About This Product
The Corsair RM850x is an 850W 80+ Gold certified fully modular ATX power supply. It provides sufficient power for high-end single-GPU systems, including those with an RTX 4070 or RX 7800 XT, and offers good efficiency for reduced heat and power consumption. While reliable, its 180mm length is longer than some ATX PSUs, which may be a consideration for smaller cases.
Verdict
“A reliable 850W PSU for high-end gaming PCs requiring 80+ Gold efficiency.”
