Is it possible to run a PC with ATX power connectors without issues?
There is repetition in the connector description because several wires carry 3.3v, so losing one won't likely halt the system, though it might lead to instability.
Your setup would probably activate without the +4 pin being connected at all.
Still, leaving a loose wire exposed poses risks—it could short-circuit, potentially shutting down the device or harming components.
I’d replace the power supply or cover the exposed wire with electrical tape or heat shrink.
