I am trying to calculate the total wattage used. I have the wattage of the floppy drive, hard drive, cd/dvd drive and the power supply only thing i am missing is the motherboard. My computer didn't come with a manual just for the motherboard. I checked online for the manufacturer's site and it doesn't list the volts and amps for the motherboard. so i might be ou t of luck

It's not usually published and it is difficult to measure because you have to operate it with at least the processor/cooler and RAM installed. The main power consumers on the board itself are the chipset and the voltage regulators. 3-phase voltage regulators have the least consumption. 8-phase regulators on high-end motherboards consume a lot more. Boards w/ simple chipsets and 3-phase regulators consume around 15 watts. Those w/ more sophisticated chipsets and 6 or 8-phase regulators could consume more than 20 watts. Intel G33 chipset consumes up to 14.5W while P35 up to 16 watts and 6-8 phase regulators may consume as much.

Well, I dont think you will. Bear in mind that the power supply not only has the motherboard to run, but also CD drives, cooling fans etc. Just buy a 500watt power supply. That should be sufficient.
In answer to your additional detail:
Your motherboard will most likely run from either a 5 volt or 3.3volt feed from your supply. The amps will vary moment to moment, depending on how much work it is doing at that moment in time. I would guestimate that it would use no more than 15 watts (not inlcuding ANY fans here!) So call it that if I were you.

The only place you will find this is from the manufactures web site, and that is if they list the motherboard white sheet specifications. This information is not generally needed. Because the Motherboards operate on multiple voltages its not a big concern, most of the power comsumption comes from periphial devices like hard drives, fans, dvd drives, CD Roms, and other interal add on cards.

I can't say that I've seen the wattage numbers published as the current it draws is a function of the cards you install and the CPU you use. I would check the mfr site (like Intel or Asus).

Gotta check the manual that came with it... check through your system documents.
You can also get the make/model and look at the manufacturers website.
