To determine if your power supply can handle a graphics card, check the card's power requirements, usually listed in watts. Then, compare it to your power supply unit's (PSU) wattage rating. Add the power needs of other components (CPU, RAM, etc.) to ensure the total is below your PSU's capacity. Finally, make sure your PSU has the correct power connectors for the graphics card. Using a power supply calculator tool online can also simplify this process.
