850 W ATX 3.0/3.1 power supply
The Rosewill CMG850 delivers up to 850 W through a single +12 V rail. It carries 80 PLUS Gold certification with up to 92 % efficiency. The fully modular design lets builders connect only the cables their system needs. It targets desktop builders who want a compact, high-efficiency unit for modern graphics cards and multi-drive configurations.
ATX 3.0 and 3.1 compatibility
This unit meets both ATX 3.0 and ATX 3.1 specifications for transient response and power-excursion handling. A single strong 12 V rail simplifies load balancing across high-end GPUs. The 140 mm length fits many smaller cases where longer units would not. Hold-up time is rated at 16 ms minimum and power-good signal at 1-100 ms.
Four PCIe connectors and nine SATA ports
Four 6+2-pin PCIe connectors support multi-GPU SLI or CrossFire setups. Nine SATA power connectors provide ample drive capacity for storage-heavy builds. Two 4+4-pin EPS connectors feed modern motherboards. The 120 mm FDB fan runs silently while the 100-240 V active PFC input handles global mains without a switch.

Pytania dotyczące tego produktu
What does the 850 W rating mean once the unit is installed in a PC?
The single 12 V rail can deliver the full 850 W to graphics cards and CPU, so high-end gaming builds draw their peak power without rail balancing limits.
What does ATX 3.0 / 3.1 compatibility cap in practice?
The platform supports the 12 VHPWR power-excursion and timing requirements defined by ATX 3.0 and 3.1, allowing modern GPUs to trigger transient spikes within the spec window.
What clearance does the 140 mm length need in a case?
The chassis must provide at least 140 mm of depth from the PSU mounting face to any drive cage or cable routing barrier for the unit to fit.
