This may seem like a silly question. I have a 1500 watt power supply (corsair). Does the psu take a continuous 1500 watts, or does it only draw in the power your computer is actually using? My house circuit is 15 amps ~ 1800 watts. Keep in mind that two rooms are connected to the same circuit. The other room has a PS4 on almost 24/7 and lots of electricity is drawn from the second room. Will the circuit breakers keep shutting off the electricity, or am I fine?
