i have a 300 watts psu at the moment and my video card recommends 350 but my computer seems to work fine. i guess 400 watts will do.

Processors use between 65W and 120W depending on model. So yes, they do use quite a bit of power. The other power hog in the system is your graphics card, if you have one that requires a dedicated power connector, it is using around 90W, most high-end graphics cards require a power supply of 350W or more. The new generation of graphics cards require even more power, in the area of 150W+
Overclocking really has nothing to do with it but the better the power supply, it does help. It really depends on the type of processor you have that will determine how much you can overclock it. Overclock it too much and the system will become unstable. Plus, you may need to add extra cooling as the faster the processor runs, the hotter it gets, anything over 55C is unsafe.
The main thing you need a better power supply for is a better graphics card and in some cases to run your motherboard (my motherboard required a molex connector) and a better processor though the newer processors are using less power. Also keep in mind that the more Watts you get in a power supply, the more heat it will generate.

Most of the components inside PC will run at fixed voltage. By increasing Wattage means that it will be able to supply more current for your components. That means that you can have several boards inside PC that can be driven from this power supply. DVD drives, video cards, multiple harddisks etc. without any problem.
Along those lines, if you overclock your processor, it will require more current to run. Voltage will not change, but the processor will require more current to operate properly.

The more wattage, the more stuff you can run (hard drives, cdroms, add-on cards, etc.) The voltage on a CPU is not very much (under 2V) so that's not much of an issue.
