Like Greengolfer I am not from Laminar Research; just a flight simmer living down under.
What is the capacity of the power supply for the PC. You need to check the requirements for the graphics card and then add some.
My research tells me the GTX 1060 has a 120W power demand with a recommended power supply of at least 400W.
On the basis you will add other bits and pieces you should consider an absolute minimum of 500w supply. An ideal situation would be 700w giving you plenty of grunt for added extras.
The business found at https://xforcepc.com/english/flight-simulation/flight-simulation-computers/platinum-html.html builds PCs predominantly for X-Plane and recommends a 700w supply for their GTX 1060 GPU. As a side issue XForce PC is the recommended PC supplier for X-Plane PCs within the USA
