The problem with wattages is that they're not very reliable for brandless PSUs. A 400 watt quality PSU can actually run a lot of high-end stuff (ok, no tri-SLI 8800 Ultra) with some effort, but a brandless one may just as well crash then burn then explode. Also, you see all those 1kW+ PSUs when there is no system at stock that can only work with that much power.

Right on RTB,

I found an Antec 1000W Power Supply between 80%-85% efficient.  So you can only put a load of 800w on the PSU.

8 Cores at 4.0GHz + 8800GTX = 623W

8 Cores at 3.2GHz + 8800GTX = 470W

4 Cores at 3.0GHz + 8800GTX = 241W

P.S. just the E6800 processor under load uses 67W, E6300(B2) uses 45W, E6300(L2) uses 37W

False. The wattage number is how much watt it can support after conversion, so if a 1000W PSU is 80% efficient at 1kW, then it takes 1000*(0.8)^-1 or 1.25kW from the socket. Also note that the efficiency depends completely on the load, for a general PSU it's the most efficient around 50% of its maximum wattage.
