If you're using a pretty poor power supply, is there a chance that it might not be supplying enough power to your graphics card, and thus leaving you with sub-par performance?

Well, not really sub-par performance. It will either fail or not; it won't run slowly. Getting a better PSU will not increase your framerates, but it may keep you from crashing.
A poor PSU can definitely damage your components with power surges etc, and it probably won't supply the wattage it advertises. Get a decent, mainstream, branded PSU.

One of the indications of inadequate power is a system that will run a 2D desktop with no problems, but cause seemingly random reset/reboot cycles while gaming.

Power requirements of graphics cards can more than double under 3D gaming loads.
