Issue Details

  • I'm performing a power budget for a system, and need to know how much total power my system will use.  What are the power draw values for an empty PXI, PXI Express, or SCXI chassis?
  • What is the idling power consumption of the PXIe chassis?
  • What is my PXI or PXIe empty chassis power consumption when the fans are set to high or auto?


National Instruments estimates empty chassis power draw for the following chassis:
