Dimension Scores
The PSU is 80 Plus Gold certified with up to 94.3% efficiency and handles power excursions up to double its rated 750W.
Its semi-passive 120mm fan stops completely under low load, making it exceptionally silent in those scenarios.
It uses LLC topology for voltage regulation, but there are conflicting reports on the bulk capacitor quality (85°C vs 105°C), which could indicate inconsistency.
The fully modular cable design allows for clean builds and improved internal airflow.
Best For
- Gaming PCs with next-generation PCIe 5.1 GPUs requiring a 12V-2x6 connector.
- Quiet PC builds where fan noise under low load is a concern.
- Systems needing efficient power delivery and stable voltage regulation for modern components.
Not Recommended For
- Users sensitive to minor clicking noises from internal components during light use.
- Builders who prioritize readily available and responsive customer support.
- Budget-constrained builds where every dollar counts, given its entry-level price band but specific features.
Watch Out For
- A 'slight click' can occur infrequently during low power states, which some users find distracting.
- The type of bulk capacitors (85°C or 105°C) might vary between units, potentially impacting long-term reliability for some users.
- Be quiet!'s customer support has been noted as difficult to reach.

What Buyers Say
Some users have noticed a faint clicking sound, especially when the PC is doing light tasks like browsing, which seems to be a bypass relay engaging and disengaging as the PSU switches efficiency modes. This isn't a sign of failure, but it's something to be aware of if you're sensitive to minor noises. There's also some chatter about the internal capacitors, with a few people wondering if be quiet! is using different quality parts in various production runs. If you need support, some users have found be quiet!'s customer service to be unresponsive.
“This thing is quiet when it's supposed to be, but that little click when I'm just watching YouTube is kinda annoying, makes me wonder if something's off even though everyone says it's normal.”
Common Praise
- The fan stays off during low loads, making the system very quiet.
- The native 12V-2x6 connector is ready for new graphics cards.
- Cables are fully modular, making installation and routing straightforward.
- Provides stable power even with transient loads from modern GPUs.
Common Complaints
- A subtle clicking noise can be heard during low power states.
- Uncertainty about the quality of internal bulk capacitors (85°C vs 105°C).
- Difficulty in getting a response from customer support.
Ownership Tips
- The clicking sound from the bypass relay is most noticeable during periods of very low system activity, not under heavy load.
- The modular cables are stiff enough to hold their shape for routing but flexible enough for installation.
- The PSU runs cool, even under moderate gaming loads, likely due to its efficiency and semi-passive fan design.
Frequently Asked Questions

Yes, it supports next-generation PCIe 5.1 graphics cards with a native 12V-2x6 connector, and also includes four 6+2-pin connectors for current-gen GPUs.
Is this power supply quiet?
Yes, it features a semi-passive 120mm fan that completely turns off under low loads, contributing to exceptionally quiet operation.
What is the efficiency rating?
It is 80 Plus Gold certified, with an efficiency rating of up to 94.3%.
Are the cables modular?
Yes, it has fully modular cables, which helps with cable management and improves airflow inside your PC case.

Buying Guide
When you're looking at a power supply, you're basically picking the heart of your PC. It needs to provide enough wattage for all your components, especially your graphics card, and do it efficiently so you're not wasting electricity or generating too much heat. Modularity helps keep your case tidy, and features like ATX 3.1 and PCIe 5.1 connectors mean it's ready for the newest, most demanding parts.
Wattage (750W)
This is how much power the unit can deliver. Think of it like the engine size in a car; too small, and your PC won't run properly, especially under load. 750W is enough for most mid-to-high-end gaming systems.
80 Plus Gold Certification (up to 94.3% efficiency)
This rating tells you how much power from the wall actually reaches your components, versus how much is lost as heat. Gold means it's very efficient, like a fuel-efficient car, saving you money on your electricity bill and keeping your PC cooler.
ATX 3.1 & PCIe 5.1 (12V-2x6 connector)
These are the latest standards for power supplies, specifically designed for modern, power-hungry graphics cards. The 12V-2x6 connector is a dedicated cable for new GPUs, ensuring stable power delivery without needing adapters.
Modular (Fully Modular)
This refers to whether the cables detach from the power supply. Fully modular means you only plug in the cables you need, like only taking the groceries you'll use out of the bag. This makes your PC build cleaner and improves airflow.
Alternatives
If this PSU doesn't fit, look for units with higher wattage (850W+), a different efficiency rating (Platinum or Titanium for more savings), or a different form factor if you have a smaller case.
