Is it safe to install a higher wattage power supply in my computer?

It’s quite safe to install a power supply with a higher wattage rating than the power supply it’s replacing. The wattage rating only indicates what the power supply is capable of. Actual power use is determined by the computer’s power requirements.

Is it better to have a higher watt power supply?

The main duty of a power supply is to provide power to the connected load (devices). The more robust the application, the more power required and the higher the wattage you’ll need from the power supply.
