Which type of power supply voltage supports high-performance graphics cards?

• A. 1.5 volts
• B. 5 volts
• C. 12 volts
• D. 3.3 volts

Answer: (C)

High-performance graphics cards typically require a power supply voltage of 12 volts. This is due to the energy demands of advanced graphics processing units (GPUs), which need substantial power for operation, especially under heavy loads such as gaming or rendering graphics. The 12-volt output is commonly used in PC power supplies to provide the necessary energy levels to components that require higher power draws, including the CPU and graphics cards. In many modern graphics cards, there may be dedicated 6-pin or 8-pin power connectors that also operate at 12 volts, ensuring that the card receives consistent and sufficient power to perform optimally. The other voltage options do not meet the power requirements for these high-demand components. For instance, 1.5 volts and 3.3 volts are typical for low-power components, like certain logic circuits and memory modules, while 5 volts is traditionally used for peripherals and some older interfaces. Therefore, the reliance on 12 volts is a crucial aspect of modern PC design, especially for systems utilizing high-performance graphics cards.
