ADM-PCIE-9V8 User Manual

2.2 Chassis Requirements

2.2.1 PCI Express

The ADM-PCIE-9V8 is capable of PCIe Gen 3 with 8 lanes, using the AMD Integrated Block for PCI Express.

2.2.2 Mechanical Requirements

An 8 or 16 lane physical PCIe slot is required for mechanical compatibility.

2.2.3 Power Requirements

The ADM-PCIE-9V8 draws power from the PCIe Edge and the 6-pin ATX power connector. The ADM-PCIE-9V8
does not use or require the 3.3V power from the PCIe Edge (though it does use 3.3V AUX). It can operate with
only the PCIe edge if desired. To operate with PCIe edge only, ensure SW1-3 is OFF (see Switches). As per
PCIe specification, users should limit the board power consumption to 66W when using only the PCIe edge
power. Adding the 6-pin ATX connector provides additional 75W of power, bringing the total board power
dissipation maximum to 141W.
Power consumption estimation requires the use of the AMD XPE spreadsheet and a power estimator tool
available from Alpha Data. Please contact support@alpha-data.com to obtain this tool.
