ASUS Prime 850W Gold PSU - ATX 3.1, PCIe 5.1, 80+ Gold
The ASUS Prime 850W Gold PSU is a 850W ATX 3.1 power supply built for high-performance workstations, all-round PCs, and gaming rigs that need efficient, long-lasting power delivery. It carries 80 Plus Gold certification, ships with a 16-pin PCIe 5.1-compatible cable for next-generation graphics cards, and backs the whole package with an 8-year warranty.
Why this product
80 Plus Gold: up to 92% efficiency
Low-ESR capacitors earn it 80 Plus Gold certification, delivering up to 92% efficiency — which means less heat generated and reduced fan noise during operation.
Dual ball bearings rated to 80,000 hours
The fan uses dual ball bearings with a rated lifespan of 80,000 hours — twice as long as sleeve bearing designs and longer than fluid dynamic bearings — keeping cooling reliable and quiet over the long term.
ATX 3.1 and PCIe 5.1 ready
Fully compliant with ATX 3.1 voltage and current regulation guidelines, and bundled with a 16-pin PCIe cable compatible with PCIe Gen 5.1 graphics cards.
8-year warranty
An 8-year warranty is included, covering defects across a longer period than many competing units in this class.
Two-tone housing fits either build theme
Two sides of the housing are painted white and two are painted black, so you can orient it to match a light or dark build without buying a separate variant.

- EAN4711387192658
- Compatible with ATX 3.1 motherboards and cases that accept a standard ATX form factor (150 × 150 × 86 mm).
- Bundles a 16-pin PCIe cable compatible with PCIe Gen 5.1 graphics cards.
- Accepts a wide AC input range of 100–240 V, making it suitable for use in most regions.
- Includes CPU 4+4-pin connectors ×2, covering boards that require two EPS connectors for high-core-count CPUs.
- 0dB fan-stop technology is not included — the fan runs continuously rather than stopping under light load.
- AURA SYNC RGB lighting is not supported; there is no addressable lighting on this unit.
Best for
- Gaming PC builders who need a PCIe 5.1-ready supply for a current or upcoming high-end graphics card without paying for a fully modular unit.
- Long-term builders who value the 8-year warranty and 80,000-hour fan bearing rating over a shorter-warranty alternative.
- Efficiency-conscious users who want up to 92% efficiency at load to reduce heat output and running costs.
- Mixed-theme builds where the two-tone black-and-white housing can be oriented to suit either a dark or light case interior.
Trade-offs
- Silent-running builds: the fan runs at all times — 0dB technology is explicitly not included — so this unit is not suited to builds where fan-stop under light load is a requirement.
- RGB-focused systems: AURA SYNC and addressable lighting are explicitly absent, so buyers wanting a lit PSU to match an RGB build will need a different model.
- Very high-wattage workstations: total output is 850W; systems with a combined load that exceeds this will require a higher-wattage unit.
- Cable-management-focused builds: this is not a modular or semi-modular design, so all cables are permanently attached and unused ones must be managed inside the case.
ASUS Prime 850W Gold PSU brings efficient and durable power delivery to all-round PCs, and gaming rigs. Dual ball fan bearings that can last up to twice as long as sleeve bearing designs.
Prime Performance
With 80+ Gold certification, dual ball fan bearings, and an 8-year warranty, the ASUS Prime series PSU brings efficient and durable power delivery to high-performance workstations, all-round PCs, and gaming rigs.
Dual Ball Fan Bearings
Dual ball bearings boast a remarkable lifespan of 80,000 hours, lasting twice as long as sleeve bearings and exceeding even fluid dynamic bearings. Ensuring long-lasting, reliable cooling with minimal noise for ASUS Prime Gold series.
80 Plus Gold Certification
The ASUS Prime 850W Gold PSU features efficient, low-ESR capacitors to ensure efficient operation — affording it 80 PLUS® Gold status. This means it delivers up to 92% efficiency, resulting in less heat, reduced fan noise, and increased reliability.
ATX 3.1 Compatible
The latest power specification updates have landed. ATX 3.1 ushers in tighter voltage and current regulation guidelines for next-gen hardware - and ASUS Prime 850W Gold steps ahead of the curve by being fully compliant. A 16-pin PCIe cable that is compatible with PCIe Gen 5.1 graphics cards is bundled with the PSU, bringing large-scale capabilities.
Choose Your Style
Two sides of the housing are painted white, and two sides are painted black, allowing you to orient the PSU to match your preferred build theme.
