The power supply does not pull?

Question

Power Supply

My computer is in the photo.



And a power supply to it.



If you include another monitor in the computer, as well as a USB Wi-Fi adapter, then the computer is stupidly cut down.
The light on the power supply goes off.

After that, you can turn on the computer only if you pull out the cord that goes from the outlet to the power supply for a few seconds.

Maybe you need a more "different" PSU?
I ask for advice.

Answer 1

You marked your question as simple, but it's not that simple.

After that, you can turn on the computer only if you pull out the cord that goes from the outlet to the power supply for a few seconds.

This is a sign of a power overload if the protection is acting as a trigger (this is not always the case, but it is common).
However, there are some misunderstandings in your question.

If you include another monitor in the computer

The monitor is connected to the computer as a video signal receiver, such a connection does not create an additional load on the power source (the monitor has its own separate PSU). Therefore, it is not clear how connecting a monitor can cut down the PSU.

as well as a USB Wi-Fi adapter, then the computer is stupidly cut down.

But a USB connection, unlike a monitor, adds this load, albeit slightly (the standard for USB-2.0 is only 2.5 watts, quite a bit, and for USB-3.0 - 4 watts, also not cool). So with USB, an overload that cuts out an 80-watt power supply does not look too adequate either.
Checking overload via USB is elementary simple - you need to insert an intermediate link between the computer and the connected device - a USB hub with external power . If the matter of cutting down the PSU was precisely because of the overload on the USB power supply, then the hub with external power supply should stop this.
And as for the monitor... Little information, details are needed, and providing them is up to you.
