- The white edition of the PSU ships with grey-colored modular connectors, which clashes with white builds.
Dimension Scores
It's 80 Plus Platinum certified, achieving 91.4% average efficiency at 115 VAC and peaking at 94.2% at 45% load.
Features 0dB technology for silence at low loads, but the dual ball bearing fan can become audible with bearing noise under load, and some units have coil whine.
Utilizes GaN MOSFETs, large ROG heatsinks, dual ball fan bearings, and top-tier Japanese capacitors from Nippon Chemi-Con, Nichicon, and Rubycon.
It's fully modular with flexible, sleeved cables and a native 12V-2x6 connector, simplifying installation and reducing clutter.
Best For
- High-performance gaming PCs with power-hungry, next-gen GPUs requiring ATX 3.1 and PCIe 5.1.
- Enthusiast builds prioritizing power stability and efficiency for overclocking or demanding workloads.
- Users who value a 10-year warranty and premium internal components.
Not Recommended For
- Budget-conscious builders, as its features and performance come at a higher cost.
- Silence-focused builds where any fan noise or potential coil whine is unacceptable.
Watch Out For
- Some units exhibit coil whine under load, with users returning them due to the noise.
- The white version of the PSU includes grey modular cable connectors, which can detract from a clean white aesthetic.
- Despite 0dB technology, the dual ball bearing fan can generate an audible bearing noise at low speeds when active.
- The 12V rail experienced a drop below 3.2V during the 200% load transient test, though it still met ATX 3.1 standards.

What Buyers Say
Some users have reported coil whine issues, causing them to return the unit, which is a bummer for a premium PSU. However, many others praise its quiet operation during light use due to 0dB technology and its future-proofing with ATX 3.1 and PCIe 5.1 compliance. The build quality, with GaN MOSFETs and large heatsinks, gets consistent mentions for its robust design. The fully modular cables are also a hit for making builds cleaner.
“Man, this thing is a beast for my 4090, but seriously, the coil whine on mine is driving me nuts, had to send it back.”
Common Praise
- Quiet operation during light gaming or low loads due to 0dB technology.
- ATX 3.1 and PCIe 5.1 readiness with a native 12V-2x6 connector for new GPUs.
- High efficiency, meeting 80 Plus Platinum and Cybenetics Platinum standards.
- Premium internal components, including GaN MOSFETs and Japanese capacitors.
- Fully modular design with flexible, sleeved cables for clean builds.
- The 10-year warranty provides long-term peace of mind.
Common Complaints
- Audible coil whine reported by some users, particularly under load.
- Fan bearing noise can be heard at low speeds once the fan engages.
- The white version comes with grey cable connectors, which doesn't match a pure white build.
- The 12V rail showed a drop in the 200% load transient test.
Ownership Tips
- The 0dB mode actually works, keeping things silent until you really push your system.
- Cable routing is a breeze with the fully modular design, and the cables themselves feel premium.

Buying Guide
When you're looking at a power supply, you're basically buying the heart of your PC. It needs to deliver consistent, clean power to all your expensive components, especially your graphics card. Don't cheap out here; a bad PSU can take out your whole system. You want enough wattage for your current and future components, and good efficiency means less wasted electricity and less heat. Pay attention to the ATX standard and connector types for compatibility with modern hardware.
Wattage (1000W)
This is the total power your PSU can supply. Think of it like the horsepower of a car; you need enough to move your system efficiently, especially if you have a high-end GPU or plan to upgrade. Too little, and your system won't run stably; too much, and you're just spending extra money.
80 Plus Platinum Certified
This rating tells you how efficiently the PSU converts AC power from your wall into DC power for your PC. Platinum means it's super efficient (around 90-94% efficient), like a fuel-efficient car. Less wasted energy means lower electricity bills and less heat generated inside your case.
ATX 3.1 & PCIe 5.1
These are the latest standards for power supplies, crucial for compatibility with modern, power-hungry graphics cards. It ensures the PSU can handle transient power spikes from GPUs without tripping, like a robust electrical system in a house that won't blow a fuse when you turn on multiple appliances at once.
Fully Modular
This means you only plug in the cables you actually need. It's like having custom-length cables for your car's engine; it keeps your PC case tidy, improves airflow, and makes building or upgrading much easier than having a bunch of unused cables cluttering things up.
Alternatives
If this PSU is overkill or too pricey, look for an 80 Plus Gold rated, ATX 3.0 compatible power supply with 750W-850W if your GPU isn't top-tier, or consider units with a Cybenetics A- or B noise rating if absolute silence is your priority.
