Power supply unit Akyga AK-B1-500, 500 W, ATX 2.31, 20+4 pin, 120 mm fan, non-modular

Akyga AK-B1-500 500 W is a basic ATX power supply unit designed to provide stable power to desktop computers. Built from quality components, it supports ATX12V 2.0 specifications and delivers 500 W of total power. The unit includes a 20+4 pin ATX motherboard connector, a P4 4-pin connector, a PCI-E 6+2-pin connector, three SATA connectors, two Molex connectors and a mini-Molex connector. Active cooling is provided by a 120 mm fan with automatic speed control, and the PSU features a manual power switch for safe shutdown. Efficiency is rated above 70%, and the product includes protection circuits (OVP, OCP, OPP, OTP, SCP) and a PFC filter to stabilize output and protect system components.

Advantages

The power supply offers a complete set of common connectors for modern and legacy components, a 120 mm quiet fan for effective cooling, and compliance with ATX12V 2.0 for compatibility with multi-core platforms. Built-in protection mechanisms and a PFC filter increase the safety and stability of the computer system, while an MTBF of approximately 100,000 hours indicates long-term reliability.
