A Corsair AX 750I should be enough.
I also tested a 850 Watt.
I only have rock solid components.
Mobo Asus Sabertooth
Corsair AX 750i PSU
Kingston RAM
Noctua Heat think
Sapphire tricool GPU
Believe me its the FX.
The FX only has 4 FPU`s but 8 physical CPU cores and since seti app uses mostly FPU you don`t need a calculator.
There is no room left for OS specific operations.
That`s why i usually run seti on 4 cores only and it is fully loaded.
I can encode HD video on 8 cores for 24 hours without any issues cause its not FPU bound.
CPU dont exceed 55°C.

Nothing new here, just support of prev conclusions.

And here advantage of STT finally appeared. With sleep quantum only ~15ms STT remained on ~4-5ms range.
