    This replaced my old Corsair 650, and has been supplying the rest of the computer like a champ. Quiet operation just as advertised, and fully modular. Would definitely recommend getting it if upgrading parts.

    Extremely good PSU for a high-end builds. I'm pairing it with an RTX 3090 and so far no problems at all. Cables are very thick though, making it difficult to manage inside the case.

    Had to buy due to my other power supply kicking the bucket, I was blown away by this purchase due to how quiet this power supply. Corsair makes great products.I highly recommend this power supply to anyone in search/need of one.

    Honestly the 850w is just as good I only went with the 1000w cause sooner or later I plan on upgrading and with that beating said I don’t have to worry about buying another psu if needed cause I got the big boy and think it was the best decision!

    Upgraded to this beast to power my upgraded rig. This bad boy puts out plenty of power for my i9-1300K/RTX3090 system. The modular design is great for keeping the cables nice and tidy. I have always had good success with Corsair products.
