ATX 3.1 & PCIe 5.1 Next-Gen ReadinessStay well ahead of modern hardware requirements without constraint. The SL-850GW strictly complies with the advanced ATX 3.1 and PCIe 5.1 electrical standards, engineered precisely to absorb intense microsecond transient power excursions up to 200% of its rated capacity. Massive power spikes from top-tier graphics accelerators are handled cleanly, actively preventing unexpected system freezes, protective blackouts, or hard reboots.

Dual Color Design
With ASRock Classic Green connectors, users can easily see if the connector has been plugged properly.

iCOOL Intelligent Fan Control Mode
iCOOL Mode ON: The power supply runs more efficiently. The fan stays off during low to medium loads, reducing noise and improving energy efficiency. The fan only activates when the load or temperature increases.
iCOOL Mode OFF: The fan runs continuously, regardless of load. This may increase noise slightly but provides consistent cooling and better performance under heavy loads.
