3.4 Installing a PSU Flashcards
What is the primary function of a PSU?
To convert AC input (120V/230V) to DC output (3.3V, 5V, 12V) for computer components.
What is the advantage of a modular PSU?
Detachable cables improve cable management and airflow.
What are the main connectors included with a PSU?
24-pin motherboard connector, 8-pin CPU power, 6+2 PCIe, SATA power, and Molex.
What is the purpose of the 24-pin PSU connector?
To supply main power to the motherboard.
What type of PSU connector powers the CPU?
An 8-pin CPU power connector.
What is the 6+2 PCIe connector used for?
To power graphics cards, supporting both 6-pin and 8-pin configurations.
How should a PSU be positioned in a case?
With the fan facing downward for proper airflow.
What steps are involved in connecting the PSU?
Secure the PSU, route cables, connect 24-pin to the motherboard, 8-pin to the CPU socket, and additional cables to devices like hard drives or GPUs.
What is the purpose of cable management during PSU installation?
To improve airflow, aesthetics, and prevent cables from obstructing fans or components.
What should you check regarding voltage when installing a PSU?
Ensure the PSU is autosensing or set the correct voltage manually for international setups.
Why is it recommended to choose a PSU with higher wattage than required?
To provide overhead for future upgrades and ensure stable power delivery.
How are SATA power connectors used?
To power storage devices like SSDs and hard drives.
What is the function of Molex connectors?
To provide power to older components and peripherals.
Why is zip tie usage important during PSU installation?
To organize cables for better airflow and avoid obstructing components.
What is a key benefit of autosensing power supplies?
They automatically adjust to regional voltage, reducing the risk of hardware damage.
