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.

    Broke my motherboard. Customer service for Corsair is online chat only. Resolution was to send everything to them and wait almost two moths for them to decide if they would compensate ANYTHING and your stuff would be discarded at that time. I’ll never buy Corsair again. After two premature failed AIOs, 2 failed mice just outside of warranty (meanwhile my logitechs have been going for 10+ years) and a failed headset dongle… now this… pass

    Honestly this is one of those items that you hope just works and this one does exactly that. The cables are of high quality and just like other corsair products it has a great warranty.

    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.
