    Best Power Supplies For 3080 Graphics Card

    Nvidia’s GPU Ampere architecture boosts the 3,000 series, including the RTX 3080. The 2080 GPU’s raster engine has seen the most improvements, followed by the RT and Tensor cores.

    If you’re using an RTX 3080 GPU in a typical desktop PC, Nvidia recommends a power supply of 750W. System requirements vary, thus a higher powerful RTX 3080 power supply may need in some cases. Systems using AMD Ryzen 9 / Intel Core I9 or Threadripper CPUs, for example, must have at least 850 watts of power.

    Nvidia says that only the graphics card requires 320 watts of power. This weighs on today’s systems, so let’s take a look at the top ten power supplies for the RTX 3080.
