Running my 14700K and 4080 Super without issues. The fan is virtually silent. Fully modular made cable management a breeze. ATX 3.1 is ready for future. Great PSU.
Works well, no coil whine. The cables are flexible and the connectors are sturdy. Just a bit expensive, but you get what you pay for.
Upgraded from an old unit and the difference is night and day. The 12V-2x6 cable is a bonus. The unit runs cool and quiet. Highly recommend.
I completed a new build with a 4070 Ti Super and this PSU. It's quiet, efficient, and fully modular. The ATX 3.1 certification is reassuring. Very satisfied.
The PSU works great, but I wish the warranty were longer. It's been running smoothly for a month now. No complaints otherwise.
My PC is whisper quiet now. The power supply doesn't even spin the fan most of the time. The modular cables are easy to manage. Worth it.
It's a solid unit, but I noticed a faint noise under heavy load. Not as quiet as advertised. However, it performs well.
No issues after several months. It powers my overclocked system with ease. The sleeved cables look good. This is my third Corsair PSU and they never disappoint.
Works perfectly. No noise at all.
Mine arrived dead. Had to return it. Probably a defective unit, but not a good first impression.
I bought this for a friend's build and it works fine. The cables are a bit stiff, but that's typical. The performance is solid and the price is reasonable.
