    Can’t hear or smell it, works and looks great. For over 2 decades I only trust Corsair. Pushes my Ryzen 3700x and 1080ti VR rig with ease.

    It isnt the best, its just a good, solid PSU that should give you many years of trouble free operation. I have had no issues with it in my new 10850k build, even though I am not utilizing the full power of this product, but I will get closer to it when I drop a new 3080 card in the system later this year. My 1080Ti runs here for now.

    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.

    I received the wrong versión of this product, I was expecting to receive the RM850x which is an updated version and better quality components including the fan, but I got the RM850 instead which is $100 cheaper.
