What is the 8-pin power connector on motherboard?
The 8-pin connector is literally designed as two of the 4-pin connectors put together. It is entirely possible to just plug the 4-pin connector in the 8-pin slot. It won’t damage anything, but the motherboard will detect the difference and either not start up at all, or run in a VERY restricted mode.
What is the 8-pin ATX connector for?
Can be used to connect to a six or eight pin socket on a video card to provide additional 12v power. Most commonly used to power hard drives and optical drives. These are mostly often used for fan connections in modern system, but in the past they were used for hard drives, optical drives, and many other devices.
Are all 8-pin PSU connectors the same?
4 Answers. 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.
Can I use a 4pin CPU power in 8 pin?
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.
What is the difference between ATX12V and EPS12V?
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.
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. “
Do I need both 8 pin CPU power connector?
You have to plug in the 8pin connector. If you’re going to overclock the cpu plug in both.
Is CPU 8 pin the same as PCIe 8 pin?
no as the pin shapes are different so you cpu 8 pin will not fit into a 8pin pci-e port.
Is 8 pin enough for CPU?
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 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.
Do I need 4 pin ATX?
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.
Can you connect EPS 12V to EPs 8 pin?
You can’t connect male PCI-E 8-pin to EPS-12V because 2 male pins on PCI-E as the top edge joined together and the corresponding pins on PCI-E does not have a slit for that. As said, I have successfully converted EPS extension cable for PCI-E by swapping the color wires and cut a slit on the female connector.
Can a 12V power supply be connected to an 8 pin motherboard?
In fact it is the cable itself that swap 12V pins and GND pins to comply with the mother board pin arrangement. Unfortunatelly it’s not true that you cannot connect PCIe 8-pin plug to EPS-12V (EATX) motherboard slot.
Is the EPs 8 pin standard for PSU?
The EPS 12 volt 8 pin connector is also a standard, part of a sub standard based on ATX 2.2 standard. The DELL EPS 12 volt 8 pin connector does not comply with the EPS standard, and has only 6 out of the 8 pins used. I am not aware of Dell having a design standard for PSU’s. A standard would typically be governed and approved by a regulatory board.
What’s the difference between EPS12V and PCIe power supply?
Note the top left connector on the EPS 12V is squared off, while that on the PCIe is rounded off in the image before.Essentially differences like that are to prevent you from plugging in a PCIe connector into a EPS12V. There may be other differences, but I don’t have these connectors on hand/
