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.

    Solid Power Supply

    Solid power supply that's replacing an aging 750w EVGA unit. This PSU is quiet and the fan rarely, if ever, runs, so I haven't had to clean the PSU dust filter on my case. My GPU 12-pin GPU connector also hasn't melted (yet). Insofar, solid unit.

    Needed an upgrade to my system that was worth while. This wasn't too expensive and got the job done. Also an A-Tier PSU.

    This little beast powers my new gaming rig in 2025. I don't skimp on PSUs, whereas with some other PC parts you can truly afford to go cheaper. Peace of mind achieved.

    When I upgraded my GPU I needed a power supply with a bit more juice to run my 5080. I hopped on BestBuy and had this the next day

    I was able to purchase a 5080 and needed a power supply with a Native 12V-2x6 Connector. This power supply works perfectly for my needs.

    I like the clean look of this PSU. The fan is so quiet when not gaming. It can get loud if needed but only on intense games. Really nice quality cables and overall great.

    Just what you need to future proof for AMD or Nvidia GPUs! 6 pcie ports and a 12vx2 port. Let me run a Gigabyte 9070XT with an MSI B850 Max Tomahawk mono and a Corsair Titan AIO 360mm (which took all 6 pcie ports), then I switched to an MSI RTX5070ti and could use the newer 12v power cable (much cleaner to say the least!).
