Can I use a higher-power power supply?

Yes, a power supply can generally have a higher power rating (wattage).

A more powerful power supply does not automatically deliver more current; it merely provides the maximum available power. The connected device determines how much it actually draws.

Important details for operation:

Current consumption: A device rated for 50 W, for example, will only draw the required 50 W even when connected to a 1000 W power supply.

Voltage: This must match the device's requirements exactly. If the voltage is too high, the device may be damaged.

Current (amperage): The amperage rating of the power supply must be equal to or higher than what is required by the device.

Advantages of a more powerful power supply:

Efficiency: Power supplies operate most economically (often between 40% and 70% load) when they are not running at their limit.

Noise level: A power supply that is less heavily loaded usually stays cooler, and the fans spin more slowly or not at all.

Expandability: You still have power reserves for future, more powerful components.
