Customers are saying

Customers love the RMX Series RM1000x power supply for its overall performance and ample power capacity. Many appreciate its quiet operation and the ability to fine-tune the noise level. Users also find the cable management to be clean and the installation process easy, with the modular design contributing to a tidy case. A small number of users reported no coil whine.

    Silent PSU and was a decent upgrade from my 850w which was also Corsair branded. I may have gotten accidentally pricematched to a different PSU now that I'm looking at the design but I do not mind the upgrade.

    Psu is quality, runs 13700k and a 3090 without issue. Fan is quiet or silent. Oem cables are nice and can have combs added to tidy up looks.
