Chieftec APB-500B8 is a 500 W internal power supply from the VALUE series for powering a desktop PC. Its AC input is limited to 230 V, making it suitable for a build designed for that voltage.
It has 80PLUS White efficiency for 230 V input. A 120 mm silent fan provides cooling, and the listed PSU length is 140 mm, useful to check against the space available in the case.
The 500 W output and 140 mm length can be compared with the desktop system’s power and fit requirements.
