Things to Consider Before Buying a PSU for GPU
There are a few things to consider when selecting a PSU for your GPU:
The quality of the PSU: Not all PSUs are created equal. Make sure to select a PSU from a reputable brand that produces high-quality products.
Know your power needs: The first thing you need to do before buying a PSU figures out how much power your system will need. You can use a power supply calculator like the one at Outervision to estimate your system’s power usage.
Look for efficiency: A good PSU will be at least 80 Plus certified, meaning it’s at least 80% efficient at converting AC power to DC power. The higher the efficiency, the less power is wasted as heat.
Modular vs. non-modular: A modular PSU has detachable cables, making for a neater and easier installation. Non-modular PSUs have all their cables permanently attached.
Wattage: PSU wattage is the maximum amount of power the PSU can deliver. Choosing a PSU that can deliver more power than your system needs is essential, as this allows for headroom in case you ever upgrade your system.
Make sure that the wattage rating of the PSU is high enough to support your GPU. A good rule of thumb is to select a PSU with a wattage rating of at least 25% higher than the power requirements of your GPU.
Size: PSUs come in various sizes, from small form factor (SFF) units to full-size ATX units. Make sure to choose a PSU that will fit your case.
Certification: Some PSUs are certified by Nvidia or AMD for use with their graphics cards. If you have a graphics card from either of these companies, look for a PSU with the corresponding certification.
Warranty: PSUs typically come with a one- or two-year warranty. more extended warranties are available from some manufacturers, but they usually come with a higher price tag.
