850 W ATX 3.1 power supply

The Super Flower SF-850F14XP delivers 850 W through a fully modular ATX 3.1 design. It is built for systems that need PCIe 5.1 readiness and stable output under heavy load. The single +12 V rail simplifies power distribution for high-end components.

Native 12VHPWR cables and ribbon layout

Two native 12VHPWR cables remove the need for adapters when connecting modern graphics cards. All cables use a ribbon layout that eases routing inside tight cases. Full modularity means only the required leads stay in the chassis.

Platinum efficiency at 115 V and 230 V

80 PLUS Platinum and Cybenetics Platinum ratings confirm 90 % efficiency at 20 % load, 92 % at 50 % load and 89 % at full load on 115 V input. On 230 V input the overall efficiency reaches 91 % to 93 %. The 140 mm fluid-dynamic-bearing fan and 105 °C Japanese capacitors keep thermals controlled up to the 850 W limit.

Questions about this item

Will the native 12VHPWR cable fit my PCIe 5.1 graphics card without an adapter?

Yes, the unit ships with two native 12VHPWR cables that plug directly into a PCIe 5.1 graphics card, so no adapter is required.

Can this 150 mm deep unit fit in a compact case that only accepts shorter power supplies?

The power supply is 150 mm long; measure the available depth in your case from the mounting face to the nearest obstruction to confirm clearance.

What efficiency can I expect at typical loads on a 230 V mains supply?

Cybenetics Platinum certification shows 91 % to below 93 % overall efficiency at 230 V input across the load range.
