My question is, would i be safe with buying a power supply that exceeds my requirements in power for my components, or can too much power damage my computer in any way?
No, you can not damage your system by having a powerful PSU and a small load.
The PSU will still output the same 12v, 5v or 3.3v regardless of the load (up to the maximum it can handle).
Having a higher wattage PSU means only that it can output higher amperage at these given voltage values (Watts = Volts x Amps).
The more amps it is capable of outputting, the more hardware it is capable of running.
