You can easily identify whether you need a 4-pin, 8-pin, or both cables by checking the specifications of your motherboard. How To Check Whether You Need A 4-Pin or 8-Pin CPU Cable? The CPU pin connector requirements vary among different motherboards, and based on this variation, you can determine the number of necessary CPU connectors. This article helps you to figure out the differences between CPU and GPU cables. Stay clear between the 8 Pin CPU and 8 Pin GPU cables both cables are different. Using the Intel Core i9 13900K processor in conjunction with the MSI MAG Z690 Tomahawk WIFI motherboard requires two 8-pin EPS connectors from your Power Supply to supply the necessary power. Therefore, a single 4-pin or 8-pin connector alone cannot provide the required power for this CPU. It is recommended to check your CPU’s power requirement before using the CPU connector because you may need both 4 Pin and 8 Pin connectors in some instances.Ĭonsider the example of the Intel Core i9 13900K processor, which has a maximum power consumption of up to 253 watts. ![]() On the other hand, the high-end overclockable CPUs require higher than 155 watts of power, and you need the 8-pin EPS connector for these CPUs. When Do You Need 4 Pin & 8-Pin CPU Connector?Īs explained, the low-end affordable CPUs require less than 155 watts of power therefore, the 4 Pin connector is sufficient for these CPUs. This table explains the difference between the 4-pin and 8-pin CPU cables now, we will understand when we need which cables. The high-end CPUs with a TDP higher than 155W need the 8-pin EPS connector. The low-end CPUs with a TDP under 155W need the 4-pin P4 connector. The 4 Pin connector can supply a maximum power of up to 155 watts The 8 Pin CPU connector can supply power up to 235 Watts. 4 Pin Cable For CPU 8 Pin Cable For CPU The 4 Pin connector for the CPU is known as the P4 connector The 8-pin connector for the CPU is known as the EPS connector. So you won’t face any issues while installing newer or older CPUs. That’s why modern Power Supplies mostly come with multiple 8-pin CPU connectors, which can be split into 4+4 pins. But modern CPUs are overclockable and require lots of power to function smoothly. The old power supplies mostly come with a 4-pin CPU connector because old CPUs doesnt require a lot of power. ![]()
