The cable that connects the CPU to the power supply is usually called a CPU power cable. Most modern motherboards use either a 4-pin or 8-pin connector, often labeled as 'CPU' or 'EPS.' This cable delivers dedicated power from your power supply unit (PSU) to the processor, helping it run efficiently. When shopping for CPU cables, check your motherboard's manual to see which connector type you need. Walmart offers a variety of CPU cables and extension cords to fit different setups, so you can find what works best for your build.

Whether you need a 4-pin or 8-pin CPU cable depends on your motherboard and processor.

• Many entry-level or older motherboards use a 4-pin connector.
• Most modern boards, especially those for gaming or high-performance systems, require an 8-pin connector or even two 8-pin connectors.

Some motherboards feature two CPU power cable connectors—usually two 8-pin sockets—to support high-performance processors or overclocking.

• This allows for extra power delivery, which can be important for demanding CPUs.
• It's not always required to use both connectors, but doing so can help with stability during heavy workloads.

Yes, CPU and GPU cables are designed for different purposes.

• CPU cables (often labeled as EPS or CPU power) supply power to the processor.
• GPU cables (usually labeled PCIe) deliver power to your graphics card.

If your CPU cable isn't long enough for your PC case, you can use a CPU power extension cable. These cables plug into your existing CPU power cable and add extra length, making it easier to reach the motherboard connector in larger cases.

• Choose an extension that matches your connector type (4-pin or 8-pin).
• Look for cables with durable insulation and secure connectors.
