General description The 20/24 4/6/8 Pin PC Computer Power Supply Tester is a robust voltage tester designed for ATX, ITX, and BTX power supplies. It features an easy-to-read digital LCD display that indicates the voltage status, making it suitable for both ambitious hobby users and quick function checks in specialist shops. Technical specifications Voltage source: 20/24 pin (ATX connector) Voltage test: +12V, -12V, +5V, -5V, +3.3V, 5V stand (SB) 12V output good (PG) Connections: Floppy, HDD, CD-ROM, SATA, 4 pin (P4), 8 pin (Dual CPU), 6 pin (PCI-Express) Installation Plug the 24-pin power supply and P4, P6, or P8 into the corresponding socket of the tester. Turn on the power supply to initiate testing. Usage Upon powering on, a buzzer will sound “DuDu”. If there is no flickering on the display, the power supply output voltage is normal. If a voltage signal is not recognized or the voltage value exceeds normal levels, a long “DuDu” buzzer will sound, indicating a power supply failure.
