why does your amazon link for 1000W PSU when power draw is 1100?
1100Watts at the wall would mean 1000w~DC, a PSU such as EVGA G2 1000w would do this fine. I don't know the corsairs much, but if they come from the same High quality OEM, like superflower or Seasonic, there would be 0 problem doing this.
The only downside of doing 100% load on a PSU, is that you lose 1.5%~ efficiency or so compared to let say, paying an extra 100$ for a 1300w.
