You're running over 1800 watts from one outlet, which means your are pulling over 1800 watts from one circuit.

If that's a 120V 15A circuit you are in dangerous territory. You should not run a continuous load greater than 80% of your total available wattage on any given circuit. I'm guessing you are using other electronics on this same circuit and are overloading your circuit. It's going to eventually start tripping. If you have an older house/apartment you have a fire risk of the breaker not tripping at a given heat.

Before you build your first rig, buy your first part, or think about pressing the power button you need to know your power limitations. This is why there are threads and pictures of people with burned out rigs, cables, and components.

You need to shut your rig off until you map your circuits to disperse your load correctly.
