      Hi ChaoticTaco,

      We're sorry to hear that the PSU stopped working so soon. Could you see if the power supply itself can still power on? Try performing a paperclip test to see if you can jump the power supply itself? If you'd like assistance with performing the paperclip test, please feel free to reach out to our support team: support.corsair.com

    Corsair Knocks it out of the Park

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Corsair has a history of making affordable products that are of high quality. I've used their PSU for years now and never had an issue. I love the modular ability of this PSU, it makes the system look clean and allows you to expand later if needed. The PSU is quiet and I've had no issues with it thus far. Here is a video of me unboxing it and installing it. https://youtu.be/lW7cpiEVJkE

    Great power supply, a bit large

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Using it as I type this review, it was a moderately easy install, except for the fact that it is quite big, and can be a tight squeeze to OEM cases. The modular feature is a relief, but the cable labeling could be more clear. Not recommended for newbies, but if this is not your first PSU install, have at it!
