Help with short circuiting with extension cord.

Hi so im looking for a short term solution for home office short circuiting because of an extension cord.

Solution now is unplugging alls screens and more leaving just my pc plugged into the extension cord then plugging that into a wall socket in another room. Then replugging everything back into the extension cord, Kind of a hassle since office is well cable managed under tables and hard to reach.

(Long explanation) Office room has ungrounded wall sockets for the time being. Dont want to plug into that with 10.000usd worth of electrical. So i extension cord it into another room but ofc then with so many screens, printer, pc, racing simulator and more it just short circuits. I plug the cord into my kitchen where i have a 16Abraker socket and i dont have a higher one dont know if that helps.
