I'm building my first PC, and I'm unsure how much power supply wattage I need?

My rig:

Intel core I5 4570 3.2GHz Proccessor

MSI-Z87-GD65 Motherboard

Kingston 2x 4GB RAM

Geforce GT 630 graphics card

Seagate Barracuda TB Hard Drive

I'm yet to get a disc drive/ soundcard and because I'm looking to add a few extra's once I'm done and slowly upgrade, I probably want to have a little extra wattage to allow for that in the future.

Thanks :)
