Performance
The Be Quiet! System Power 10 650W performed consistently during my tests. It delivered stable power to my components and remained silent even under heavy load. While not as efficient as some higher-tier PSUs, the Bronze rating ensures reasonable energy savings and adequate thermal performance.
I used the PSU to power a system with a Ryzen 5 5600X CPU, an RTX 3060 Ti graphics card, and other components, pushing it to its limits during gaming and rendering workloads. It handled everything without hiccups, maintaining steady voltage levels and keeping the system cool.
Pros & Cons
Pros
- Affordable price point.
- Quiet operation.
- Stable power delivery thanks to DC-to-DC technology.
- 80 Plus Bronze certification for decent efficiency.
- Comes with a comprehensive set of cables for most PC builds.
Cons
- Non-modular design limits cable management flexibility.
- Efficiency levels are not as high as higher-tier PSUs.
Final Verdict
Overall, the Be Quiet! System Power 10 650W is a solid choice for budget-conscious builders who prioritize quiet operation and stable power delivery. It’s a reliable power supply that gets the job done without breaking the bank. However, if you need modular cables or want the best efficiency possible, you might want to consider a higher-tier PSU.
I would recommend the Be Quiet! System Power 10 650W to anyone building a system with a mid-range CPU and GPU, or for anyone on a tight budget who still wants a quality power supply.
