    Great PSU! Very quiet! Now I wish and wait for graphics card from the 30 series. Best buy needs to move product faster. Charter a ship to China. Target, Costco, and others have figured it out. We need some containers of cards.

    Bought for my new PC build. 2nd time using this PSU brand. Easy to install into pc case. PSU cables are sturdy and with a bit of effort easy to work with. At first it smells a bit, but it goes away.

    Built a new rig. It included a Strix RTX 3080 and an AMD 5950X. I did not want to run out of power and I like lots of headroom. System easily uses 600 watts when gaming. Quiet, cool and powerful. Corsair every time!
