I saw 70C as the maximum permissable temperature for the Athlon64 range! Max P_state (IE, maximum power) is 89W. Min P_state (IE, not asleep) is 35W.

Oddly enough though, the Athlon FX51 doesn't have figures for Stop Grant.

The Athlon XP range were at about 76.8W, so we're only talking about 20W more. I'd figure that any PSU that can comfortably run an Athlon XP will probably ok with an Athlon64.

I would guess that most motherboard designers would take the power from the 12V line, so a PSU that can deliver the power requirements on the 12V line will be a must.

Like any sizing, you should take into account the power requirements for the whole system, not just the processor.
