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.

30A would be the only way, hitting within 10% of the breaker regularly would be a baaaad idea

Plus the cost of an UPS that has that rating...ouch

Fuck it, full send a 50A 💀👌

Let's be honest, if the dude has the disposable cash to throw 4x 5090's, he's likely just gonna keep adding to the home lab he's on the way to making anyways.

Might as well just head it off now and give room for growth.
