Do the Phenom 9850 and 9950 really use only about 100w stock?

According to this, it's rated for 125w and 140w, respectively, but actually only uses 100-101w at stock levels. Can anyone confirm that this is accurate?

This would be good for people with crappy boards, like mine, that are rated only for 125w CPUs and not 140w. Even if I get a 125w CPU, it'd be nice to know I have some overclocking headroom. For example, according to that calculator, the 9850 only hits 125w once it's been overclocked to about 3.0.

My guess is that irregardless of what the wattage calculator says, it is likely that if a mobo says it doesn't support the CPU, then the CPU won't run very well in it, if at all.

That's kind of how I feel, too. Not that I'd get the 140w CPU, anyways, since my board doesn't officially support it. But if a board does officially support a 125W CPU (and not 140w), I'm still trying to figure out whether there's overclocking headroom. No one really seems to know for sure.

I have theories of my own, but I was hoping for some technical knowledge.

Careful. The "wattage" that is reported with cpu's specifications is their thermal dissipation power--basically how much heat the cpu puts off at max speed/load. At stock idle, the cpu won't consume nearly that much power, and at load, due to the laws of physics, if the cpu really does put off 125w of heat, it must consume more than that to operate. I have no idea exactly how much that is though...
