Interpreting PSU test results
Interpreting PSU test results
I assembled a new setup using the Cooler Master NR200P Masterbox cabinet, and the PSU came pre-installed. After completing the build, nothing activated—no fans or lights. Once, I noticed the power switch light turned on briefly, but only once. Given the possibility of operator error, I didn’t assume the PSU was faulty, so I used a Kingwin power supply tester for further testing.
Which model Kingwin?
PG = Power Good Signal.
This might not always be accurate.
It’s advisable to try or test the Kingwin on a known functional PSU to verify if the tester is working properly.

Refer to the motherboard’s manual to confirm all connections are correct.
Check each installed part as well.
In a new build, some connections might not be fully secured.
Avoid forcing connections, as what appears connected may not be.
Carefully (with power off and cable removed) remove and reinsert all connections.
Look for any signs of damage, debris, or loose parts.
It’s possible that something shifts slightly and then everything functions correctly.
Cooler Master indicated the PSU wasn't optimal according to the reading I provided. They advised returning it for repair. After several attempts with different setups on the MOBO, everything functioned properly. I'm not sure if the reading affected the outcome. It seems the main issue was connecting things correctly.
