  • Great PSU
Style: RMe (2025) Size: 850 Watts Color: White
Love this power supply got it some time ago and it's been working with no problem and great cable quality too, and the zero-fan mode is very noise to keep things quiet when no doing heavy games or apps, and its size really makes it a versatile PSU and easy to install compared to others in my opinion. great power supply!! ... show more

  • Another excellent PSU from Corsair
Style: RMe (2025) Size: 850 Watts Color: White
I love Corsair, and this is yet another in a long line of great PSUs I've bought from them. There's not a lot to say about this power supply. It works well. It supplies power to your PC. The cable stiffness is good. It was easy to install in my Corsair 3500X case. It's an all around great PSU and you get bang for your buck with it. ... show more

Eh, never really used it and mainly purchased for replacing another psu but never got to that point but I did notice a capacitor smell coming from it when not plugged in...was pretty strong so idk if something could have been wrong with it but usually when you smell that it means there's a capacitor leak. ... show more

  • Great Power Supply!
Style: RMe (2025) Size: 850 Watts Color: Black
This power supply works great so far! The modular design, flexible cables and updated GPU power connection makes this a no brainer for those loooking to upgrade. Only time will tell when it comes to durability, but if this PSU has the build quality of my last Corsair PSU, I'm sure I wont be dissapointed. ... show more
