OVERVIEW This application note discusses the power requirements of the NVIDIA® Quadro® line of desktop graphics cards. A suitable power supply is necessary to maintain system integrity under computational load. Figure 1. NVIDIA Quadro Graphics Cards POWER REQUIREMENTS The Quadro desktop graphics cards may require auxiliary power within the host chassis. Ensure that your system can deliver the necessary wattage and auxiliary power connectors for all cards in the system.
Overview Table 1.
Overview Cards with a TGP of up to 250 W will utilize two 6-pin PCIe auxiliary connectors or a single 8-pin PCIe auxiliary connector. Figure 2. PCIe Connectors POWER REQUIREMENTS FOR 250 W CARDS WITH A SINGLE 8-PIN CONNECTOR Typically, the PCIe slot is rated for 75 W and the 8-pin PCIe connector is rated for 150 W. However, based on our testing and surveying the current ecosystem, it was found that the 8-pin PCIe connector can drive up to 175 W.
Overview POWER ADAPTERS It is extremely important to understand the board power requirements when selecting power supplies. It is recommended to use a power supply that has all the required connectors. However, if the required connector is not available on a given power supply, it is possible to use adapters to convert existing connectors to PCIe auxiliary connectors. When using power adapters, it is important to evaluate the rated amperage on the 12V rail that is being used to source the adapter cable.
Overview the 12V rail on the power supply driving this is capable of handling the additional connector. Refer to the rated amperage on the 12V rail sourcing the splitter to ensure that the connector limits are not exceeded. Figure 4. 8-Pin to 6-Pin Adapter Cable PCIe Dual 6-Pin to 8-Pin Adapter Cable It is possible to combine two 6-pin auxiliary PCIe connectors into a single 8-pin auxiliary PCIe connector.
