Product information

Description

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.

Suitable for

  • Basic desktop PCs and office computers
  • Systems with single discrete graphics cards (limited power draw)
  • Upgrading old PCs that require SATA and Molex connectors
  • Builds that need a compact 500 W ATX PSU

How to use

Install the Akyga AK-B1-500 into a compatible ATX case and secure it with screws. Connect the 20+4 pin ATX cable to the motherboard and the P4 4-pin to the CPU power header if required. Attach the PCI-E 6+2-pin to the graphics card when needed and use the SATA and Molex connectors to power drives and peripherals. Ensure the mains cable is connected to a grounded AC outlet (230 V) and use the manual switch on the unit to turn power on or off. Verify cable routing and clear airflow around the 120 mm fan before powering the system.

Usage recommendations

Use this 500 W PSU in systems with moderate power requirements; avoid deploying it in high-end gaming rigs or multi-GPU workstations. Keep ventilation clear and perform periodic dust cleaning to maintain cooling efficiency and prolong service life.
