Question What cables do I need for this ancient computer?

[kook]

So I have this old computer from like 1990 and I want to power it on but I don't have any power cables for it.

On the back of the big monitor there is this socket:

Surprisingly it looks just like the socket I have on my modern computer.
Does that mean any normal power cable like this will work?

Above that socket is says

100 - 125 V / 200 - 240 V~; 50 - 60 Hz; 1.8A / 1 A;

though. Do I need a specific one?

And now as for the tower of the computer, this is the back of it:

Transcription for the label on the left:

100-125V~  2A MAX    200-240V~  1A MAX

. Not sure what that means.
The socket on the right looks like it's the same as on the monitor, but I'm not sure what the socket on the left is supposed to be for.
What cables do I need?
Then there's also this red switch in the middle that has three trigger levels (currently it's 230). Not sure what that thing is for either. Does anyone know what it's called?

I would greatly appreciate any help.

Yes.

Ignore that socket. Not necessary to use it.
It is used to connect monitor power directly to pc with this type of cable.

Then there's also this red switch in the middle that has three trigger levels (currently it's 230). Not sure what that thing is for either. Does anyone know what it's called?

That switch is for switching between different power grid voltages.
If your power grid is 220-240V (Europe), then leave the switch on 230V.
If your power grid is 125V (USA), then flip the switch to 125V mode.

Note - if you flip the switch to 125V and connect to 220V grid, then PSU blows up. Don't do that.

Powering up a computer with a 30+ year old power supply may be risky. If it pops and smokes I would not be surprised at all. If you have a fire extinguisher I would keep it close by.

You can go to any electronics store or amazon and buy the cable. Just look up IEC power cable. The three prong IEC has been the standard switching power supply input cable for as long as I can remember and I have been doing this since the late 80s.

Do not touch the red switch in the middle that has three trigger levels. Let it stay on 230, Otherwise the PSU will blow up
