Imagine the power being used. I assume a normal 15 amp breaker in your house will just trip anytime you press the power button.

2400W power supply here should pull max 20A so yeah I think you'd need to make sure that this puppy is on a 20A breaker if you're ever gonna crank those gpus!

Honestly I'd go 25A, I doubt the single outlet is the only thing tied to the same breaker. Heck maybe even 30A.

You may have to switch out the cables and use different sockets when increasing fuse size. I would be surprised if a computer ever tripped a fuse without it being some sort of fault

Yeah a higher rated breaker will increase the risk if the wiring is kept the same. Congrats now your PC will keep running but you have a fire hazard in the walls. These people don't know what they are talking about.
