Who it fits
Good fit for
This tool suits PC builders, technicians, and enthusiasts who frequently test power supplies. It is ideal for anyone who wants to avoid the hassle of using a multimeter for routine checks. If you work with various form factors like ATX, ITX, or BTX, this compact tester covers them all. The visual feedback and audible alarm make it a convenient choice for quickly verifying that a power supply is delivering stable voltages before installing it in a system.
Who should skip it
You should look elsewhere if you need to measure external PCIe, SATA, or IDE cables. The data indicates that while the tester can connect to these wires, it only shows light indicators for them. You will not get the precise LCD voltage readings for these specific connectors. The detailed digital display is reserved exclusively for the 20-pin or 24-pin ATX connections. If your workflow relies heavily on testing individual peripheral power cables with voltage precision, this device has limitations.
Verdict: It is a straightforward, spec-driven tool for checking main power output stability. The LCD and buzzer provide clear, immediate feedback for standard ATX connections.

The compact form factor ensures it does not take up much space on your workbench.
The device features an LCD display that provides intuitive and accurate voltage readings. The screen shows values with an accuracy of plus or minus 0.01 volts. This allows you to quickly verify the stability of each power rail. The listing notes that the display is clear and easy to read during testing. You get immediate visual feedback on the health of your power supply.
A buzzer alarm activates when test values fall outside the normal range. This automatic fault alarm helps you identify issues without constant monitoring. The tester connects to ATX, ITX, BTX, and other power connectors. It also supports P4, P6, P8, and SATA external connectors. However, the LCD voltage display only works when connected to the 20-pin or 24-pin main connector. Other connectors rely on light indicators for status. This design choice keeps the device simple and focused on primary power diagnostics.
Setup and everyday use guide
Setting up this ASHATA LCD Power Supply Tester involves a straightforward connection process. You simply plug the tester into the ATX connector of the power supply you wish to evaluate. This single step activates the device, allowing it to begin monitoring the output immediately. The unit is designed to work with a variety of form factors, including ATX, ITX, BTX, and TFX power supplies. This broad compatibility means you do not need multiple tools for different system builds.
During daily use, the LCD display provides intuitive and accurate voltage readings. The screen shows values with an accuracy of plus or minus 0.01 volts. This level of precision helps you verify that each rail is delivering stable power. If the test value falls within the normal range, the tester issues a buzzer alarm. This feature allows you to quickly know the status without constantly staring at the screen. The display also shows PG (Power Good) values, giving you a complete picture of the power supply's health.
For additional connectors, the tester can measure output wires such as P4, P6, P8, SATA, and IDE. However, note that the LCD voltage display only appears when connected to the 20-pin or 24-pin main connector. External connectors like SATA or P8 will only show light indicators, not voltage readings on the screen. This distinction is important for accurate diagnostics. The small size and light weight of 2.82 ounces make it easy to store and carry. You can use it to quickly detect performance issues or verify stability before installing components in your system.
Before you buy this tester
You should verify that your power supply supports the connectors this unit checks. The listing states it works with ATX, ITX, BTX, and TFX standards. It also handles PCIe, SATA, and HD interfaces. Note that the LCD voltage display only activates when you connect the main 24-pin or 20-pin ATX plug. Other connectors like P4, P6, P8, or external SATA show only light indicators without voltage numbers. Keep the device clean and dry to maintain accuracy. Store it in a static-safe bag when not in use. This tool fits well alongside other PC power supplies and UPS units in your setup. It offers a quick visual check that complements deeper diagnostics. You do not need extra software or drivers. Just plug it in and read the screen. It is a simple, practical addition for anyone who values clear, immediate feedback on power rail stability without complex equipment.
Check before you buy
- Confirm your PSU supports ATX, ITX, or BTX standards.
- Check if you need LCD voltage for main connectors only.
- Ensure you have the correct 20-pin or 24-pin plug.
- Verify compatibility with SATA and PCIe connector types.
