  • Modular vs Non-Modular PSU: Comparing modular and non-modular PSUs, a modular PSU includes removable cables for neater and simpler installation. All of the cables on non-modular PSUs are fixedly attached.
  • Wattage: The PSU’s maximum power output is represented by its wattage. It is crucial to select a PSU that can produce more power than your system requires because this leaves headroom in case your system ever has to be upgraded.
  • Verify that the PSU’s power rating is sufficient to support your GPU. As a general rule, choose a power supply unit (PSU) with a wattage rating that is at least 25% higher than the power needs of your GPU.
  • Size: PSUs are available in a range of sizes, from compact (SFF) units to large (ATX) units. Make sure the PSU you select will work in your system.
  • Nvidia or AMD have validated some PSUs for usage with their graphics cards. If you own a graphics card from one of these manufacturers, check for a power supply that has the appropriate certification.
  • Warranty: A one- or two-year warranty is commonly included with PSUs. Some manufacturers offer more longer warranties, although they are typically more expensive.
