Default power consumption

If the power supply of a computer is say 300W, does it matter if the actual power consumption is lower? I am building a new PC and i know very little about the power supply type matters.

Basically would i need to find the power consumption for each device, add it all up etc, or could i just buy a nice big 700W power supply and use that?

You can usually ballpark the number depending on your setup, just make sure you get a better power supply then the one that comes with your case. Thermatake and Fortron I hear are good companies. But like I said, it depends on your setup, most non-SLI setups usually get a 400-450W and run with no problems and plenty of room for future parts without having to worry about PSU problems.

Yes, Fortron, FSP, Sparkle are the same company.

You can use anything more powerful than you need. You should get a PSU with good 12V Ampage over watts. You should always have a more powerful PSU than needed - also helps with future upgrades.
