A Fully Modular Cabling System

All cables detach from the power supply. During installation, this gives you the flexibility of using only the cables you need for a clean system build with optimal airflow. And, when it's time to replace or upgrade your power supply, it can be removed from your system without interfering with your cabling — the cables stay in place and connect to your new fully-modular Corsair power supply.

Jonny Guru Recommends the AX750

" The Corsair AX750 shows that it is capable of producing the performance users want at a moderate price point. Although we did note that we seen out of spec ripple on the +5VSB in our second crossload test, one must remember that it's very unlikely to see that heavy of a crossload situation in the real world. How could you really go wrong with a unit such as the AX750? It puts out the power offering the user 80 Plus Gold efficiency even though I took the unit almost 10° past its 50°C rating."
