How to Use
- Plug the PSU's 24-pin (or 20-pin) connector and any additional connectors (P4, P6, P8) into the corresponding ports on the tester.
- Switch on the power supply. A short "beep" and steady LCD readings confirm normal voltage output.
- If any voltage is absent or out of acceptable range, the buzzer will sound a long alert and the corresponding reading will flash — indicating the PSU requires further inspection or replacement.

Frequently Asked Questions
Q: Does the ALLOYSEED ATX power supply tester require batteries?
A: No — the tester draws power directly from the PC power supply being tested through the 20/24-pin ATX connector. No external batteries or additional power source is needed.
Q: Which PSU connectors does this LCD power supply tester support?
A: It supports a wide range of connectors including ATX 24-pin, ATX 20-pin, SATA, 8-pin & 4-pin CPU power, PCI-E 6-pin graphics, floppy disk, and ATE hard disk interfaces — making it compatible with most standard desktop ATX, BTX, and ITX power supplies.
Q: How do I know if my power supply has passed or failed the test?
A: When all voltages are within normal range, the tester emits a short beep and the LCD displays stable readings. If a voltage is missing or outside the acceptable range, the tester sounds a sustained buzzer alert and the affected voltage reading will flash on the display, indicating a potential PSU issue.
Q: Is this tester suitable for beginners with limited technical experience?
A: Absolutely. The ALLOYSEED digital LCD tester features a straightforward plug-and-test design with a clearly labeled display and audible alerts, making it accessible for hobbyists, DIY PC builders, and professionals alike.
