Dimension Scores
Achieves 80 PLUS Platinum and Cybenetics Platinum efficiency up to 94.0% and handles power excursions up to double its 1000W rating.
Features semi-passive zero-RPM cooling and a 140mm Pure Wings 3 fan for quiet operation, though some users report audibility above 800W.
Utilizes LLC topology for advanced voltage regulation and stability, with a 10-year warranty.
Includes a 90° angled 12V-2x6 connector and modular ribbon-style cables, but some users report issues with cable length and limited PCIe sockets for certain GPU configurations.
Best For
- High-end gaming PC builds with current and next-gen PCIe 5.1 graphics cards.
- Workstations requiring stable 1000W power delivery and high energy efficiency.
- Users building quiet systems who value zero-RPM fan operation at low loads.
- PC enthusiasts seeking a future-proof power supply with ATX 3.1 compatibility.
Not Recommended For
- Budget-conscious builds, given its entry-plus price band.
- Compact ITX or SFF cases where the 3.4 kg weight and physical size might be an issue.
- Users who need absolute silence under all load conditions, as fan noise can become audible at high wattage.
Watch Out For
- The 12V-2x6 cable might be too short for some setups, especially with top-mounted PSUs and GPUs with reversed connectors, leading to potential cable management issues or the need for an extension.
- A Reddit user reported severe coil whine from the PSU even during light loads (1080p, 60fps), indicating potential noise issues beyond fan operation.
- The semi-passive fan has a post-ventilation period of 2-5 minutes after cooldown, which means it won't immediately stop spinning after a heavy load.
- GPUs requiring three separate 8-pin PCIe connections might be problematic as the PSU only has two PCIe sockets, potentially forcing the use of a daisy-chain cable.

What Buyers Say
While marketed for its quiet operation, some users have reported that the fan can become noticeable when the PSU is under heavy load, specifically above 800 watts. There are also isolated reports of coil whine, even during light usage, which can be a dealbreaker for silence-focused builds. The included 90-degree 12V-2x6 cable is a thoughtful addition, but its length can be a problem for specific case layouts, and the number of PCIe sockets might necessitate daisy-chaining for some GPUs.
“Man, I bought this 'cause everyone said it was silent, but my GPU still whines, and the fan kicks in louder than I expected when I'm actually gaming. Plus, that 12VHPWR cable is barely long enough for my case, kinda annoying.”
Common Praise
- The 90° angled 12V-2x6 connector is a thoughtful inclusion for modern GPU installations.
- The semi-passive cooling keeps the fan off during low power draw, contributing to a quiet desktop experience.
- The 80 PLUS Platinum and Cybenetics Platinum efficiency ratings are consistently achieved, leading to lower power consumption.
- Handles power excursions up to double its rated 1000W, providing stability for demanding hardware.
- The 10-year warranty provides long-term peace of mind.
Common Complaints
- Fan noise becomes clearly audible when the PSU is consistently pushed above 800 watts.
- One user experienced severe coil whine from the PSU even at 1080p 60fps.
- The stock 12V-2x6 cable can be too short for top-mounted PSUs and GPUs with reversed connectors.
- Only two PCIe sockets are available, which can be limiting for GPUs requiring three separate 8-pin connections.
- At over 3.4 kg, the PSU is heavier than some alternatives, potentially complicating compact builds.
Ownership Tips
- The semi-passive fan has a noticeable 2-5 minute cooldown period where it continues to spin after the system is shut down or under low load.
- Cable routing can be tricky in some cases due to the length of the 12V-2x6 cable, requiring careful planning or aftermarket solutions.
- The PSU's weight is significant, making it less ideal for frequent system moves or very lightweight builds.
- The 'be quiet!' branding on the mesh front is subtle, which might appeal to those who prefer a minimalist aesthetic.

Buying Guide
When you're looking at a power supply like this, you're really buying the heart of your PC. It's not just about the wattage number; it's about how efficiently it converts wall power into usable power for your components, how stable those power lines are, and how quietly it does its job. You want enough wattage for your current and future components, but also a high efficiency rating to save on your electricity bill and keep things cool. Don't cheap out here, because a bad PSU can take out your whole system.
Wattage (1000W)
This is the total power your PSU can deliver. Think of it like the horsepower of a car; you need enough to run all your components (CPU, GPU, storage) comfortably, especially if you have a high-end graphics card or plan to upgrade. 1000W is a lot, so it's ready for powerful systems.
80 PLUS Platinum & Cybenetics Platinum Efficiency (up to 94.0%)
This rating tells you how much power the PSU wastes as heat. Platinum means it's super efficient, converting at least 90% of the power it draws into usable electricity. This means less wasted energy, lower electricity bills, and less heat generated inside your PC.
ATX 3.1 & PCIe 5.1 Ready (with 12V-2x6 connector)
This is about future-proofing. ATX 3.1 is the latest standard for power supplies, and PCIe 5.1 is for the newest, most power-hungry graphics cards. The included 12V-2x6 connector is specifically designed for these new GPUs, ensuring compatibility and stable power delivery without needing adapters.
Semi-passive Zero-RPM Cooling
This feature means the fan in the PSU won't spin at all when your PC isn't under heavy load, making your system completely silent during light tasks like browsing or watching videos. The fan only kicks in when needed, keeping noise levels down.
Alternatives
If this PSU doesn't fit, look for models with a higher number of dedicated PCIe 8-pin connectors for multi-GPU setups or GPUs with multiple power inputs, or consider PSUs with a longer 12V-2x6 cable if your case layout requires it.
