If anyone has an SP20 Jackson, I'm wondering what it REALLY pulls.  They said 1100-1200W in the specs.  Is that TDP of the unit itself?  Is that an at the socket measurement that includes at least 10% loss in heat by the power supply so you only need a 1000W power supply?  Is it a general recommendation of total power supply wattage that fails to take into account 3V and 5V rails?  Or is it the actual amount of electricity that you will need to provide on just the 6-pin graphics card style hookups?  I kinda need to know so I can buy the right power supply.
