Purpose and Audience

The ASRock SL-850P is an 850 W ATX 3.1 power supply built for modern desktop builds. It targets system integrators and enthusiasts who need reliable, efficient power delivery for high-performance components.

Critical Specification

The unit provides a native PCIe 5.1 12V-2x6 connector with dual-colour cables and an integrated NTC sensor for temperature monitoring. This single connector decides compatibility with current-generation graphics cards that require the 12V-2x6 interface.

Thermals Noise and Power

A 135 mm striped axial FDB fan operates under iCool intelligent control. In iCool mode the fan remains off at low to medium loads for silent running and spins up only when load or temperature rises. The 80 PLUS Platinum and Cybenetics Platinum ratings confirm high efficiency across the load range.

Questions about this item

Will the single 12V-2x6 connector support a graphics card that needs two 12VHPWR inputs?

The unit provides one native 12V-2x6 cable; a card requiring two such connectors would need an adapter or a different PSU.

Does the 135 mm FDB fan stay off at idle when iCOOL mode is enabled?

Yes, iCOOL ON keeps the fan stopped during low to medium loads and spins it up only when load or temperature rises.

Are all cables fully modular so I can remove the unused peripheral leads?

The PSU uses a fully modular design, letting you connect only the 24-pin, EPS, PCIe and peripheral cables your build requires.
