Can a PSU be "shared" between two systems

See pic for a schematic, is there any reason I shouldent use the same power supply to power a motherboard when that power supply is powering GPUs that are attached to another motherboard via pcie risers. The other motherboard in question is on a separate ps

You can use it unless your PS isn't capable of handling those extra GPU's

Simple answer is yes.
You do run the risk however of burning out the wires.

theoretical psu can be shared, but if one system start other also must start, and if one system crash second also be crashed.
I dont recommend use this scheme.
Better using 2 low end psu for rig mobos and one high end for gpu's, and connect all 3 psu black (GND) + Green (PS-ON) wire mixed
