    WE replaced our old one that we had on our home sound system and it has worked without any issues. We have it so it puts the system to sleep. It is hooked up to the sound system and our theater system downstairs. FYI just don't buy the least expensive buy quality that will last!!!!

    After buying the RM1000e and having the electrical arcing sound issue that the entire E series has had since the first where produced(which i didnt know before buying) but this RM1000X has been perfect, all the wires even connect better and come out easier on removal, all and all im very happy with my choice to spend the money again to get the higher end version.

    This Corsair RM1000x is wonderful. The individual cables that are not bulky have been everything I've wanted in a power supply. The cables are very fine and thinly profiled. Easy cable management. Worked perfect with my 5080. 10/10 recommend.

    Corsair makes great products and this is no slouch ! I purchase a 5070TI video card and my 750 power supply wouldn’t run it at all. I purchased this unit used provided cables and it fired right up. Runs all of the components of my system flawlessly. I’d highly recommend thi quality power supply.

    It powers things. I have nothing negative to say about it. There hasn't been any issues with this. I went with corsair to match the build. Rule of thumb, if it truly is Gold rating, it's just as good.

    This Corsair RM1000x power supply is a really good product and works great, just like the title says. The build quality feels excellent, and it offers fantastic value for the price. Installation was straightforward thanks to the fully modular cables, which helped keep things tidy. It powers my system reliably without any issues so far. Definitely recommended if you need a high-wattage, quality PSU.
