Yes! His power supplies are 2x1500 Watt. That puts it at 3KW max which is more than a 20A circuit can provide (2400W). The standard outlet is typically rated at 15 amps or 1800W. And the 15A breaker is on one circuit. You can get 20A circuits but they need to be wired for it, and replacing the breaker won't cut it. Assuming his GPU is ~450W (his number) and power supplies are 80% efficient, well that means he's pulling close to ~2400 watts which is super close to the limit of a 20A circuit. 4 * 450 / 0.80 efficiency = 2250W. That doesn't include the power consumed by the CPU or mother board or other things on that circuit. But a 170W CPU would easily push this over 2400W provided by a 20A circuit.
