Why this product
80 PLUS Gold efficiency
Delivers 850W of stable power while minimizing wasted energy as heat. Reduces electricity costs over the life of your system.
ATX 3.1 and PCIe 5.1 ready
Native 12V-2x6 connector supports next-generation graphics cards and power-hungry components without adapters.
Non-modular design
All cables are permanently attached for maximum reliability and lower cost, though cable management requires more planning.

Best for
- Mid-to-high-end gaming builds
- Workstations and content creation rigs needing stable 850W delivery
- Builders prioritizing reliability and warranty over cable flexibility
- Systems with current-generation and next-gen graphics cards
- Budget-conscious upgraders seeking Gold efficiency without modular cost
Trade-offs
- Enthusiast cable management. Non-modular design means every cable is permanently attached, making clean custom loops or heavily planned routing harder.
- Ultra-compact builds. At 140 × 150 × 86 mm, it requires adequate space in smaller form-factor cases.
- Future-proofing beyond 850W. Maximum output is capped at 850W; systems expecting to exceed that load need a larger unit.
With ASRock Classic Green connectors, users can easily see if the connector has been plugged properly.
The PRO series is created for value-focused users, offering 80 PLUS Gold models in 850W, 750W, and 650W options.
Full suite of protections to keep all components safe during normal to extreme power levels.
ASRock offers an outstanding 3-Year warranty, guaranteeing long term reliable and peace of mind operation.
