Pros & Cons
👍 Pros
- Achieves 80 PLUS Gold certification, offering high efficiency of 90% (115VAC) / 92% (220VAC to 240VAC) or higher under typical loads.
- Features a compact SFX form factor, making it suitable for smaller PC builds where space is a premium.

- Equipped with heavy-duty protections including OVP, UVP, OCP, OPP, and SCP, safeguarding components from electrical issues.
- Comes with a substantial 7-year warranty, providing long-term assurance and support for the product.
👎 Cons
- The 650W power output may not be sufficient for extremely high-end systems with multiple power-hungry components.
- The SFX form factor, while compact, might require an adapter bracket for installation in larger ATX cases.
- A 92mm fan might generate more audible noise under heavy load compared to larger 120mm or 140mm fans found in ATX PSUs.
- Being an SFX power supply, it may have fewer modular cable options or connection types compared to full-sized ATX units.
- Efficiency ratings are "typical loads," meaning peak efficiency may not always be sustained under all operational conditions.
