We recently settled into a new home and have faced problems with circuit breakers blowing. In our previous residence, such issues never occurred—I could power my computer and two 3D printers simultaneously. The transition also included an upgrade to a 3070ti processor and an 850W Gold power supply. I’m unsure if the breaker problems are related to the house itself or if the power supply can trigger them.

Curious point, but do you remember how the wiring connected your old home to your new one? Some systems might have shared circuits for different areas, or each room could be powered by its own circuit. I’m sure it’s more complex than just one circuit per room. Your example with the living room and master bedroom/bathroom makes sense from what you described.

Determine the total load on the breaker panel. Comparing different situations is like saying apples to oranges. Wiring standards and electrical codes vary over time, so what works today might not fit tomorrow. If your panel only has a 15-amp rating and it can't handle more, you'll need to upgrade the wiring or split the circuit into separate sections. Sometimes older homes are repurposed with DIY fixes, but they often end up with circuits that aren’t strong enough for modern use. Switching to LED lighting helps lower overall demand and gives more flexibility. Ideally, every home in the U.S. should have at least a 25-amp breaker, though finding such a setup is rare.

P.S. Based on the relationship Amps*Volts = Watts, a 15-amp breaker on 110V power can handle up to 1650 watts. Assuming your PSU is only about 80% efficient, it will draw roughly 1050 watts from the circuit. That means you’re looking at around 600 watts of usable power at full capacity—especially if you’re running multiple devices like a monitor, speakers, 3D printers, and more.

They recommend estimating based on 80% of the breaker's capacity. This means you're using 12 amps rather than the full rating. The calculation should reflect 1320 watts or 1440 if you're working with 120 volts instead of 110 volts.
