Does it exist??

[The Astroman]

Is there a program out there which will tell you the number of Watts being used and the number of watts left on the PSU??? Thanks!

I don't think that such a program exists. And even if there's a CPU watt meter, it could only estimate the power consumption.
However, you can calculate your system max power consumption here: http://takaman.jp/D/?english
