Design and build details
According to the listing, the Ejoyous LCD Power Supply Tester is built for direct connection to the ATX connector of a power supply. This design allows you to easily and intuitively know whether the output of each power supply is normal. The unit features an LCD display that shows various voltage and PG values. This screen lets you quickly detect the performance of your computer power supply without needing additional monitors or software. The device supports multiple form factors, including ATX, ITX, BTX, and TFX. This versatility means you can use it with a wide range of computer cases and power units. You do not need to worry about compatibility issues when testing different builds.
The tester also measures output wires for P4, P6, P8, SATA, and IDE connectors. External DIE, SATA, P6, and P8 connections are indicated by light displays. However, the LCD voltage display only appears when connecting to the 24-pin or 20-pin interface. This distinction helps you understand what information is available for each connection type. When parameters exceed normal values, the buzzer sounds a warning, and the corresponding value flashes on the screen. This automatic alarm system ensures you are immediately aware of potential issues. The device supports various interfaces, including SATA, 4-pin, 8-pin, PCI-E graphics card 6-pin, floppy drive, and Xeco power interfaces. This comprehensive support makes it a practical tool for technicians who work with diverse hardware configurations. The build focuses on functionality, providing clear visual and audio feedback for accurate diagnostics.
Setup and daily operation guide
Setting up the Ejoyous LCD Power Supply Tester is straightforward. You simply connect the device to the ATX connector of your power supply. This direct connection allows you to quickly determine if the output is normal. The unit supports multiple form factors, including ATX, ITX, BTX, and TFX. This versatility means you can use it with a wide range of computer power supplies without needing adapters for the main board connection.
Once connected, the LCD display becomes your primary interface. It shows various voltage levels and Power Good (PG) values. You get immediate visual feedback on the health of your power supply. The screen displays voltage for each rail, giving you a clear picture of performance. If any parameter exceeds the normal value, the buzzer sounds a warning. The corresponding value on the LCD will also flash to alert you. This automatic alarm system helps you catch issues without constant monitoring.
For peripheral connections, the tester measures output wires for P4, P6, P8, SATA, and IDE interfaces. External connectors like SATA, P6, and P8 use light displays rather than the LCD screen. You only get voltage readings on the LCD when connected to the 20-pin or 24-pin ATX interface. The device also supports PCI-E graphics card 6-pin interfaces and floppy drive connectors. This comprehensive coverage allows you to check nearly all standard power delivery points. Daily use involves plugging in, reading the screen, and noting any alarms. It is a practical tool for verifying PSU stability during builds or repairs.
Before You Buy This Tester
Before purchasing the Ejoyous LCD Power Supply Tester, verify your power supply form factor. It supports ATX, ITX, BTX, and TFX units. You must ensure your PSU has a standard 20-pin or 24-pin main connector. The device connects directly to this interface for primary voltage readings. Note that SATA, P4, P6, P8, and floppy connectors only show light indicators. They do not display voltage on the LCD screen. You will need these additional cables if you want to check peripheral power rails. Keep the unit clean and store it in a dry place. This tester fits well alongside other PSU options by offering a quick, visual diagnostic tool. It helps you confirm basic output stability without complex equipment. If you frequently swap power supplies or troubleshoot builds, this simple device saves time. It provides immediate feedback via the screen and buzzer alerts. Ensure you understand the difference between the LCD voltage display and the simple LED indicators for other connectors. This clarity helps you avoid confusion during testing.
