Mac Pro 5.1 kicking circuit breaker

I recently bought a Mac Pro 5.1 12 core to replace my Mac Pro 4.1 8 core. Does anyone know if these draw significantly more current than the 4.1's? It seems to be kicking my circuit breaker every so often. Never had this problem with the 4.1.

I have to add this was very dirty inside when I got it. Lots of lint like it had been on a carpet. I took out the processor tray and blew off the lint. Have not done a throughout cleaning yet.

Mac Pro, macOS Sierra (10.12), Mac Pro 5.1

A 12 core will draw more power than an 8 core but only a little more unless all cores are loaded.

What is running when the circuit breaker trips?

What else is on the same circuit as the Mac?

The Soundsticks, display and printer. Nothing more than what was on it before with the 4.1. All I do is primarily web surf. I don't do gaming, which I know would use up cores. Nor do I do photo processing. I think this computer was probably used as a server before.

Thanks for the reply.

Mac Pro 5,1 (2010)

Electrical and operating requirements

Line voltage: 100-120V AC or 200-240V AC (wide-range power supply input voltage)

Frequency: 50Hz to 60Hz single phase

Current: Maximum of 12A (low-voltage range) or 5A (high-voltage range)

Operating temperature: 50° to 95° F (10° to 35° C)

Storage temperature: -40° to 116° F (-40° to 47° C)

Relative humidity: 5% to 95% noncondensing

Maximum operating altitude: 10,000 feet

The IEC power cords that fit everything are rated at 13 Amps.

A standard household nominal 120 Volt circuit in the US is fused at 15 Amps.
