I used the power supply from a computer and everything works great. I was even able to ramp it up to the rainbow code that uses the maximum amount of power that I will be using for hour and a half without problems.
One weird thing, some of the tlc chips get really hot while others stay cool even with the same code pumping through them. I noted that the ones that stay cool actually have internal resistance of about 200k between power and ground pins while the others stay open as I would assume it to be.
