    Great when paired with a lower end Ryzen chip. The cables are lower quality but work well. They dont snap easily into the PSU so push hard and double check. For boards with 6 pin power connector, the 12 pin cable on this is designed to split in 2, which isnt apparent at first.

    It was in my all white build and it looks soo good and even from 2018 it still runs very well

    I received this product and it never works, and also the carton was opened before and it was missing many things.

    Been using it for 4 months now without issues. Its super quiet and youd never know it was there. The modular aspect really keeps the case looking clean by only using the plugs you need.

    I usually try my best NOT to gravitate towards corsair, but when my power supply in which I THOUGHT was great due to being from one of the BEST in the market pretty much DIED, I needed something ASAP.

    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.

    El artículo no me duro ni dos meses de uso aún teniendo un batery backup. Estoy muy decepcionado del tan poco rendimiento que tiene ese power suply.

    It arrived dead and would not power the computer.

    What? A white PSU in a black case? No, I painted the inside of the case white. The Corsair RMX 750 looks awesome inside and is super quiet!
