Currently, 2 servers and 2 3d printers, I’m running just over 200w at idle. Depending on what my printers and servers are doing at any given moment, it could go up to 2000w, total, but I haven’t seen that high a power draw since I stopped contributing to Boinc projects about a year ago. I remember finding it mildly amusing that my graphics cards had a higher power draw then my printers.
