AI Verdict
A 750W ATX 3.1, 80 Plus Gold, fully modular PSU with a 12V-2x6 connector for builders needing modern GPU support on a budget.
This 750W ATX 3.1 PSU is a situational fit because it offers essential modern features like a native 12V-2x6 connector and 80 Plus Gold efficiency at an entry-level price point. However, potential fan noise under load and a shorter 5-year warranty compared to premium options mean it's not for everyone.
If you need quieter operation or a longer warranty, look for PSUs with fluid dynamic bearing (FDB) fans and 10-year warranties from more established manufacturers.

- Complies with ATX 3.1 specifications, ensuring compatibility with newer system architectures.
- Achieves up to 92% power conversion efficiency under typical loads, certified 80 Plus Gold.
- Features 105°C Japanese capacitors, contributing to long-term stability.
- Fully modular design allows connecting only necessary cables, improving internal airflow.
Cons
- The 5-year manufacturer warranty is shorter compared to the 7-10 year warranties offered by many premium power supplies.
- Some users have reported the temperature-controlled 120mm fan can become noisy under heavy system loads.
- Despite being advertised as 'ultra-flexible,' some users find the shark-pattern cables to be a bit stiff, making neat routing challenging in certain setups.
- The brand's PSU track record is considered thin by some in the PC building community, leading to limited long-term reliability data for this specific model.
- Weighing over 3 lbs, the unit is on the heavier side, which can make installation cumbersome in compact PC cases.
Dimension Scores
The 80 Plus Gold certification indicates up to 92% conversion efficiency, which is above average for its price band.
It features a temperature-controlled 120mm hydraulic bearing fan for smart cooling, but some users report it can be noisy under load.
The inclusion of 105°C Japanese capacitors suggests a focus on component quality, though the brand's overall PSU track record is less established.
The fully modular design with ultra-flexible cables allows for clean builds, although some users find the cables less flexible than expected.
Best For
- PC builds requiring a native 12V-2x6 connector for a modern GPU.
- Budget-conscious builders prioritizing ATX 3.1 and PCIe 5.1 readiness.
- Systems where clean cable management is desired due to the fully modular design.
Not Recommended For
- Users building ultra-quiet PCs where any fan noise under load is unacceptable.
- Those seeking the longest possible manufacturer warranty (e.g., 7-10 years).
- Very compact ITX builds where the unit's weight and potentially stiff cables could complicate installation.
Watch Out For
- The 120mm hydraulic bearing fan, while temperature-controlled, has been reported by some users to generate noticeable noise when the system is under heavy load.
- The advertised 'ultra-flexible' shark-pattern cables can actually be somewhat stiff for some users, making precise cable routing and management more difficult than expected.
- The unit's weight, exceeding 3 lbs, might be cumbersome for builders working in tight spaces or aiming for a lightweight system.
- The 5-year warranty is shorter than the 7-10 year coverage often provided by more established PSU brands, which could be a concern for long-term peace of mind.

What Buyers Say
The PCCOOLER KN750 is positioned as an entry-level option for modern PC builds, offering ATX 3.1 and PCIe 5.1 readiness with a native 12V-2x6 connector. While it boasts 80 Plus Gold efficiency and Japanese capacitors, user feedback points to potential discrepancies between advertised features and real-world experience, particularly regarding cable flexibility and fan noise under load. The 5-year warranty is also shorter than many competitors, raising questions about long-term reliability for a brand that isn't a household name in PSUs.
“Okay, so it's got the new GPU plug and it's modular, which is cool, but seriously, those 'ultra-flexible' cables are kinda stiff and the fan gets loud when I'm actually gaming. I just hope it lasts past the 5 years.”
Common Praise
- The native 12V-2x6 connector is a selling point for powering newer GPUs without adapters.
- The fully modular design simplifies cable management, allowing for cleaner builds.
- The 80 Plus Gold certification provides confidence in its energy efficiency.
- The inclusion of 105°C Japanese capacitors is seen as a positive for internal component quality.
Common Complaints
- The 120mm fan can become audibly noisy when the power supply is under heavy load.
- Despite being marketed as 'ultra-flexible,' the cables are reported by some to be stiff and challenging to route neatly.
- The 5-year warranty is considered short compared to the longer warranties (7-10 years) offered by many competing PSU brands.
- There's a perceived lack of extensive long-term user reviews and independent testing data for this specific model, leading to some uncertainty about its reliability.
Ownership Tips
- The weight of the unit (over 3 lbs) can make it feel substantial, potentially complicating installation in smaller cases.
- The 'smart silent cooling' might not be silent for all users, especially those pushing their systems hard, as fan noise can become noticeable.
- Cable routing might require more force and patience than anticipated due to the reported stiffness of the 'ultra-flexible' cables.
- Long-term reliability is still a question mark for many users, given the brand's less established presence in the PSU market and the 5-year warranty.
Frequently Asked Questions

It is 80 Plus Gold Certified, meaning it delivers up to 92% conversion efficiency under typical loads, which helps reduce energy waste and heat output.
Are the cables easy to manage?
The PSU is fully modular, allowing you to connect only the cables your system needs. While advertised as 'ultra-flexible,' some users have found the cables to be a bit stiff, which might require more effort for neat routing.
Is this power supply quiet?
It features a temperature-controlled 120mm hydraulic bearing fan designed for smart silent cooling. However, some user reports indicate it can become noisy under heavy system loads.
What is the warranty period?

The PSU uses high-quality 105°C Japanese capacitors, which are known for contributing to better long-term stability and reliability in demanding operating conditions.
Buying Guide
When you're looking at a power supply, you're essentially buying the heart of your PC. It needs to deliver stable power to all your components without failing or making too much noise. You need to match its wattage to your system's needs, and consider features like modularity for easier building and efficiency for lower electricity bills.
ATX 3.1 & PCIe 5.1 12V-2x6
This means the PSU is built for the newest hardware. The 12V-2x6 connector is specifically for modern, power-hungry graphics cards, so you won't need clunky adapters that can be a fire hazard.
80 Plus Gold Certified
This certification tells you how efficiently the PSU converts wall power into usable PC power. Gold means it's at least 87-90% efficient, so less energy is wasted as heat, saving you a bit on your electricity bill and keeping your PC cooler.
Fully Modular Design
Think of it like customizable cables. You only plug in the cables your PC actually needs, which makes building much tidier, improves airflow inside your case, and generally looks way cleaner than having a bunch of unused wires crammed in.
Alternatives
If this PSU doesn't quite fit, search for power supplies with a 10-year warranty for longer peace of mind, or look for models specifically marketed for 'silent operation' if fan noise is a major concern.
