What is 8 pin PCI Express power connector?
This connector is used to provide extra 12 volt power to PCI Express expansion cards. Many video cards draw significantly more than 75 watts provided by the motherboard slot, so the 6 pin PCI Express power cable was created.
How much power does 8 pin PCIe have?
150 watts
The PCI Express slot of the motherboard can provide up to 75 watts to the graphics card. 6-pin power connector can provide up to 75 watts. 8-pin power connector can provide up to 150 watts.
Are all 8 pin PCIe 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.
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.
How much power does an 8 pin use?
8-pin connectors have 4.2mm pitch and can deliver up to 150 watts, twice the amount that a 6-pin connector is capable of. If a 6-pin connector is plugged into an 8-pin slot, the GPU will attempt to draw more power than that cable is rated for, resulting in a fire hazard.
How much power does an 8 pin CPU connector provide?
The 8 pin connector can carry up to 150W of power from the source to the sink (read: source is PSU, and the sink is the graphics card). In the same way the 6 pin connector is designed to safely carry the current for up to 75Watt.
Does my GPU need 2 PCIe cables?
The answer to this question is a resounding YES! You do need to have all the pins connected in order for the graphics card to work. If your graphics card has 2 x 8 PIN requirements. Then, well, you need to provide it with 2 x 8 Pin PCIe Cables coming in from the Power Supply Unit.
Do graphics cards need two PCIe cables?
More Than One Power Connector on GPU On most mid-high end cards, you can expect to find more than one power connector. An 8-pin connector and a 6-pin connector. You can’t use a single PCIe cable for both connectors. In this case, you will need two PCIe cables to power the graphics card.
