👎 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.
