You cannot, however, use any 8-pin PCI-E cable to power the motherboard. These cables are solely used to power graphics cards which are plugged into a PCI-E slot. As with the ARX-12V cable, it is possible for your power supply to have more than one such cable and some video cards will require two of them.
Can you use PCIe power for CPU?
By specification each PCIe connector could deliver up to 75W at 12V. This means if CPU is on PCIe card and consumes less then 75W then could be powered (reason why GPUs and USB-C cards have PCIe power connector). But, CPU on motherboard CANNOT be powered using PCIe! At least it is not intended to.
Is PCIe and CPU cable 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 connect GPU power cable to CPU?
8pin for CPU has a 12V wire in the place that PCIe 8pin has ground. In other words you’ll cause a short right as you plug it in.
Can you use PCIe cable for GPU?
The principle behind using a single PCIe cable for a graphics card still applies for models requiring more than two connectors, like the EVGA RTX 3080 FTW3 Ultra. Check your PSU to see if separate cables are recommended; if not, just make sure you’re not surpassing how much power a single cable can provide.
Can you use PCIe 8 pin for CPU?
Nope, You can use any 8 pin labeled “CPU” you want. could possibly lead to an upsetting day.
Are CPU and PCIe cables the same Corsair?
So the Corsair RMX 850W Gold has a total of 5 8-pin ports on the back and none of them are specific to CPU vs Pcie cables. You can plug a CPU cable or a PCIE cable in any of the 8-pin ports of this PSU.
Can I use 8 pin CPU on GPU?
It adapts the pinout of a spare 8-pin CPU power cable (EPS 12V) to that which can be used to power a GPU. This works well for people using dual power supply mining rigs. The otherwise unused CPU power slots can be used to provide VGA/PCIE power to additional GPUs.
Do you need 8 pin for CPU?
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.
Which PCIe cable for GPU?
6-Pin Connector
This means the graphics card will use the PCI Express x16 slot and also draw power directly from the PSU (Power Supply Unit).
What is a PCI cable?
The PCI Express x16 connector is used primarily for high speed data transfer between the graphics card and a motherboard. However, the connector has a handful of pins that allow it to provide up to 75 watts of power through motherboard.
What is a PCI power cable?
PCIe cables are used primarily to provide power to the installed graphics cards and other large and power hungry expansion cards. PCIe cables connect directly from the Power Supply Unit to the installed PCIe Expansion Card; Graphics Card.
How much power can a PCIe cable handle?
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.
How many PCIe cables do I need for a 3090?
If you have two of NVIDIA RTX NVIDIA 3090 installed, then you will need 6 x 8 pin cables. The rest of the common expansion cards like a video capture card, network adapter, sound card, USB hub, etc do not require a PCIe cable.
Can power cables affect GPU performance?
Not true. The gpu has no way of knowing a PSU cannot deliver sufficient power. What happens is the gpu draws the power/current it needs, if the psu cannot provide that amount of power you either get voltage fluctuations or complete psu failure. Voltage fluctuations will give instant stability issues or reboot.
Can I use cables from different PSU?
Mixing cables between power supplies can kill the PSU or kill attached components.The different manufacturers, series, or model cables are exact matches and work fine. In this case, there is no damage.
Are all PSU PCIe cables the same?
Disclaimer: The only difference between Type 3 and Type 4 cables is the pinout of the 24-pin ATX cable; all other cables (SATA, PCIe, etc) are the same.
Are PCIe cables universal?
Only the PCIE side is the modular side that connects into the Power supply is not standard. These will vary by PSU.
Can I use PCIe cable to power motherboard?
Yes. That’s what PCIe power cables are for. They deliver 12V power to PCIe graphics cards. Some graphics cards have a 6-pin PCIe power connector, some have an 8-pin, and some have multiple connectors, sometimes a combination of the two.
Can I use a 6 pin PCIe into an 8 pin?
Yes, you can use a PSU that has one 6 pin and one 8 pin PCIe power cables for connecting to a GPU with two 8 pin sockets using an adapter like this: or this: BUT, be sure that your PSU (power supply) has enough power on the 12V rail to support that much power.
Can I use SATA cable for GPU?
There are 2 extra male sata power connectors available in the system which could be adapted to a PCIe 6pin power connector using an adapter such as this one on Amazon. This would only be needed to supplement the 75W that the PCIe x16 slot can provide and enable the gpu to be recognized.
