850W ATX 3.1 Power Supply

The Super Flower Combat FG 850W is a fully modular ATX 3.1 power supply certified 80 PLUS Gold. It delivers 850 watts of continuous power with 87 percent efficiency at 20 percent load, 90 percent at 50 percent load and 87 percent at 100 percent load. A 120mm fluid dynamic bearing fan and 100 percent Japanese capacitors support reliable operation.

Who This Suits

Builders assembling a modern PCIe 5.0 graphics card will appreciate the native 12V-2x6 cable included in the box. The full modular ribbon cable design keeps cable routing clean in standard ATX cases. Active PFC with 100V to 240V auto-detection makes it suitable for worldwide mains voltages.

Headroom And Limits

The 850W rating comfortably handles a high-end GPU and CPU combination under sustained gaming loads. Efficiency peaks at 90 percent during typical 50 percent load scenarios, reducing waste heat. Systems demanding more than 850W peak power or requiring multiple 12V-2x6 connectors will exceed this unit's capacity.

Questions about this item

Does my case need to accept a standard ATX power supply for the SF-850C12FG to fit?

Yes, the unit follows the ATX 3.1 form factor, so any case designed for a regular ATX PSU will accommodate it.

Will the native 12V-2x6 cable work with an older graphics card that only has 8-pin PCIe sockets?

The supply includes two 8-pin to 16-pin native cables; plug the 8-pin ends into the card and the 16-pin connector into the PSU.

How can I confirm the fan is running in its low-noise mode after I power on the system?

The 120 mm fluid-dynamic-bearing fan spins at low speed under light load and ramps up only when the internal temperature rises.
