    The first one was originally doa. The second one i got through warranty worked like a charm. Use that info for what you will.

    went downhill after a few months. pc started giving me Kernel Power 41 Errors after a few months using it and I thought it was just a driver issue or other hardware issues. I did try to fix everything correctly and thoroughly. spent amounts of time trying to get rid of this error but no luck. pc turns off randomly and eventually it just stops powering on. i spent extra money on another PSU from NewEgg which is a MSI PSU just to test it out. turns out the culprit was this Corsair RMx. sorry to say but im never buying a PSU from amazon again because at the end of the day. this just seems like a rip off.

    Fully modular psu with bunch of different cable for every modern setup. Works good, had no issues whatsoever

    Zero RPM fan mode: at low and medium loads The cooling fan switches off entirely for near-silent operation

    After 5 months of normal usage, my system starts to randomly shut down and then no boot at all. Replaced with another lower powered and lower-rated PSU, it came back again. Amazon gave me a full refund.

    I like the look and wires of the connectors provided. When power consumption is low, the power supply unit is almost undetectable. But when you do start to crank up power, this unit gets real loud. I wear ear cupped headphones and can still hear it loud and clear. I’m unsure if I have a faulty unit or if that’s just the way it is, but it gets really loud. I’ve owned Corsair power supplies before, and have never experienced this type of noise from a power supply.

    I just installed this new psu and it’s great and quiet!

    The first thing that sets this power supply apart from others is the heavyweight metal housing, and the tough black powder coating. OEM and budget power supplies come housed in flimsy metal, so CORSAIR has an immediate advantage in the visual and tactile quality test. Looks and feel arent everything, but theyre a good start. Also, by personal choice, I am a big fan of the clean black appearance with only white for labeling, and the all-black cables included. It really adds to the look of a finished build; gone are the rainbow cables from the past.

    Spent the past 2 months building a computer. As parts are hard to find these days, it took me a while to get everything together. My system is as follows - 850W Corsair White series, 16GB Corsair Vengeance RAM, 10700K and 2 WD m.2 drives. I also have 2070 GTX but did not install it in the system. I was able to post BIOS than I shutdown the PC. I attempted to restart it to install WIN 10 and nothing happened. I tried testing the Corsair RMX White Series and the fan spun but no peripherals (2 fans and an old hard drive) worked. Of course, I am just past the 30 day deadline to return my purchase to Amazon. Always test your hardware as you receive it. Lesson learned. I now have a very expensive paperweight. And its impossible to purchase a replacement. The PSU looks good though. Nice cables.
