Dear OP, It should run OK.
I have a very similar system, and it pulls ~60w from the wall full load. And that is a 3000+, and overclocked 11% to 2GHz. And a 3.5" HDD. And remember that an 80W PSU can *output* 80w, not draw 80w from the wall. The only thing that may reduce my power draw compared to yours is that the graphics drivers don't work on windows-7 so it is running off the default windows ones, which don't utilise the thing much. But i don't see the IGP pulling 25W+ and i doubt you are stressing it with gaming either.
These PSU calculators are almost all complete FUD.
Also, you may be interested to know that with a relatively modest heatpipe cooler (i'm using the AC freezer), you can run your system completely fanlessly. I peak out around 60*C, after hours of stress testing.
Yet another thing in your favour, the 2600+, whilst it didn't have CnQ (concensus at the time was it made no difference anyway for it), you *could* undervolt it more. Most could only go do to 1.0v, but those without CnQ could hit 0.8v, and without breaking much of a sweat. This is at least true for the s754 version, i believe the same for AM2. So, it is actually better than the versions which support CnQ.
If you are short of power, you should see the hard drive skipping and powering up/down, and stability issues. If you have neither of them, I doubt you have a power problem.
So, in summary, apart from the slowness, you have a pretty awesome system for a silent PC, and should comfortably work with a picoPSU.
