About This Product
The CoolMax CUL-850B is an 850W semi-modular ATX power supply. It provides sufficient power for high-end gaming systems with a single GPU or mid-range systems with dual GPUs. While it offers a high wattage, its unknown efficiency rating and lack of modularity beyond essential cables may be a consideration compared to fully modular, 80 Plus certified units in a similar wattage class.
Verdict
“Suitable for budget-conscious users needing high wattage for a single high-end GPU.”
