      What to look for in a refurbished PC or accessory
    </h3>
    <p class="mb-2">
      Shopping refurbished doesn’t mean you should sacrifice on specs. Look for the following as you browse.
    </p>
    <ul class="mb-4">
      <li class="ml-7">
        <u>Product category:</u> We’ve got refurbished PCs and parts, as well as peripherals and accessories.
      </li>
      <li class="ml-7">
        <u>Warranty:</u> CORSAIR refurbished products feature a 90-day warranty, so look at each product to see what it covers.
      </li>
      <li class="ml-7">
        <u>Compatibility:</u> As with new products, check your PC parts and peripherals to make sure they’re compatible with your setup.
      </li>
    </ul>
  </div>
  <div class="p-4">
    <h3 class="text-2xl mb-2">What does it mean to be “certified refurbished” and is it trustworthy?</h3>
    <p class="mb-4">
    If a product is “certified refurbished”, that typically means that the manufacturer itself has fixed it up and deemed that it’s high-enough quality to sell. CORSAIR has a rigorous product refurbishment process where we test to ensure each item meets the same performance spec standards as a new product, ensure any applicable firmware is updated, give the product a once-over to confirm good physical condition, and pack it up safely to sell. We also take additional hygienic measures with devices like headsets.
<br/><br/>
Every CORSAIR refurbished product also comes with a 90-day replacement warranty, which means that if anything is wrong upon receipt, we’ll replace it free of charge. <a href="/explorer/gamer/accessories/what-is-a-corsair-certified-refurbished-product/?srsltid=AfmBOopTChIzBQrEZfV0bIOfT0PkJMJ1D4rpGJ0SlR0OusZTlD_22KAX" class="custom-link">Read more about our refurbishment process</a> on the CORSAIR EXPLORER blog.
