    This is my second Corsair psu. I think they’re top notch, if you don’t want to spend money on aftermarket cables, the one it comes with are pretty good.

    I love it! It was time for me to replace my old PSU that had less wattage. I'm glad I decided to upgrade to this one.

    The EVGA supernova wouldn't ship to my house so I got this instead. It works great and provides me with plenty of headroom to upgrade my GPU down the line.

    Typical Corsair Power supply. The only thing I did not like was the fact they got rid of the canvas cable bag and just piled the cables into a seal plastic bag. Otherwise 5 stars

    I am using this for a high end PC build and it works with absolutely no issues. For those not in need of ATX 3.0 I strongly recommend this power supply.

    I know this is an overkill PSU for my machine that doesn't even have a power-hungry GPU, but I bought it for long-term upgradability. Also Corsair customer support has been outstanding in my experience.

    Performance

    Good for non-overclocking logic board

    Good performance, just doesn't include 4pin CPU cable that certain logic boards needs for overclocking. Had to order that cable through Amazon since best buy doesn't offer it. It was only 4 bucks, so nbd. You can use the additional 6 pin CPU cable, but I'm not sure if that would be good for your board as a whole.

      Hi Bird,

      This PSU should come with 3 EPS12V 4+4 connectors for you to use. They are joined as an 8-pin, but can be split to 4-pin. If you'd like assistance, please contact our support team directly: support.corsair.com

    Great psu. My only complaint is that it seems like Corsair intentionally supplys these psu's with cables that have the capacitors soldered in the most inconvenient spots. So if you want to do any real cable management, your going to have alot of trouble making them bend nicely. Then, you have to buy thier individually sleeved cable set which are also really nice but pricey.

    Bought a 2080ti from someone I know & didnt want to deal with online shipping of a psu so I bough this. Great & exactly what I needed. My case is corsair 200r as well which is great it matches perfectly. The pcie cales are kinda fat which means hard to plug in depending on your case but with a some bending theyll work for now. Its not like itlle stop them from working they’re just fat
