Who should skip it
You should look at another option if you need a tool for measuring current or resistance. This device only checks voltage and the Power Good signal. It does not provide load testing capabilities, so it cannot verify performance under stress. If you require detailed analysis of ripple or transient response, this simple diagnostic tool is insufficient. It is best for basic pass/fail checks rather than deep electrical troubleshooting.
Verdict: The BUBUCAM LCD Power Supply Tester is a straightforward tool for verifying voltage outputs across multiple PC form factors. Its clear display and audible alerts make it a reliable choice for basic power supply diagnostics.

This compatibility covers most standard desktop units. You do not need to install any software or drivers. The hardware interface is self-contained. Once plugged in, the LCD display activates immediately. This screen provides real-time voltage readings with +/-0.01V accuracy. You can also view the Power Good (PG) signal status. This setup allows you to verify that each circuit is functioning correctly without complex configurations. The tool is designed for quick detection. You can use it to identify output issues rapidly. If any voltage or PG value exceeds normal limits, the device alerts you. The buzzer sounds a warning signal. The corresponding value on the LCD flashes to highlight the problem. This feature helps you pinpoint faulty rails easily. The tester is useful for checking the health of computer power units. It is particularly helpful for power sales personnel or companies that need to verify multiple units. The compact design makes it easy to handle in tight spaces. You can carry it in a tool bag or keep it on your workbench. The black finish helps it blend into standard workspace environments. The device provides intuitive and accurate data. You do not need to interpret complex codes. The display shows clear numerical values. This simplicity reduces the chance of misreading results. The tester serves as a reliable helper for PC diagnostics. It eliminates the guesswork involved in checking power supply outputs. You can trust the data shown on the screen to determine if a unit is safe to use.
Before you buy this tester
You should verify that your power supply uses standard ATX, BTX, ITX, or TFX connectors. The BUBUCAM WU0037 supports these common form factors. Ensure your PSU has the necessary pins for the 20/24 pin ATX and 4/6/8 pin connectors. This device tests voltage and the Power Good signal. It does not measure load capacity or efficiency. You may need a separate load tester for deep diagnostics. Keep the unit dry and clean to maintain the LCD clarity. Store it in a static-safe bag. This tool fits well alongside other PC Power Supplies & UPS guides as a quick health check. It helps you identify faulty rails before installing components. Use it to confirm a replacement PSU works correctly. It is a practical addition to your repair kit.
Check before you buy
- Confirm your PSU uses ATX, BTX, ITX, or TFX connectors.
- Check that your unit has 20/24 pin ATX and 4/6/8 pin sockets.
- Ensure you have a static-safe storage bag for the device.
- Verify you need only voltage checks, not full load testing.
