Dimension Scores
The unit is 80 Plus Gold and Cybenetics Platinum certified, but narrowly missed 80 Plus Platinum at full load.
It operates silently at low to medium loads due to iCool fan control, but the 135mm fan can get noisy under heavy stress.
It incorporates 100% Japanese capacitors and comes with a 10-year warranty, indicating a focus on durability.
The fully modular design with flexible, flat cables and a dual-color 12V-2x6 connector offers excellent cable routing options.
Best For
- High-end gaming PCs with power-hungry GPUs requiring PCIe 5.1 power connectors.
- Future-proof PC builds anticipating next-generation components and power standards.
- Systems where quiet operation is desired during light to moderate workloads due to its iCool fan mode.
- Users who prefer a clean build with customized cable routing, thanks to its fully modular design.
Not Recommended For
- Budget-constrained builds where a 1000W, Platinum-rated PSU might be overkill.
- Users who consistently push their systems to maximum load and prioritize absolute silence under all conditions.
- Small form factor (SFF) builds, as it adheres to the standard ATX form factor.
Watch Out For
- The 135mm fan can generate noticeable noise when the system is under heavy load, potentially disrupting quiet environments.
- Professional reviews noted moderate ripple levels, which, while within spec, are not best-in-class.
- Testing revealed some indications of thermal stress, suggesting it might run warmer internally under sustained high loads.
- Despite its Cybenetics Platinum rating, it did not quite meet the stricter 80 Plus Platinum efficiency at full load.

What Buyers Say
Users frequently point out the quiet operation at lower loads and the benefit of the fully modular cables for clean builds. The inclusion of a native 12V-2x6 cable for modern GPUs is a recurring positive, making it feel future-proof. However, some professional reviews noted moderate ripple and noise, and the fan can become audible when the PSU is heavily loaded. There's also some general caution in community discussions regarding ASRock PSUs, though specific issues for this model are less common.
“Look, it's got the new cable for my 4090 and it's quiet most of the time, so I'm happy, but yeah, when I'm really pushing it, I can hear the fan spin up.”
Common Praise
- Fan remains off during light to medium system loads, resulting in silent operation.
- Fully modular cables simplify installation and allow for cleaner internal PC aesthetics.
- Includes a native 12V-2x6 power cable, ready for high-power PCIe 5.1 graphics cards.
- The dual-color design on the 12V-2x6 connector helps ensure it's properly seated.
- Many users appreciate the white color option and matching white cables for themed builds.
- The 10-year warranty provides extended peace of mind.
Common Complaints
- The 135mm fan can produce noticeable noise when the power supply is under high load.
- Professional testing identified moderate ripple levels, which could be a concern for some enthusiasts.
- Some reviews mentioned signs of thermal stress during rigorous hot testing.
- While Cybenetics Platinum, it did not quite hit 80 Plus Platinum efficiency at maximum output.
Ownership Tips
- The iCool fan mode genuinely keeps the system quiet during web browsing or light gaming, with the fan only kicking in during intense sessions.
- The flat, flexible cables are a blessing for routing, especially in tighter cases.
- The dual-color 12V-2x6 connector is a small but helpful detail for making sure that critical power connection is secure.
- Even with the fan spinning up under load, it's not an obnoxious whine, more of a consistent airflow sound.

Buying Guide
When you're picking a power supply, you're basically choosing the heart of your PC. It needs to deliver enough stable power for all your components, especially your CPU and graphics card. You also want it to be efficient, so it doesn't waste electricity as heat, and quiet, so it doesn't sound like a jet engine. Modularity helps keep your case tidy, and a good warranty means the manufacturer stands behind their product.
Wattage (1000W)
This is the total power your PSU can supply. Think of it like the horsepower of a car; you need enough to power all your components, especially your graphics card and CPU, with some headroom for future upgrades or power spikes.
80 Plus Gold & Cybenetics Platinum
These are efficiency ratings. They tell you how much of the power drawn from the wall actually goes to your components versus being lost as heat. Gold and Platinum are high tiers, meaning less wasted energy, lower electricity bills, and less heat generated inside your PC.
ATX3.1 & PCIe5.1 Ready
This means the PSU is designed for the latest PC hardware standards. PCIe 5.1 is crucial for new, power-hungry graphics cards, ensuring they get stable power through a dedicated 12V-2x6 cable, preventing issues like power delivery problems or melting connectors.
Fully Modular
This refers to the cables. Fully modular means you can detach every cable from the PSU. This is a huge win for cable management, as you only plug in the cables you need, leading to a cleaner build and better airflow inside your case.
Alternatives
If this power supply doesn't fit your needs, look for units with higher 80 Plus efficiency ratings like Titanium for maximum energy savings, or lower wattage if your components don't require 1000W, to potentially save money.
