Will a power supply work without being
connected to the motherboard?
Question:
Will a power supply work without being connected to the
motherboard?
Answer:
Power supplies and the
fans
within them turn on/off from a signal they receive from the
motherboard. Therefore unless
your power supply is connected to a working motherboard that can
send a signal to turn on the power supply it will not work. This
also applies to power supplies that have an on an off switch on
them.
