Thermalright KG-650 650W Gold Fully Modular ATX 3.1 PSU
The Thermalright KG-650 650W Gold Fully Modular ATX 3.1 PSU is a 650 W, 80 PLUS Gold ATX 3.1 power supply. It has fully modular cables, a 120 mm fan and OPP/OVP/OTP/OCP/SCP/UVP protections.
It suits mainstream gaming and work PCs that need a steady 650 W supply. Because it is fully modular, you only connect the cables you use, which keeps the case tidier and improves airflow. It is a good fit for new builds or for replacing an older, less efficient unit. Browse more power supplies if you need a different wattage.
