A circuit breaker is a protection device designed to trip when you exceed its rating. If it doesn't trip then you are staying under 15A. Putting bigger breaker wont do anything except create a fire hazard.
A 700W PSU at full load would draw about 6A, give or take. If you are coming close to maxing out your PSU then you should get a higher rated one.
The voltage at the outlet is about 115V nominal, but it will sag under load. How much it will droop depends on quality of the wire, length of the wire and how much current is being drawn. For example, I have a laser printer plugged in to the same circuit as my computer. When printer turns on the UPS switches to battery power because it detects under voltage condition. If you have other equipment on the same circuit as your computer that pull a lot of power then you might be running at slight under voltage. PSU can handle it for short period of time but it could cause additional stress on the components leading to failure.
I suggest getting an UPS for your computer. It will protect you from under/over voltages. Also get something like kill-a watt to see what your voltage and current is at the outlet.

Ok dumb question. (Dizzy moment) How is a 750 watt power supply over kill?
