Product information

Description

ASRock PRO-850G is an 850 W ATX power supply designed for desktop PCs, delivering continuous power for gaming rigs and workstation builds. The unit supports universal AC input (100–240 V, 50/60 Hz), provides a 24-pin ATX motherboard connector and includes SATA cables with lengths of 450, 570 and 690 mm as well as a 60 cm motherboard cable. Efficiency is certified 80 PLUS Gold and the power supply uses active cooling with a 120 mm fan. The compact ATX form factor and black finish fit standard cases while native PCIe 12V-2x6 connectors with dual color design help ensure correct connection during installation.

Advantages

The PRO-850G combines a high nominal output of 850 W with 80 PLUS Gold efficiency to reduce energy losses and heat generation under load. A low-noise 120 mm fan provides active cooling while keeping acoustic levels low during typical operation. Native 12V-2x6 PCIe connectors with ASRock Classic Green indicators make it easier to verify secure plug-in of GPU power cables. The unit also includes multiple SATA cable lengths to accommodate different drive layouts and a full set of protections for stable and safe operation.

Suitable for (tasks / use cases)

  • Gaming desktop systems with mid to high power graphics cards
  • Workstation builds requiring stable 850 W power delivery
  • Systems that benefit from 80 PLUS Gold efficiency to lower operating costs
  • PC builds where clear cable connection indication simplifies assembly

How to use

Mount the ASRock PRO-850G into a compatible ATX power supply bay inside the PC case and secure it with the provided screws.
