Have you check the power cable connection? Is there any LED indication of power when you press the power button? If your Optiplex 9020 us a SFF or MT then locate the power supply test button on the back side of the chassis. Press the button and check if the green LED glows. Was there any recent hardware change made to the system post which you faced this issue?
There is no information to go on so no you cannot be helped.
9020 has several sizes and and AIO model.
The Optiplex sell with six different chassis types. Knowing which one you have and posting it in your Forum thread title can assist our users in troubleshooting.
MT (Mini Tower) DT (Desktop) MFF (Micro Form Factor) SFF (Small Form Factor) USFF (Ultra Small Form Factor) AIO (All-in-One)
Thanks for the video but we do not have the same problem. I have already done this test but there is nothing. The power suply works well. I can not test to find the problem.

The BIST button on the back GREEN LED just indicates that there is AC power available.
It is NOT an indication that the power supply is Good.

I have already seen the green button and I have already tested. The power box works but there is nothing after.
No, I have not met yet.
WHAT CAN I DO NOW?
THANKS!

"The BIST button on the back GREEN LED just indicates that there is AC power available.

Good to know. I wonder why they bothered with the switch, as a simple ac indicator led would do the same job.
Then again dell does lots of strange things, and keeps them mostly secret

You have bad power supply.
There are no soft fixes for physically bad power supply.

The Built in Self Test Button is VERY Specific.

Hello Kewel,
Would it be possible for you to private message me the service tag of the system so that I can review and advise accordingly further?
