3.5 Power Supply Connectors Flashcards
What is the purpose of the 20+4-pin connector on a power supply?
To ensure compatibility with both 20-pin and 24-pin motherboard power connectors.
What type of connector powers a CPU?
A 4-pin, 6-pin, or 8-pin CPU power connector, often in a 4+4 configuration for flexibility.
Why are PCIe connectors used in power supplies?
To provide additional power to high-performance GPUs that exceed the PCIe slot’s wattage limit.
What is a Y adapter used for?
To split one power connector into two or convert one type of connector to another.
How do you distinguish a SATA power connector from a SATA data connector?
A SATA power connector is 15 pins and longer, while a SATA data connector is 7 pins.
What connector type provides power to SATA drives?
15-pin SATA power connector.
How does a 6+2-pin PCIe connector work?
It combines a 6-pin and a 2-pin connector to create an 8-pin connector for modern GPUs.
What is the function of a Molex connector?
To power legacy IDE/PATA drives and older optical drives.
What advantage does a modular PSU provide with power connectors?
It allows unused cables to be detached, improving airflow and reducing case clutter.
Why are power supply connectors keyed?
To ensure connectors are inserted in the correct orientation, preventing damage to components.
What is the standard connector for powering a modern motherboard?
A 24-pin connector or a 20+4-pin for compatibility with older boards.
What type of connectors are required for GPUs?
6-pin, 8-pin, or 6+2-pin PCIe connectors, depending on the GPU’s power requirements.
Why might you use a Y splitter adapter?
To expand the number of available power connections when there are not enough PSU connectors.
What precautions should you take when connecting power supply cables?
Ensure proper alignment of keyed connectors and avoid excessive force to prevent damage.
What is the role of the CPU power connector on the motherboard?
To deliver additional power directly to the CPU for stable operation.
