When building your new PC, the power supply unit (PSU) will provide power to all connected components. Be it your motherboard, CPU, RAM, SSDs, GPU, and case fans. They all draw power through the PSU. It’s vital to spend a good amount of money on the PSU and purchase one from a reputable brand to ensure you have adequate protection and it’s reliable for daily use. This is the only barrier between the national grid and your expensive PC parts.
The AMD Ryzen 9 9950X is a seriously powerful processor and can suck up to 200W of power through the motherboard. Install a powerful graphics card and you’re easily able to surpass 600W with everything factored in. 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 a PSU for you.
