provider, you must design the AFU to stay within these power guidelines. If the AFU exceeds this limit or the limit provided by the qualified server vendor, Board Management Controller (BMC) safeguards will shut down the Intel® FPGA PAC. Typical server BMC safeguards will likely shut down the server as well. Functionality and reliability of the server and the Intel® FPGA PAC are not supported for AFUs that exceed the specification.

The Intel® FPGA PAC source power must be provided from both the 12 V- PCIe* slot and the 12V-Auxiliary 2x4 power connector.

The Intel® FPGA PAC D5005 is designed to operate under the following conditions:
Table 2.  
Operating Condition Description
No 12 V PCIe slot power, No 12 V Auxiliary Connector Power

Intel® FPGA PAC D5005 OFF

Only 12 V PCIe slot power, No 12 V Auxiliary Connector Power

Intel® FPGA PAC D5005 OFF

No 12 V PCIe Slot Power, only 12 V Auxiliary Connector power available

Intel® FPGA PAC D5005 ON, but limited by the total available power from 12V Aux power connector

12 V PCIe slot power and 12 V Auxiliary Power Connector available

Intel® FPGA PAC D5005 ON, normal operation up to maximum power capabilities of the PAC card design

The 12 V-Auxiliary power connector pin assignment defined by the PCIe* specification is shown below:
