### ⭐⭐⭐⭐⭐ Excellent PSU
*by J***C on December 6, 2025*

Clean, efficient, and easy to use. Running my 10850k, 4070, and all the other crap shoved in my tower with zero issues. Modularity is excellent for keeping your system from being a spaghetti mess by only using the cables you need. Included molex cable is excellent if your still using some older hardware or fan hubs. You get what you pay for and corsair is worth the cost to keep your system running stable.
