![]() This power is enough for older motherboards with built-in graphics processing units (GPUs). If you use an ATX power supply unit (PSU), its 4-pin CPU connector will provide more or less 108 watts of power. How Much Power Does a 4-Pin CPU Connector Provide? A PSU with more power can efficiently run a motherboard with less power. Just split the 8-pin connector into two 4-pin connectors and connect either of the halves to the motherboard of your computer system. If you have such a motherboard and an upgraded power supply unit (PSU) with an 8-pin CPU cable, then don’t worry. This power is divided into parts for your CPU, RAMs, SSDs, and other devices. Most older motherboards have a 4-pin ESP motherboard port and use a 4-pin CPU power plug or cable for switching on. You can use an 8-pin CPU cable for a 4-pin CPU, which will work without any problems. If you have a CPU with more than 155 TDP, then you need this ESP connector.Ĭan I Use 8 Pin CPU Cable for a 4-Pin CPU? The maximum capacity of this connector is 234W. This connector is used to supply current to your CPU. The 8-pin connector is called the ESP connector. Most of the low-end CPUs and high-end GPUs require this PS4 connector. The maximum current supply through this connector is 155W. This connector is used for both motherboard (CPU) and GPU. This is to fulfill the power needs of more hardware connected to it and keep it as cool as possible.Ī 4-Pin connector is also known as a PS4 connector. And the reason behind this is more paths on their PCB (printed circuit board). On the other hand, nearly all of the latest motherboards require an 8-pin CPU power plug or connector cable. The other reason was a bit technical that motherboards with a 4-pin connector did not have more electric paths on their PCB (printed circuit board). It was because the older hardware could not connect more devices to it than the latest ones. The 4-pin CPU power plugs were used with the older motherboards. On the other hand, we suggest you upgrade your power supply unit because it will benefit you in the future, especially when you want to increase the number of devices connected to your computer system’s motherboard. This cable will connect to your PSU’s 4-pin connector and convert it into an 8-pin connector. A 6-inch adapter cable should be long enough for connection. In this case, instead of buying a new power supply, you can use an adapter cable. You may have upgraded a motherboard that requires an 8-pin CPU power plug, but your power supply unit (PSU) has either a 4 -pin connector or a 6-pin or both of them. Not only will your CPU consume this power, but also the RAMs, SSDs, and other devices. It is the only way to provide sufficient power demanded by your PC motherboard. In case your computer system motherboard has two 8-pin CPU power plugs or connectors, then you must connect both of the 8-pin cords to your motherboard. ![]() But if you have hardware requiring more power, you must connect an 8-pin CPU power plug. If you have a low-power CPU installed on your motherboard and a lesser number of memory modules (RAMs), storage devices (HDDs or SSDs), and other USB devices, then a 4-pin power plug will work. In this way, you can join as many devices to your motherboard as possible because your motherboard will have enough power to run them all except for your graphics card (also known as GPU). If your motherboard has an 8 + 4 pin power connector, then we will recommend you connect both of the CPU power plugs. Do I Need Both The 8 Pin and 4 Pin CPU Power Plug? We will also discuss the need for a 4-pin and an 8-pin CPU power plug, so you can choose the best option for powering your computer system’s motherboard. In this article, we will help you understand what your CPU power needs are and how you can economically fulfill them. On the other hand, the latest motherboards require an 8-pin power connector to power the powerful CPU and other internal and external computer devices. Older motherboards require a 4-pin CPU power plug or power connector for powering all the hardware connected to your computer’s motherboard. ![]()
