Customers are saying

Customers are satisfied with the RMX Series RM1000x power supply's performance, ample power capacity, and quiet operation, even under load. Many appreciate the ease of installation, excellent cable management due to its modular design, and the convenient fan control. The power supply's compatibility with various components is also frequently praised. While some users reported an absence of coil whine, it wasn't a widely discussed issue.

    Does the job a expected. All fans and components running at full capacity, just a hefty over price to pay. I could get a GOLD RBG for this price, but my I don't have the tower setup to optimize the RGB use.

    This Power Supply in stablity is Rock solid, previous one I had from a different OEM was having issues when load is heaving in power off or restarting. After changingto RM1000x the system is stable and haven't had any issues and future proof for future upgrades. The Cables quality needs a little more other than all good.

    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.
