850 W ATX 3.1 power supply for mainstream builds

The Super Flower SF-850C12DB delivers 850 W of continuous power through a single +12 V rail and meets the ATX 3.1 and PCIe 5.1 specifications. It is suited for builders assembling a mid-range desktop that requires a dependable fixed-cable unit without modular connectors.

Sustained-load behaviour and protection

Efficiency reaches 82 % at 20 % load, 85 % at 50 % load and 82 % at full load under the 80 PLUS Bronze programme. Active PFC and full-range 100-240 V input keep output stable during extended sessions, while over-voltage and overload protection circuits guard connected components.

Fixed ribbon cables and compact length

All power leads are flat ribbon cables that bend easily for tidy routing inside cases with limited depth. The 140 mm housing fits most standard ATX chassis, and eight SATA power connectors support multiple drives. The non-modular design means every cable remains attached, so unused leads must be managed during assembly.

Questions sur cet article

How loud and hot does the 850 W SF-850C12DB get when running at full load all day?

The 80 PLUS Bronze rating means the unit runs at 82% efficiency at 20% load, 85% at 50% and 82% at 100%, so waste heat stays low even during extended high-load sessions.

What cables or connectors must my build already have to use this non-modular SF-850C12DB?

All cables are fixed, so you only need motherboard headers that accept the 20+4 pin main connector and up to eight SATA power plugs for drives.

Will the ATX 3.1 compliant SF-850C12DB work reliably with my older PCIe 3.0 graphics card?

Yes, the single +12 V rail design and ATX 3.1/3.0 compliance ensure stable power delivery to legacy GPUs while also being PCIe 5.1 ready.
