## Long description

ASRock Pro Series PRO-850B 850W ATX 80+ Bronze is a desktop power supply designed to deliver continuous, stable power for standard ATX systems. With an 850W output and 80+ Bronze efficiency, it supports gaming PCs, content-creation workstations and system upgrades that require higher sustained power. The unit comes in a black enclosure that fits most mid-tower and full-tower cases and includes the common power connectors needed for mainstream motherboards, graphics cards and storage devices.
Advantages
The power supply combines an 850W continuous output with 80+ Bronze efficiency to reduce wasted energy and heat under typical loads. Built for desktop use, it provides multiple protection features to maintain stable voltage and guard components. The black housing and standard ATX form factor ensure compatibility with a wide range of PC cases and system builds. Cable layout and connector selection are chosen to support modern systems while keeping installation straightforward.
Suitable for
Gaming PCs requiring reliable high-wattage supply for graphics cards and CPUs
Workstations for video editing, 3D rendering or multitasking workloads
System upgrades where existing power capacity is insufficient
Standard ATX desktops where compatibility and steady power delivery are priorities
Key specifications
Output power: 850 watts continuous
Efficiency certification: 80+ Bronze
Form factor: ATX desktop PSU
Color: black enclosure
Protections: over-voltage, under-voltage, over-current and short-circuit protection (implementation varies by model)
Cooling: internal fan for thermal management
Connector types: standard motherboard 24-pin, CPU 4/8-pin, multiple PCIe and SATA power connectors (exact counts depend on unit)
How to use
Install the power supply into a compatible ATX case, securing it with the supplied screws and aligning the fan and cable routing to the case layout. Connect the 24-pin motherboard connector and the CPU 4/8-pin power connector first, then attach PCIe power connectors to graphics cards and SATA/Molex connectors to storage and peripherals as required. Ensure all connections are fully seated before powering the system. Use appropriate cable management to maintain airflow and prevent cables from obstructing fans or components.
Usage recommendations
For reliable operation, operate the power supply within its rated output capacity and provide adequate case ventilation. When building or upgrading systems with high-power graphics cards or multiple drives, verify total system power draw and allow headroom of 15–25% above estimated peak consumption. Use quality surge protection or an uninterruptible power supply (UPS) for added protection against mains instability.
