Dimension Scores
The unit is 80 Plus Gold and Cybenetics Platinum certified, achieving 90.8% efficiency at 115 VAC, which is above the standard Gold rating.
It's Cybenetics Lambda A certified for low noise and quiet at low loads, but Tom's Hardware reported it gets noisy when heavily stressed.
Features 100% Japanese capacitors and comes with a 10-year warranty, indicating a focus on long-term durability.
The fully modular design with flat, flexible cables, including a 650mm 12V-2x6 cable, makes routing and organizing cables straightforward.
Best For
- High-end PC builds with power-hungry GPUs requiring PCIe 5.1 power.
- White-themed custom PC builds where aesthetics are a priority.
- Users seeking a long-term investment due to the 10-year warranty and Japanese capacitors.
Not Recommended For
- Silence-focused builds that frequently push the PSU to high loads.
- Budget-conscious builders looking for the absolute lowest price point without specific aesthetic needs.
Watch Out For
- The fan can get loud when the system is heavily stressed, so don't expect silent operation during intense gaming or rendering sessions.
- While voltage regulation is tight, Tom's Hardware reported moderate ripple levels, which might not be ideal for overclockers pushing their hardware to the absolute limit.
- The 12V-2x6 cable is dual-color, which might clash with some specific single-color white aesthetic preferences, despite being generally white.

What Buyers Say
People are really digging the white aesthetic and the included white cables, which is a big deal for themed builds. The 10-year warranty and the fact it's ATX 3.1 and PCIe 5.1 ready are also frequently mentioned as key selling points, making it feel future-proof. However, some professional reviews point out that while it's quiet at low power draw, it can get noticeably louder when your system is really pushing it. The moderate ripple levels were also a specific technical detail noted by one reviewer.
“Needed a white PSU for my new build, and this one fit the bill perfectly with the 1000W and the 12V-2x6 cable. It's quiet enough for my daily stuff, but yeah, when I'm gaming hard, I can definitely hear the fan kick in. Still, ten years warranty, can't complain too much!”
Common Praise
- The white color and matching cables look fantastic in white PC builds.
- It's fully modular, making cable routing much cleaner and easier.
- The 10-year warranty provides a lot of peace of mind for long-term use.
- Native PCIe 5.1 12V-2x6 cable is included and ready for modern GPUs.
- Quiet operation during light computing tasks.
Common Complaints
- The fan noise increases significantly under heavy system loads.
- Moderate ripple levels were observed in testing, which isn't ideal for extreme overclocking.
- Doesn't offer unique features to stand out from other PSUs in its class.
Ownership Tips
- The flat cables are genuinely flexible and make routing through tight spaces in a case less of a headache.
- The dual-color aspect of the 12V-2x6 cable is subtle but a nice touch if you're into the details.
- The iCOOL fan control actually works, keeping things silent until you really start drawing power.

Frequently Asked Questions
Is this power supply compatible with NVIDIA's RTX 40-series graphics cards?
Yes, it's PCIe 5.1 ready and includes a native 12V-2x6 cable, which is what the latest NVIDIA GPUs use for power.
What does 'fully modular' mean for cable management?
Fully modular means you only connect the cables your system needs, which reduces clutter inside your PC case and improves airflow.
How long is the warranty on this power supply?
ASRock provides a 10-year warranty for this power supply, indicating confidence in its durability and component quality, like the Japanese capacitors.
Is the fan always on, or does it have a silent mode?
It features iCOOL Intelligent Fan Control Mode, which means the fan can operate semi-passively, staying off or spinning at low RPMs under light loads for quieter operation.
What are the physical dimensions of this power supply?
The power supply measures 150mm x 150mm x 86mm, which is a standard ATX form factor size.
Buying Guide
When you're looking at a power supply, you're basically buying the heart of your PC. It needs to supply enough wattage for all your components, especially your graphics card, and do it efficiently without wasting a ton of electricity as heat. You also want it to be reliable so it doesn't fry your expensive parts. Pay attention to the efficiency rating and the warranty, as those tell you a lot about its quality and expected lifespan.
Wattage (1000W)
This is the total power your PSU can deliver. A 1000W unit is for high-end systems with powerful CPUs and GPUs, ensuring they get all the juice they need, even during peak performance. Think of it like the horsepower of a car; more means it can handle heavier loads.
80 Plus Gold & Cybenetics Platinum
These are efficiency ratings. Gold means it's at least 87-90% efficient, and Platinum is even higher (90-92%). Higher efficiency means less wasted electricity as heat, lower electricity bills, and a cooler running system. It's like getting more miles per gallon from your car.
ATX3.1 & PCIe5.1 Ready with 12V-2x6 Cable
This tells you the PSU is built for the latest hardware. ATX3.1 is the newest power supply standard, and PCIe5.1 with the 12V-2x6 cable is specifically for the newest, most power-hungry graphics cards. Without this, you might need adapters, which aren't ideal. It's like having the right plug for your new appliance.
Fully Modular
A fully modular PSU lets you detach every single cable that isn't needed. This is a huge win for keeping your PC build tidy, improving airflow, and making future upgrades or troubleshooting much easier. Imagine having only the necessary wires in your car's engine bay instead of a tangled mess.
Alternatives
If this wattage is overkill, look for 750W or 850W PSUs with similar efficiency ratings. If silence is your absolute top priority, search for PSUs with higher Cybenetics Lambda ratings for quieter operation under load.
