These power cables deliver critical +12V voltage directly to the processor, ensuring stable operation under varying workloads. The 4-pin CPU power connector, also known as the P4 or ATX12V connector, was introduced to supplement the main 24-pin ATX power supply by delivering additional power specifically to the CPU. Always match the cable to your motherboard’s CPU power socket—check your motherboard manual for specifications. A 4-pin or 8-pin CPU power cable is a critical component in modern computer power delivery systems, designed to provide stable and sufficient power directly to the processor. These connectors ensure reliable operation, especially under high-performance workloads such as gaming, video rendering, and overclocking. The 4-pin CPU power connector, often referred to as the P4 or ATX12V connector, was introduced to supplement the main 24-pin ATX motherboard power connector by delivering additional +12V power directly to the CPU. This configuration is commonly found in older or lower-power systems where the processor does not demand excessive electrical load. This connector features a square-shaped design with two black plastic pins (hollow guides) that prevent incorrect insertion, ensuring foolproof alignment. It delivers up to 288 watts of power (4 pins × 12V × 6A), though real-world delivery is typically lower due to safety margins and cable quality.

If you are building or upgrading your own PC, you might be wondering what the difference is between a 4-pin and an 8-pin CPU power connector. These connectors provide power to the CPU, which is the brain of your computer. A 4-pin CPU power connector is the standard connector for most CPUs. It has two yellow wires and two black wires, and it plugs into a 4-pin socket on the motherboard. A 4-pin connector can deliver up to 192 watts of power, which is enough for most CPUs. An 8-pin CPU power connector is an optional connector for some CPUs. It has four yellow wires and four black wires, and it plugs into an 8-pin socket on the motherboard. An 8-pin connector can deliver up to 384 watts of power, which is twice as much as a 4-pin connector. The first thing you need to do is to check the specifications of your CPU and motherboard. If your CPU and motherboard both support an 8-pin connector, then you should use it for optimal performance. If your CPU and motherboard only support a 4-pin connector, then you have no choice but to use it.

Thanks for reply So if am paired h110 mobo with i3 7100, it will not bottleneck also if I am using gtx 1050ti and my PSU is corsair vs 550watt That would not be possible. that motherboard will support that cpu but you would have to use a last gen core i3 and then update the bios, which I'm guessing you don't have. so yes, get the B250, but if you want my input, Here is a motherboard that will support 7th gen intel processors right out of the box. https://www.newegg.com/Product/Product.aspx?item=N82E16813130986 I personally have never had any issues with MSI, so yeah... ... Thanks guys I am confused for motherboard, which one is better and the difference of 4pin 8pin.

Should I use my PCI 4 pin power? Is there any way around this? Thanks for your help! Your 8 PIN CPU connector should SPLIT in half into 2 FOUR pin connectors. Try doing that. DO NOT try using a four pin PCI ... It might be an 8pin, it should be labeled EPS or CPU power. You should be able to split it. Check https://seasonic.com/product/s12ii-430/ the Cables tab My bad. Apparently this model has seperate cables for 8,6,and 4 pins... My CX500 doesn't have a 4 pin CPU power plug. The CPU plug on the CX500 has 8 pins. How do I connect this? Should I use my PCI 4 pin power? Is there any way around this? Thanks for your help! Your 8 PIN CPU connector should SPLIT in half into 2 FOUR pin connectors.
