When you build your new PC, the power supply unit (PSU) is what supplies power to all the components connected to it. Be it your motherboard, CPU, RAM, SSDs, GPU, and case fans. They all draw power from the PSU. It is important to spend a lot of money on the PSU and buy one from a reputable brand to ensure you are adequately protected and it is reliable for everyday use. This is the only barrier between the public power grid and your expensive PC parts.


The AMD Ryzen 9 9950X is a really powerful processor and can take up to 200W of power through the motherboard. If you install a powerful graphics card, you'll easily get over 600W, all things considered. So which PSU should you buy? Is a 750W unit enough, or is it better to buy a PSU that can handle more than 1,000W of power? Whether you're building a standard ATX PC or a compact Small Form Factor (SFF) system, we've got the right PSU for you.

Choosing a power supply for the AMD Ryzen 9 9950X

The AMD Ryzen 9 9950X is a power-efficient processor considering it has 16 cores and 32 threads. You don't need the highest capacity power supply on the market to provide enough power, but how much capacity you need depends on other factors, including the graphics card. The GPU can easily draw the most power, so it's best to configure your PC accordingly, taking into account the maximum power draw from AMD, Intel, or Nvidia (depending on the manufacturer).

It is a good idea to calculate the power requirements of your PC and then buy a power supply with enough capacity to run at around 50% for maximum efficiency. This is when the power supply will work best, converting AC to DC and losing as little power as possible.
