Tacens APB550B power supply unit 550 W 20+4 pin ATX ATX Black

The Tacens Anima APB550 550 W power supply unit provides stable power delivery for desktop PCs with a maximum continuous output of 550 W. Designed for standard ATX systems, it includes a 20+4 pin ATX motherboard connector and a fixed cable layout. The unit is 80 PLUS Bronze certified for improved energy efficiency and operates on AC input voltage of 220–240 V at 50–60 Hz. An active cooling system with a 120 mm fan maintains thermal balance while producing low acoustic output.

Advantages

The Tacens Anima APB550 combines a compact form factor with efficient power conversion, offering reliable voltage regulation and steady current for common consumer and office builds. Its 80 PLUS Bronze certification reduces wasted energy and heat compared with non-certified units. The built-in 120 mm fan provides effective cooling and a low noise level of approximately 14 dB under typical load, making it suitable for environments where low acoustic impact is desirable. The black finish and standard dimensions allow easy installation in a wide range of mid-tower and compact cases.

Suitable for

• Home and office desktop PCs with moderate power demands
• Budget gaming builds with a single mid-range graphics card
• System upgrades where a reliable fixed-cable PSU is acceptable
• Compact or mid-tower cases that support standard ATX power supplies

How to use

Install the power supply into the computer case aligning the mounting holes with the chassis. Connect the 20+4 pin ATX cable to the motherboard main power socket, and attach additional fixed cables to peripheral devices and drives as required by the system configuration. Verify the input voltage selector (if present) and connect the unit to a grounded AC outlet within the specified 220–240 V, 50–60 Hz range. After connecting all components, power on the system and monitor voltages and fan operation during initial start-up to confirm stable operation.

Recommendations

For reliable long-term operation, ensure adequate airflow inside the case and avoid obstructing the 120 mm fan intake. Use a surge protector or UPS to protect the power supply from voltage spikes. Match the 550 W capacity to the total system load, considering peak currents of the CPU and graphics card, and replace the unit if you plan significant upgrades that increase power requirements beyond the PSU’s rated output.
