And the HX1000 has an issue with ripple on the +3.3V rail, which can harm some delicate components.
I apologize for the delay. I completely forgot that I received an e-mail telling me that I was mentioned!
Anyway, what has caused you to think that your power consumption might be 1050W? Multiply whatever number you see on your Kill A Watt by .80 for the 80+ Efficiency. That is your approximate power draw being pulled out of the PSU (it's being taken from the PSUs advertised continuous capacity of 1000W).
