Features 1、【Simple and Intuitive Diagnosis】: The tester is designed to quickly and accurately determine the output performance and design stability of the computers/u0027 powersupply, the user only needs to connect the ATX connector of the unloaded powersupply to the tester, and you can intuitively understand the voltage of the various circuits through the LCD screen and the PG value, easy to identify whether the powersupply is working properly, greatly simplifies the traditional multimeter testing process, easy to operate for ordinary users. 2、【Comprehensive Compatibility】: Comprehensively support ATX, BTX, ITX, TFX, and other specifications of power supplies, equipped with Floppy, HDD, COROM, 4pin (P4), 8pin (Dual-CPU), 6pin (PCI-E) and other connecting ports, to ensure comprehensive testing of all types of powersupply interfaces, to meet the diverse computers system configuration. The system is designed to meet the needs of diverse computers system configurations. 3、【Instant Failure Alarm】: When detecting abnormal power output, the tester will prompt the user through the LCD screen flashing and alarm, timely detection and localization of the problem, which helps to prevents hardware damage and ensure the stable operation of the computers system. Simplify the testing process and improve diagnostic efficiency. 4、【User-friendly Design】: The power tester has a simple and easy-to-understand operation interface, which is easy to use even for non-professionals. In addition, users are reminded to avoids hot-swap operations to ensure the accuracy of the test data. 5、【Lightweight and Portable Design】: With a plastics casing, this product is lightweight and portable, convenient for users to test power supplies on different occasions or environments to enhance work efficiency. Specification This tester is designed to measure the stability of the voltage output of a powersupply. By simply connecting the ATX connector of the powersupply, you can easily and intuitively determine whether the output of the powersupply is normal or not. The tester can be used to test ATX, BTX, ITX, and TFX computers' power supplies, and comes with an LCD display to show each group of voltage and PG value, making it a fast testing instrument.
