Plugging power supply into extension cord

LilPach

So I’m getting a new desk, and plan to put my pc on top of it to show it off. Only problem is the psu power cord isn’t long enough to reach my surge protector. My question is can I plug the psu power cord into an extension cord (3-6ft) to reach my surge protector?

Yes. Unless you have a very high end PC with a very high wattage power supply you can use any normal grounded extension lead.

As said that's perfectly acceptable given your extension cord is not as thin as a shoe string, any normal general purpose (18AWG) extension would work.

Is 750w power supply with a 3070 and Ryzen 3700x considered high wattage? And when you say grounded lead you mean with 3 prongs, not 2?

You'll be fine with basically any grounded extension lead then. And yes, the 3rd pin is the ground pin.

*edit*

 

750watts / 120v = 6.25 amps

 

14 gauge is rated for 11-12 amps.  16 gauge is 7 amps (840 watts).  So 16 gauge will work. But--as I recommended--just get a 14 gauge extension cord, so you don't have to worry about it.

Keep in mind the lengths of run these are for.  for a short run of 6', 18 gauge should work--the issue is that if you need to go longer, are you going to remember to get a bigger gauge cord?
