What is power good signal voltage?
The power good signal is a +5 volts signal that is generated by a switching power supply when the supply has stabilized its output voltages and passed all its internal self-tests.
What does the Power Good signal do?
The Power Good signal (power-good) is a signal provided by a computer power supply to indicate to the motherboard that all of the voltages are within specification and that the system may proceed to boot and operate.
What are the symptoms of power problem?
Common power-related symptoms include:
- Any power-on or system startup failures or lockups.
- Spontaneous rebooting or intermittent lockups during normal operation.
- Intermittent parity check or other memory-type errors.
- HDD and fan simultaneously failing to spin (no +12V)
- Overheating due to fan failure.
What color are 12V power supply connectors?
The red terminals are for the positive 3.3V, 5V and 12V connections; the black terminals are for ground.

Why does a power supply have different colored wires?
Have you ever wondered why the plug from the power supply to the motherboard has so many different colored pins and wires? It’s to provide different voltages of power signals to the motherboard, which then parses them out to connected devices.
What is the difference between a switching power supply and a linear power supply?
Switching power supplies feature higher efficiencies, lighter weight, longer hold up times, and the ability to handle wider input voltage ranges. Linear power supplies are usually less expensive, but are limited in capability and tend to be larger in physical size.
Can I use a switching power supply to drive a DC motor?
A simple unregulated analog power supply may be easier and be able to supply the large starting under load current more that the switching one. DC motors are not too fussy about the supply, and will usually run quite well on unfiltered DC.
