PCIe power cable

[johnm571]

Hi. Want to fit a NVIDIA Quadro RTX 4000 to a HP Z4 workstation. An error message appears which says "Please power down and connect the PCIe power cable for all graphics cards". No cables in the PC matches the socket on the graphics card. Any advice on the connector/cable required here please?

The graphics card requires an 8-pin power connector

Here is a post explaining the graphics power connections

Scroll down to the 8-pin connector section.

If that PC does not have that type connection on the power supply, then there are adapters available.  I see other graphics cards listed as the options that require the 8-pin power connection, however, unless your unit has the 450W power supply.  The other listed power supplies have at least the 6-pin power leads, in which a 2-6-pin to 8-pin adapter can be used.  Otherwise an adapter similar to this is needed.
