How to test power supply

"1.Plug in two prong power cord into PSU

2. Flip over power supply

3. Insert positive and negative prongs from multimeter into two holes

on the bottom. Be sure they are fully inserted and not touching any

metal or each other.

4. Set multimeter for DC voltage at ~20v.

7. Use a small piece of metal and make contact with the

first (5VSB) and 3rd(ACDC_STBY) pin

of the connection on the side.

Make sure whatever you are using to jumper the pins makes

contact with the metal connectors in the connector.

This turns on the power supply.

8. If you have done it correctly and the power supply is good,

you should get a reading of around 12 volts as shown."

"Hi, i need your help regarding my adp-200er from 12xx serie. i'm trying to check if the psu is my problem on my ""no power"" ps4

so here is my situation. i put black and red sticks inside the PSU, then i try to jump the 4 pins to watch my readings

when i jump the first and second pins i have no readings

when i jump the first and third pins i have the 12vdc reading

when i jump the first and fourth pins i have no readings

when i jump the second and third pins i have no readings

when i jump the second and fourth i have no readings

when i jump the third and fourth i have the 12vdc reading

do you think the PSU is half working? do i have to replace it?

thanks anyway for any advice"

you might check your APU chip, if that comes off, or if any of the suturing points come unsutured, then you need to get a new ps4
