you will only need surge protector if your power is very unstable, most likely running a pc from power generator, honestly, dont waste your money.

pc alone, plus good gpu, usually load is ~160-200 watt, thats less than 1 amp off 240v

3 core is needed yes, but i dont think there is special requirement on how fat the cable is, get common 1 will do, those cheap power extension that labelled 2500w will do. pc nowsaday drain very little power, if your pc is like 10k+ then assume 300watt

1.25 mm² copper is enough for 13 amp, usually those wire in the wall should be fatter than your extension wire, so if you overload you want those wire in the extension to burn first, not those in the wall. but still the fuse should work 1st b4 any wire burn, but you dont need wire thicker than those wire in the wall. just incase anything goes wrong, you just need to replace the extension, not open up the wall.
