Speaker voltage/current questions

[ProfessorMoriarty]

My living room breaker is 20a, with a 12a air conditioner in line... my PC is running off an corsair rm850 and 2 monitors, would I be able to have a decent sized sub or PC speaker system in line as well? (Speculating 300 watt, 34.6V RMS)

A power supply does not always draw its maximum current so therefore the answer to this question would be dependent on the total power draw of the pc at its full utilization. I would enter your system specs into a computer power draw calculator or plug into a wattage tested and look at the wattage being used by the matching while doing an intensive task such as a stress test (causing the full computational usage of the computer). I would recommend using "Outervision Power Supply Calculator" in order to determine the wattage rating that your PSU is recommended to be rated to supply and compare that to the wattage rating of your current power supply in order to determine if you would be able to have the additional 300watts of load be able to be handled by your PSU.

Assuming you have 12Gauge wire, that you're operating at 230v, You're curently pulling around 18A when everything is at maximun load. with 300watts you stay barelly under the limit (at max load again). So it's going to work, But you may experience issue if you run everything at theire max rated power.

300w from the wall is only about 3a

Yes, you are far form overloading the circuit.

20Amp breaker, -12Amp A/C (pretending its drawing the fill ratting) = 8Amps

8ax110v= 880w

so you could run a 300w sound system no problem.
