What Are Eps12v Cables?
An EPS12V cable looks and works a lot like a PCIe cable, but it does a different job – instead of powering a graphics card, it powers your CPU.
Even though they might seem the same at first glance, they are pretty different. The number and type of pins on an EPS12V cable are not the same as on a PCIe cable.
For example, an EPS12V cable has ground and 12V pins in different places than a PCIe cable. The actual shape of the pins on EPS12V and PCIe cables is also not the same.
So, you can’t swap them out, even if you wanted to, because they usually won’t fit. This is good because using the wrong cables could harm your computer parts and system.
It’s best to use each cable where it’s supposed to go to keep everything running smoothly and avoid any problems.
Are Eps12v And Pcie Cables The Same?
Even though they seem similar and do somewhat similar jobs, EPS12V and PCIe cables are different. When setting up your computer, it’s important to use the EPS12V cable for your CPU and the PCIe cable for your GPU.
But don’t stress too much – even if you mix them up, these cables won’t fit where they’re not supposed to go.
If you’re connecting your PCIe cable to your GPU and it feels tricky, double-check that it’s suitable. Now that you know how to give power to your CPU correctly, explore the best gaming CPUs for possible upgrades.
