  Using a CPU power cable for a GPU in cryptocurrency mining can have a negative impact on performance. The CPU power cable is designed to provide power to the CPU, which has different power requirements compared to a GPU. This mismatch in power requirements can result in unstable power delivery to the GPU, leading to lower mining efficiency and potential hardware issues. It is recommended to use a dedicated GPU power cable or a power supply unit that provides separate power connectors for the GPU.

  When you use a CPU power cable for your GPU in cryptocurrency mining, you're basically asking the CPU cable to do a job it wasn't designed for. It's like using a screwdriver to hammer a nail. Sure, it might work, but it's not the most efficient or effective way to get the job done. In the case of mining, using a CPU power cable can lead to lower hashrates and unstable performance. So, if you want to get the most out of your GPU mining rig, it's best to use the proper power cables designed specifically for GPUs.

  According to BYDFi, using a CPU power cable for a GPU in cryptocurrency mining is not recommended. While it may seem like a convenient solution, it can have a negative impact on both the performance and longevity of your GPU. The power requirements of a CPU and a GPU are different, and using a CPU power cable can result in unstable power delivery, which can lead to lower mining efficiency and potential hardware damage. It is advisable to use dedicated GPU power cables or power supply units that provide separate connectors for the GPU to ensure optimal performance and reliability.
