The LCD displays various parameters such as output voltage and PG. When each parameter exceeds the normal value, the buzzer will sound a warning sound, and the corresponding value will flash. PG automatically alarms, and the LCD displays the voltage of each volt.The LCD power tester is a powerful power test device. This power tester only needs to be connected to the ATX connector of the power supply to easily and intuitively know whether the output of each power supply is normal. It can detect ATX, BTX, ITX, TFX computer power supply, and can display various voltage and PG values in LCD screen to quickly detect the performance of computer power supply.Features:LCD liquid crystal display, the output voltage is clear at a glance.If there is any defect, the buzzer will automatically alarm.It can also measure the output wire P4/P6/P8/SATA/IDE, and the external DIE/SATA/P6/P8 is the light display, there is no LCD voltage. There is LCD voltage display only when connecting to the 24pin or 20pin.Small and practical power tester. Now the number of power output groups is increasing. As long as one of them has problem, the hardware of the computer system may work abnormally or even burn out. To measure whether the output voltage output of the power supply is stable, the player usually uses a multimeter. But for the average user is still a little troublesome.We have developed a portable computer power tester for the power supply market that cannot judge the quality of the power supply. It has LCD intuitive and accurate display voltage (+/-0.01V), automatic fault alarm, complete test interface, small and beautiful appearance, and more test functions. It is your best choice and reliable helper to quickly detect PC power.This power tester only needs to be connected to the power supply ATX connector to easily and intuitively know whether the output of each power supply is normal. Power Star Power Tester is a powerful power test device that can detect ATX, BTX, ITX, TFX computer power supplies, and can display various groups of voltage and PG values in the LCD screen, and quickly detect computer power supply to facilitate the instrument.Specifications:Support 20Pin, 24Pin ATX interfaceSupport SATA interfaceSupport 4Pin, 8Pin interfaceSupport PCI-E graphics card 6Pin interfaceSupport floppy drive interfaceSupport molex/Xeco power interfaceSupport standard 4Pin power interface, STAT hard disk interfaceTest voltage: +3.3V, -12V, +5VSB, +12V1, +12V2, +5V and PG time valueMaterial: plastic shellPackage List:1 * Tester
