## Summary description

ASRock PRO-850G is an ATX power supply unit delivering 850 W total power with 24-pin motherboard connector and 80 PLUS Gold efficiency. It supports 100–240 V AC, active cooling via a 120 mm fan and multiple SATA power cables. Designed for desktop PCs requiring reliable high-power delivery and efficient operation.

## Long description

ASRock PRO-850G is an ATX power supply unit that provides 850 W of continuous power with a 24-pin motherboard connector and 80 PLUS Gold efficiency. Designed for desktop PCs, it supports 100–240 V AC input at 50/60 Hz and includes active cooling via a 120 mm fan. The unit comes in black and offers multiple SATA power cable lengths to accommodate modern system builds while aiming for efficient power delivery and reduced energy waste.
Advantages
The PRO-850G delivers a high continuous output of 850 W with an 80 PLUS Gold efficiency rating, which helps reduce electricity consumption and heat generation compared with lower-efficiency units. Native 12V 2x6 PCIe connectors and a full-size 24-pin ATX motherboard connector simplify installation for contemporary components. A low-noise 120 mm fan and an ATX form factor make it suitable for most mid-tower and full-tower cases. The black finish and ASRock dual-color connector design aid correct cable seating during build and maintenance.
Suitable for
High-performance gaming PCs with discrete graphics cards requiring stable 12 V rail delivery
Workstations for content creation, video editing, or 3D rendering that need sustained power
System builders assembling ATX desktop PCs that prioritize efficiency (80 PLUS Gold)
Upgrading existing desktops that require an 850 W PSU with multiple SATA connectors
When it may not be suitable
This power supply may be excessive for very small, low-power office or home PCs that consume well under 400 W; in such cases a lower-wattage, more compact unit could be more cost-effective. It is a standard ATX form factor unit and therefore not suited for proprietary or slim/compact case designs that require SFX or other non-ATX power supplies.

How to use
Install the ASRock PRO-850G into a compatible ATX case, securing it to the chassis using the standard screw positions. Connect the 24‑pin ATX cable to the motherboard and route PCIe 12V 2x6 connectors to graphics cards as required. Use the provided SATA power cables for storage devices, choosing the appropriate cable length for tidy cable management. Ensure AC mains are within the supported 100–240 V range and connect the PSU to a properly grounded outlet. Power on the system and verify stable boot and voltage delivery; consult the motherboard and component manuals for any additional power configuration steps.
What to consider before purchase
Check your system’s total power draw to confirm 850 W is appropriate for your CPU, GPU(s) and peripherals
Verify your PC case supports ATX form factor dimensions and mounting points
Confirm required connector types and lengths (24-pin ATX, PCIe 12V connectors, SATA lengths)
Consider efficiency needs and whether 80 PLUS Gold meets your energy and noise priorities
Usage recommendations
For reliable operation, allow adequate airflow in the case, avoid obstructing the 120 mm fan, and route cables to minimize heat buildup. When installing high-power GPUs, connect each graphics card using the native PCIe 12V 2x6 connectors provided, and ensure the PSU is connected to a stable mains supply within the specified voltage range.
