Advantages

The Akyga AK-S1-300 offers a compact SFX design that fits small form-factor builds while providing 300 W of power. Its set of connectors (20+4 ATX, P4 CPU, Molex, SATA) supports common PC configurations. The 80 mm fan with automatic speed control reduces noise and helps maintain temperatures, and the built-in protections and PFC filter improve reliability and protect connected components. The unit’s construction from galvanized steel adds mechanical durability.
