Powering Raspberry Pi from 5v power supply

Quick question as I am a complete beginner.

I bought a 5v 200w power supply to power LEDs for a TV ambilight project, and have everything working great. My question is can I power the Raspberry Pi that I am using in this project from the power supply instead of its own 5v brick?
