Its fully modular design and ease of installation are also frequently praised, simplifying cable management and the overall building process. While some users noted its larger size, the positive feedback overwhelmingly focuses on its reliability and value. The power supply is considered a great option for its price point.

    Decent, not great

    Easy install with correct output levels, but as other reviews I have read online stated there is some fan whine. I am also getting static in both of my M-Audio B-5 monitors which I never had with my original Corsair power supply that was NOT a PLUS Gold model. Next time I'll try another brand.

    Does not have compatibility for any 4 pin CPU motherboard connectors. Only comes with two 8-pin connectors.

      Hi,

      The EPS/ATX12V 8 pin connectors for the CPU may be split into 4+4 - allowing connection to 4-pin CPU power headers on your motherboard. If you have any questions or require any assistance, please contact support via our website and we'll happily assist you.

    Power supply was unresponsive out of the box, and i have already emailed corsair support, but the only thing i have received in 3 days of having this ticket open was that i have sent the email to the wrong department and will be transferred.

      Hello Cody,

      If you received a unit with issues the easiest way to get a replacement when it's been less than 30 days would be to reach out to BestBuy directly, otherwise do go to our site and navigate to the help section to get in touch with the correct team of ours.

    Avoid!

    PSU worked great initially. Failed on me about six months in which led it to frying my RAM and GPU. I can’t get an exchange or return on it from Corsair. Will be going back to EVGA after the fiasco I had.

    I've had this cpu for a little over two years now, its dying already. I would recommend going back to EVGA.
