ASRock PG-850PSF 850W SFX power supply

Compact SFX power for high-output builds

The ASRock PG-850PSF is an 850 W SFX power supply built to the ATX 3.1 and PCIe 5.1 specifications. It fits Mini-ITX and Micro-ATX cases while delivering the headroom modern graphics cards and CPUs demand. Fully modular cables keep the interior tidy and airflow unobstructed.

Platinum efficiency with a quiet 92 mm FDB fan

80 PLUS Platinum and Cybenetics Platinum ratings mean very little energy is wasted as heat, so the 92 mm fluid-dynamic-bearing fan can run slowly under typical loads. The unit handles up to 235 % power excursion and meets Lambda A++ noise targets. Protections include OCP, SCP, OVP, UVP, OTP and OPP across the 100-240 V, 50/60 Hz input range.

Native 12V-2x6 cable with thermal monitoring

A single 12V-2x6 connector ships in dual-colour sleeving that shows when the plug is fully seated, and an onboard NTC sensor feeds temperature data back to the PSU for automatic protection. The +5 V Boost function holds the rail near 5.15 V to counter voltage drop. Four SATA connectors, four peripheral plugs, two EPS cables and two 6+2-pin PCIe cables complete the modular set.
