Before installing the USB-6453 or USB-6453 (OEM), confirm how much power the USB port to which you plan to connect provides.

The USB-6453 or USB-6453 (OEM) can consume up to 6.1 W of power when fully loaded at maximum rate. Therefore, NI recommends using a USB port that can provide at least 7.5 W of power.

The following table lists the power provided by the different types of USB ports and the level of functionality each type supports.

Table 42. USB-6453/USB-6453 (OEM) USB Port Power Compatibility
USB Port Type Typical Power Provided Supported Functionality
Type A, USB 2.0 2.5 W Not supported
Type A, USB 3.0+ 4.5 W Supported with limited functionality
Type C, USB 2.0 2.5 W Not supported
Type C, USB 3.0+, default 4.5 W power only 4.5 W Supported with limited functionality
Type C, USB 3.0+, supporting 7.5 W or more 7.5 W Supported with full functionality
Check the documentation for your computer or hub to determine if a USB Type-C port provides at least 7.5 W or more of power.
Generally, any port advertised with any of the following features should be able to provide 7.5 W of power.
  • Thunderbolt support
  • USB4 support
  • Dual lane support (for example, USB 3.2 Gen1x2, where "x2" indicates dual lane support)
  • USB Power Delivery support

If you are using the USB-6453 or USB-6453 (OEM) on a port that only provides 4.5 W of power, you can configure the USB-6453 or USB-6453 (OEM) to consume less power. The following table provides a few example configurations that limit power consumption to be less than the minimum power provided.
