Antec HCP 1200W PSU Can Handle Quad SLI GTX 580 OC Stressed by FurMark

Here is video showing four overclocked MSI GTX 580 in a 4-way SLI stressed by FurMark 1.8.2. The CPU is stressed by Prime95. According to the power analyzer, the power consumption of the whole system is around 2200W. The thing that remains unclear for me is that only one PSU is used to power the whole system. Okay, the PSU is an Antec HCP (High Current Pro) 1200W but 2200W is nearly twice the power of the Antec PSU. On the PSU, we can read: AC input: 100V-240V/15A-7A. For an input voltage of 240V, the maximum current is 7A: 240×7 = 1680W. We are still far from 2200W. Seems the 2200W are wrong or simple the HCP 1200W is a real kick-ass PSU! If someone can bring a clarification about this video…
