Power essentials at a glance

Clean, efficient 80 PLUS Gold performance

This unit is 80 PLUS Gold certified, which means it wastes less energy as heat. Less heat reduces internal temperatures and helps your fans run quietly. Because the design targets value-focused users, you get solid efficiency without unnecessary extras. In practice, your system stays efficient during long gaming or rendering sessions.

ATX 3.1 compatibility with modern GPUs

The Asrock PRO-850G supports ATX 3.1 and includes a native PCIe 12V-2×6 cable. This helps deliver stable power to newer graphics cards that use the 12+4 pin connector. So you can build with confidence, knowing the PSU can handle transient loads. We also supply standard 6+2 pin connectors for legacy cards.

Easy-build connectors and clear signalling

We fit Dual Color Design connectors across the range, using ASRock Classic Green to show a secure fit. The 24-pin ATX motherboard cable is 60 cm for tidy routing in most cases. You also get multiple SATA and peripheral connectors for drives and accessories. This makes cable management straightforward in both compact and full towers.

Comprehensive protection suite

We include full power protection features to guard your components. Over current, over voltage, under voltage, short circuit, over power, and overheating circuits are built in. Because the PSU monitors conditions continuously, your system is shielded during normal and extreme loads. This helps prevent damage from unexpected spikes or faults.

Quiet, focused cooling

A single 12 cm fan provides active cooling that balances airflow and noise. The design prioritises stable operation over flashy lighting, with no illumination. So your case stays uncluttered, and the PSU runs quietly under typical workloads. This makes it ideal for builds where acoustic comfort matters.

Build checklist before you order

• Confirm your case supports standard ATX PSUs with 150 mm width and 140 mm depth.
• Check that your motherboard has a 24-pin ATX and 4+4 pin EPS connector.
• Verify your graphics card requires 6+2 pin or 12V-2×6 power.
• Ensure you have space for the 86 mm height and typical cable bends.
