    Very worth the money in my opinion needed a good power supply for my overclocked 5080. this thing came in clutch because it already had 4 pcie cables, so it was 50 series ready out the box. also super simple to put together.

    Not much to say, high quality single purpose piece of hardware. Powers my 7900xtx over locked beautifully. My previous 800watt couldn’t keep up with transient spikes, this solved the issue. It may be as powerful as a microwave, but it works well. Came with plenty of accessory cabling and I like the look of the individually textured cables.

    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!!!!

    Convenient way to wire your gaming PC. The modular design and fan speed control help make this a capable PSU for even the most demanding RTX 50-series GPUs. While this may not have enough power for extreme thread riper CPUs, it handles my i9 with RTX 5080.

    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.
