Dimension Scores
Achieves 80 Plus Platinum certification with up to 93.9% efficiency at 50% load and provides 1000W continuous power with a single 83.3A 12V rail.
Features a 135mm Silent Wings fan that produces only 28.9 dB(A) at 100% load, making it exceptionally quiet.
Incorporates Japanese 105°C capacitors and full bridge LLC technology for signal stability and reliability, backed by a 10-year warranty.
Offers fully modular cable management, allowing users to connect only the necessary cables for a cleaner build and improved airflow.
Best For
- PC builds with high-end, power-hungry PCIe 5.0 GPUs like the RTX 4090 or future generations.
- Users prioritizing quiet operation, even under heavy system loads.
- Builders seeking a future-proof power supply compatible with ATX 3.0 specifications.
Not Recommended For
- Budget-focused builds where a lower wattage or efficiency rating would suffice for less demanding components.
- Compact ITX or SFF cases that require PSUs shorter than 160mm.
Watch Out For
- Some users have reported issues with the fan not spinning on arrival, particularly with open-box units, requiring an RMA process.
- While efficient, it won't match the extremely low-load efficiency of a Titanium-rated power supply, which might matter for systems idling frequently.
- The 12VHPWR connector, while standard for PCIe 5.0, requires careful seating to prevent issues, a common concern across all PSUs using this connector.

What Buyers Say
Users frequently highlight the near-silent operation of the 135mm Silent Wings fan, even when the system is under heavy load. The ATX 3.0 and PCIe 5.0 compatibility, including the 12VHPWR connector, is a recurring point of appreciation for future-proofing builds. While generally praised for its reliability and efficiency, there was one report of a fan not spinning on an open-box unit, though customer service was responsive for an RMA.
“Man, this thing is quiet, like, I literally can't hear it over my case fans, and it powers my 4080 Super without breaking a sweat, but seriously, check the fan when you get it, mine was dead on arrival, but they sorted it out fast.”
Common Praise
- The 135mm Silent Wings fan keeps the PSU virtually inaudible during operation.
- Provides full ATX 3.0 and PCIe 5.0 support, making it ready for current and upcoming GPUs.
- The 80 Plus Platinum efficiency helps reduce power consumption and heat output.
- Modular cables simplify the building process and improve internal case aesthetics.
- Handles power spikes from demanding graphics cards without issues.
Common Complaints

Buying Guide
When you're picking a power supply, you're basically choosing the heart of your PC. It needs to deliver enough juice for all your components, especially your graphics card, without making a racket or wasting electricity. You also want it to be reliable so it doesn't fry your expensive parts. This one is built for modern, power-hungry systems.
Wattage (1000W)
This is the total power your PSU can supply. Think of it like the horsepower of a car; 1000W is a lot, meaning it can handle high-end CPUs and GPUs, especially if you plan on overclocking or running multiple drives.
80 Plus Platinum Efficiency
This rating tells you how much power from the wall actually reaches your components, with Platinum being very efficient (up to 93.9%). Higher efficiency means less wasted electricity as heat, saving you a bit on your power bill and keeping your system cooler.
ATX 3.0 & PCIe 5.0
This is the latest standard, specifically designed for modern graphics cards that can draw massive, sudden bursts of power (power excursions). If you're getting a new high-end GPU, you want a PSU with these specs to ensure stability and compatibility.
Modular
A modular PSU lets you detach any cables you don't need. This makes your PC build much tidier, improves airflow inside the case, and generally makes installation easier than dealing with a spaghetti of unused wires.
Alternatives
If you need a more budget-friendly option, look for an 80 Plus Gold rated PSU with slightly lower wattage if your components aren't as demanding. For the absolute best efficiency at all loads, consider an 80 Plus Titanium rated power supply.
