The Corsair RM850x 2024 is a high-performance 850W ATX 3.1 power supply designed for demanding desktop builds. With its sleek black finish and fully modular cabling, it offers a clean and flexible installation experience. The unit delivers up to 849.6W on the +12V rail and operates at up to 90% efficiency, earning it an 80 PLUS Gold certification. Its compact ATX form factor, measuring 160mm in depth, makes it compatible with a wide range of cases.
Semi-Passive Cooling and Quiet Operation
The RM850x 2024 features a semi-passive cooling mode, allowing the single 140mm fan to remain completely off under low to moderate loads. This results in near-silent operation during everyday tasks and lighter workloads. When the system demands more power, the fan automatically spins up to maintain safe operating temperatures. This approach balances thermal management with acoustic comfort effectively.
Connectivity and Protection
Designed with modern systems in mind, the RM850x 2024 includes two 4+4 pin CPU connectors, three 6+2 pin PCIe connectors, eight SATA power connectors, and three Molex connectors, providing ample connectivity for complex builds. The fully modular design ensures only the cables you need are connected, reducing clutter inside the case. Built-in power protection features help safeguard connected components against potential electrical irregularities. The ATX 3.1 and EPS 2.92 compliance ensures broad compatibility with the latest motherboards and processors.
