Things to consider when finding the best PSU Prime Day deals

  • Always read the customer reviews for honest insight into how the PSU performs. Ratings can also give an indication as to how popular they are, so check out the number of reviews it has alongside the average rating.
  • Check your chosen PSU at other retailers, as they may have even better deals. Just make sure you don’t end up paying more with shipping costs.
  • Always check the return policy so you’re not stuck with something that doesn’t work or isn’t compatible.

How long will the PSU Prime Day deals last?

Amazon Prime Day is running from 16th – 17th July this year, so you get 48 hours to score the perfect PSU for you. With the sale just around the corner, we’ve already started to see some great deals start to trickle in but you’ll have to wait for the 16th itself for the best of the bunch.

What to look for in a PSU

  • Power Output and Efficiency: Consider the power output and efficiency rating of the PSU. Ensure that the PSU has sufficient wattage to meet the demands of your system components, and look for an 80 Plus certification for higher energy efficiency. A great tip would be to use a PSU calculator website and input your system configuration. The calculator will then roughly estimate your system’s power draw. Ensure that the PSU you’ll be getting has a good amount of headroom over your system’s power draw.
  • Modularity: Pay attention to the modularity of the PSU. Modular PSUs allow you to connect only the necessary cables, reducing cable clutter and improving airflow within your PC case. Semi-modular or fully modular PSUs offer greater flexibility in cable management. Although fully modular or semi-modular PSUs are not required, they still offer a solid option, especially when you want to be neat and tidy with your PC build.
  • Connectors and Cable Length: Ensure that the PSU has the necessary connectors to support your components, such as CPU power, GPU power, and SATA power connectors. Check the cable length to ensure compatibility with your PC case and components.
  • Build Quality and Reliability: Look for PSUs from reputable brands known for their reliability and build quality. A reliable PSU with high-quality components will provide stable power delivery, protect your components, and have a longer lifespan. Brands that are not known for PSUs might cause issues within your system, and worst of all, some generic PSUs tend to catch on fire or literally explode if given a heavy load.
  • Noise Level: Consider the noise level of the PSU. Look for PSUs with features like a silent fan mode or low-noise fans to minimize noise output, especially during idle or low-load situations.

Final Word

PSUs are very important since they tie your system altogether. A bad PSU choice can result in catastrophic failure, often damaging hardware. It’s better to be sure by checking these factors: Power Output and Efficiency, Modularity, Connectors, and Cable Lengths, Build Quality and Reliability, and Noise Level. Once you’ve checked all of these, you’ll have a worry-free experience even when using your PC to the fullest of its extent.
