answer:Assuming your computer uses 250 watts which is probably a high estimate, and your monitors use about 100 watts which is probably high for even an old crt, you are using ~450 watts. This means you are probably pulling about 3.75 amps so as long as your circuit breaker is larger than 3.75 amps which I can tell you already it is, then you’ll be okay. Most likely you have at least a 10 amp breaker possibly a 15 amp. At 10 amps * 120 Volts, your outlet is capable of running 1200 watts, which is well below what your computer needs. At 15 amps your outlet is capable of running 1800 watts. If you want to figure this out for yourself look at your computer and monitor specs to see what the peak wattage is and subtract it from your circuit breaker amperage * 120 volts. Also keep in mind that your peak wattage is not your typical wattage. Your typical wattage is probably about ½ to ⅓ of the peak. Long answer short you’ll be okay.
