AI Verdict
This 850W ATX3.1, PCIe5.1, 80 Plus Gold, Cybenetics Platinum fully modular PSU with Japanese capacitors is for builders prioritizing future-proofing and quiet operation, but be aware of reported relia
This PSU is a situational fit because it offers cutting-edge ATX3.1 and PCIe5.1 compatibility with a native 12V-2x6 connector, 850W, and high efficiency, which is great for modern systems. However, recurring user complaints about random shutdowns and coil whine introduce a significant risk that makes it less of a strong, universal recommendation.
If reliability concerns outweigh the feature set, look for a PSU with a proven track record of stable operation and minimal noise complaints, even if it means sacrificing some of the latest ATX standards or paying a bit more.

What Buyers Say
What's wild is how many people are reporting random shutdowns and coil whine, even with this being an A-Rated PSU on some tier lists. It seems like ASRock pushed for all the right certifications and features, like the ATX3.1 and PCIe5.1 readiness, but some units are just acting up, which is a bummer when you're trying to power a high-end rig. The braided cables are a definite win for aesthetics, though.
“Man, I really wanted to like this thing with the braided cables and the ATX3.1 stuff, but it just kept randomly shutting down my PC, and the coil whine was driving me nuts. Had to send it back, so annoying!”
Common Praise
- The individual braided cables look really clean in a build.
- It's fully modular, making cable routing much less of a headache.
- The 10-year warranty gives a lot of confidence in the purchase.
- The PSU is quiet when the fan is operating normally.
- It's ready for ATX3.1 and PCIe5.1, so it feels future-proof.
Common Complaints
- My system randomly overheated and shut off, had to return it.
- There's a noticeable 'massive coil whine' coming from the unit.
- Heard a 'zumbido' (humming/buzzing) even after unplugging it, and it shut down randomly.
- Received a unit that was 'DOA' and the power cord looked like it had been used.
Ownership Tips
- Some users found that the 'dual color design' on the 12V-2x6 cable is a subtle aesthetic touch that blends well with most builds.
- The 'TempGuard' technology on the 12V-2x6 connector isn't something you actively notice, but it's there for peace of mind during heavy GPU loads.
- The fan control seems to keep it silent under light to medium loads, but the coil whine can kick in under specific conditions, not just heavy load.
- The fully modular design really does make a difference when you're trying to keep your case tidy, especially with the individually sleeved cables.
Frequently Asked Questions
Does this PSU come with all the cables I need for a modern PC build?
Yes, it's fully modular and includes a native 12V-2x6 cable, which is essential for many current high-end GPUs, alongside standard ATX and PCI Express connectors.
Is this power supply quiet during operation?
It features a 135mm Fluid Dynamic Bearing fan and iCool Intelligent Fan Control, designed for quiet operation. However, some users have reported 'massive coil whine' or a 'zumbido' (humming/buzzing).
What does 'ATX3.1 & PCIe5.1 Ready' mean for me?
This means the power supply is compliant with the latest power standards, ensuring it can handle the power demands and transient loads of next-generation GPUs and CPUs, making it suitable for future upgrades.
What kind of warranty does this PSU have?
ASRock provides a 10-year warranty for this power supply, which is a substantial period and offers long-term assurance for your purchase.
Are the cables individually braided?
Yes, the product title specifies 'Individual Braided Pattern', which typically means each wire within a cable is sleeved, offering a cleaner look and easier routing.
Buying Guide
When you're looking at a power supply, you're basically picking the heart of your PC. You need enough wattage to power all your components, especially your graphics card. Efficiency ratings like 80 PLUS Gold tell you how much power it wastes as heat – higher efficiency means less wasted energy and potentially less heat in your case. Modular cables are a game-changer for keeping your build clean, letting you only plug in what you need.
Wattage (850W)
This is the total power your PSU can deliver. Think of it like the horsepower of a car; you need enough to get your system running smoothly, especially if you have a powerful graphics card and CPU. 850W is plenty for most high-end single-GPU gaming PCs.
80 PLUS Gold & Cybenetics Platinum
These are efficiency ratings. 80 PLUS Gold means it's at least 87-90% efficient, while Cybenetics Platinum is an even stricter standard, meaning less electricity is wasted as heat. This saves you a tiny bit on your power bill and keeps your PC cooler.
ATX3.1 & PCIe5.1 Ready with 12V-2x6 Connector
This is about future compatibility. Modern graphics cards (like NVIDIA's RTX 40-series) use a new 12V-2x6 power connector. ATX3.1 is the latest standard for PSUs, ensuring they can handle the massive, sudden power spikes these new GPUs can draw without shutting down your system. Having this means you're ready for the newest hardware.
Fully Modular
This refers to the cables. A fully modular PSU lets you detach every single cable that isn't hardwired. This is a huge win for cable management, as you only plug in the cables you actually need, reducing clutter and improving airflow inside your PC case.
Alternatives
If this PSU's reported reliability issues are a concern, look for an 850W ATX3.1, PCIe5.1 fully modular power supply from a brand with a strong reputation for consistent quality control and minimal user complaints regarding coil whine or random shutdowns.
