I wanna know how many watts will my PC components use max.
PC:

500gb western digital caviar blue
DVD RW
MSI Z77A G43

This is the best tool that I know of for finding what you need in wattage.

This gives the minimum voltage for your PSU (Power Supply Unit) of 271w with the processor overclocked.

^ It's actually probably a bit less than that.

This is with an overclocked i7 965 and as they say they are using 50-100 watts more than an average system.

This is also with an i7 965 but not overclocked.

I would say with your lower power CPU you are probably pulling around ~200 watts at load if you are not overclocking.

I already have an Antec HCG 620W. I just wanted to know the peak load wattage of my system. Even though my system uses under 300W at max load a 400W high quality unit would work as well but i would rather have more than enough so that my unit could live longer
