What is the 4 pin connector on a motherboard?
ATX 12V or the 4-pin CPU Connector
This is the 4-pin connector which supplies electrical current to your CPU and is mandatory to connect in the motherboard provided you are not using the EPS12V connector which is explained below. The ATX12V 4-pin connector is used by a majority of processors be it Intel or AMD.
What is an EPS12V connector?
EPS12V is a special, non-ATX standard adopted by the Server System Infrastructure (SSI) group to provide a more powerful and stable environment for critical server-based systems and applications. EPS12V equipment is not compatible with standard ATX or ATX12V PCs found in homes and offices.
What is the difference between ATX12V and EPS12V?
What is the difference? The EPS12V has always been an 8-pin CPU connector. The ATX12V used to be the 4-pin P4 connector before it transformed into 4-pin ATX12V, then 8-pin ATX12V.
What is a 4 4 pin 12V connector for?
ATX 4-pin 12V Power Connector Pinout
The ATX 4-pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.
Can I use a 4 pin power supply on a 8 pin motherboard?
If your power supply only has a 4-pin connector, it’s still quite likely that you can use it in an 8 pin port. If compatible then it will go in on “one side” of the 8-pin connector. This will likely give enough power, but beware over-clocking.
Do you need the 4 pin ATX connector?
1-9 of 9 Answers. The 4 pin is only necessary if you are doing extreme overclocking, such as LN2. Otherwise the 8 pin will provide all the power you will need.
What is a 4 4 EPS cable?
4+4 Pin ATX/EPS. A hybrid of the 4 PIN ATX12V and EPS 12V connectors that can be split in half or combined to accommodate either the EPS 12V Socket or the ATX 12V socket. Provides additional power to the CPU.
Do you need ATX12V?
This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it. “
Can I use CPU cable for PCIe?
As a belated reply, if you think about it, why would they bother stamping PCIe and CPU on the cables if they were the same? They are definitely not, and generally won’t fit into each other’s plugs, because different pins will be round versus square.
Do you need additional 4 pin connector for motherboard?
Usually you don’t need to connect the extra 4-pin (for a total of 12 pins), which means you only need the 4+4 pin (8 pin total ) connector on your Seasonic PSU. 8 pins are required, the extra 4 pins are optional.
Is the 4 pin ATX power connector necessary?
Do I need to connect both ATX 12v 8 pin and 4 pin?
The 4 pin is only necessary if you are doing extreme overclocking, such as LN2. Otherwise the 8 pin will provide all the power you will need.
Do I need to connect both 8 pin and 4 pin CPU power?
You do not have to plug that extra 4 pin CPU power connector on the board. The 8 pin is more than enough for running the system. You’re totally fine without it. If you’re upgrading to a RTX 3070 or 3080 and a Ryzen 5600X your 650 Watts should be enough since it’s a good model.
What is the extra 4 pin CPU connector for?
Can you use a 8 pin CPU for a 4pin?
Yes, you can use an 8 pin CPU power connector in a 4 pin CPU power socket if there is no obstruction for the four unused pins. The 4 and 8 pin have all 12V on one side and all ground on the other and both latch the same direction with the 12V towards the latch side.
Are EPS and PCIe cables the same?
They are completely different. The EPS connector is meant to supply power to a motherboard cpu socket while the PCI express connector is meant to supply power to a GPU.
Is 4 4 pin the same as 8pin?
Correct. The 4+4pin can also be called an 8pin eps connector and the PCI-E 8pin can also be called a 6+2pin.
Is ATX12V better than ATX?
Another difference between ATX and ATX12V is the power efficiency rating, which determines how much power is pulled from the wall compared to the output of the computer. Some older ATX PSUs have an efficiency rating below 70 percent, while the ATX12V standard requires a minimum rating of 80 percent.
Are all PCIe cables the same?
PCIe Power Cables and Connector Types. There are different types of PCIe power cable connectors and they differ from each other in terms of how much power they can supply to the card. What is this? The number of PCIe cables and the type of connector you need would depend entirely upon the graphics card you install.
Why does PCIe cable have 2 ends?
When you plug in two PCIe power cables from such a PSU, you’ll draw power from each rail separately. So even if your card has a very sharp spike, you’ve reduced the risk that it could exceed the maximum available power.
Is 4 pin ATX necessary?
Do I need to use the +4 pin on the motherboard?
4 pin is for extra stability when overclocking etc. It is not necessary to use the additional 4 pin connector if you’re not pushing the board or CPU too hard. Basic everyday computing and gaming won’t require it.
Is 4 pin enough for CPU?
Do I need both 8 pin and 4 pin?
How can I tell PCIe from EPS?
The way to tell the difference between PCIE cables and EPS cables is that PCIe cables will have a bridged terminal while EPS will not.
