AI Verdict
This 850W 80 Plus Gold fully modular ATX power supply with a 140mm fan is for PC builders needing standard power delivery with a 10-year warranty.
This 850W 80 Plus Gold fully modular power supply offers standard features like a 10-year warranty and a compact 140mm depth. However, conflicting user reports on noise and reliability, particularly concerning the '2024' version, suggest inconsistent performance.
If consistent quiet operation and proven long-term reliability are critical, look for power supplies with more consistent user feedback on fan noise and internal component quality, potentially from a different OEM.

Pros
- Provides 850W of power with 80 Plus Gold efficiency, saving energy up to 90%.
- Features a fully modular design, allowing for better cable management and only connecting necessary cables.
- Includes a 10-year warranty, indicating manufacturer confidence in longevity.
- Designed with a compact 140mm depth, providing more space for cable routing within a PC case.
- Equipped with industrial-grade protections including OCP, OVP, UVP, OPP, SCP, and OTP to safeguard components.
- The Smart Zero Fan feature is intended to minimize noise by stopping the 140mm fluid bearing fan at low loads.
Cons
- Some users report the fan running constantly and being noisy, idling at 40dB, contradicting the 'Ultra Quiet' and 'Zero RPM' claims.
- Flat cables are reported to be stiff and difficult to bend, complicating cable routing in tight spaces.
- Multiple user reports indicate units failing after moderate use, some within 7 months, with issues like sudden shutdowns or burning plastic smells.
- There are user concerns that the '2024' version (which this model is) may use lower quality internal components compared to older GF1 iterations.
Dimension Scores
The unit is 80 Plus Gold certified, achieving up to 90% efficiency, and provides 850W output with a high amperage single +12V rail.
Despite the 'Smart Zero Fan' and 'Ultra Quiet' claims, some users report the 140mm fan running constantly and idling at 40dB, contradicting silent operation.
It includes industrial-grade protections and a 10-year warranty, but user reports of units failing after 7 months and concerns about 'cost down' components suggest inconsistent internal quality.
The fully modular design aids in cable management, but the stiffness of the flat cables makes them difficult to bend and route effectively.
Best For
- Mid-range to high-end gaming PC builds requiring 850W of power.
- Users prioritizing a fully modular design for a clean internal build.
- PC builders who value a long manufacturer warranty for component peace of mind.
- Systems where a compact 140mm deep power supply is beneficial for case compatibility.
Not Recommended For
- Silence-focused builds where consistent fan noise, even at low loads, would be an issue.
- Users who need highly flexible cables for intricate cable management or small form factor cases.
- Budget-conscious builders looking for the absolute lowest price point, given reported reliability concerns.
Watch Out For
- The 'Smart Zero Fan' feature doesn't always work as advertised; some users report the 140mm fan running constantly and producing 40dB of noise even at idle.
- Units have reportedly failed after 7 months of moderate use, with some experiencing sudden shutdowns and mechanical noises.
- Users have detected a burning plastic smell and issues with power output stability, indicating potential internal component failure.
- The flat, fully modular cables are stiff, making them difficult to route and bend, especially against the wide grain.

What Buyers Say
The most surprising finding is the significant discrepancy in user experiences regarding noise, with some reporting it 'ultra quiet' while others measure 40dB at idle, directly contradicting the 'Zero RPM' feature. There's also a recurring concern about the '2024' version potentially using lower quality components, leading to reports of units failing after several months of use, sometimes with burning smells or sudden shutdowns. The stiff, flat cables are a consistent complaint, making routing challenging for many builders. Despite these issues, some users have had flawless experiences for months.
“Man, I thought 'Zero RPM' meant ZERO NOISE, but this fan just keeps spinning and it's louder than my old PSU! And after only a few months, it just died on me, smelled like burnt plastic, seriously annoying.”
Common Praise
- The fully modular design simplifies connecting only necessary cables.
- The 10-year warranty provides a long period of coverage.
- The 80 Plus Gold efficiency rating helps reduce power consumption.
- The compact 140mm depth fits well in various PC cases.
- Includes comprehensive industrial-grade protections for hardware safety.
Common Complaints
- The 140mm fan can be noisy and run constantly, even when the 'Smart Zero Fan' feature should keep it off.
- Units have failed within 7 months of moderate use, exhibiting mechanical noises or sudden power loss.
- A burning plastic smell was reported by users, indicating power output stability issues.
- The flat power cables are stiff and difficult to bend, complicating cable routing.
- Concerns exist that the '2024' model might be a 'cost down' version with inferior parts.
Ownership Tips
- The 'Zero RPM' fan feature might not always engage, leading to constant fan noise even at low system loads.
- Cable stiffness can make achieving a clean build difficult, requiring more effort to route and hide cables.
- Some users have experienced unexpected failures, suggesting a need for a backup plan or careful monitoring, especially with the '2024' version.
- The compact 140mm depth is genuinely helpful for smaller cases or those with limited PSU shroud space.
Frequently Asked Questions

Buying Guide
When you're looking at a power supply, you're essentially buying the heart of your PC. It needs to reliably deliver power to all your components without failing or making too much noise. You need to match the wattage to your system's needs, and consider the efficiency rating for how much power it wastes as heat. Modularity helps keep your case tidy, but cable quality also matters for ease of installation.
