Description:The Computer PC Power Supply Tester is a helpful detection tool for your computer power supplies, designed for multiple models and connectors, with a clear LCD screen, automatic buzzer alarm, accurate real-time status. It's durable to use for long service life.Specification:1. Support 20Pin, 24Pin ATX interface2. Support SA-TA interface3. Support 4Pin, 8Pin interface4. Support PCI-E graphics card 6Pin interface5. Support floppy drive interface 6. Support ATE hard drive interface7. Test voltage has +3.3V, -12V, +5VSB, +12V1, +12V2, +5V and PG time valueOperation Methods:A. Insert the power supply 20PIN or 24PIN and P4, P6, or P8 plug into the corresponding position of the power supply tester. (If you plug in the 20PIN or 24PIN interface tester to alarm and display LL, you need to plug in 4P! Please make sure that the 4P must be plugged in the 4P position!)B. Turn on the power, and there will be two startup sounds at the same time. If the values of each group are not flashing, it means that the power input is normal.C. If the voltage signal of a certain circuit is not detected (such as 20PIN or 24PIN connector) or the detected voltage exceeds the normal range, the buzzer will emit a "didi" warning sound for a long time, and the corresponding voltage or PG value will be displayed If the status is flashing, it means that the power supply is a faulty power supply!Parameters:Name: LCD Computer PC Power Supply TesterMaterial: Aluminum alloy, ABSSize: about 126x64x18.5mm /4.96*2.52*0.73inProduct Weight: 120 gramsVoltage Input: 20/40PIN (ATX power supply)Voltage Detection: +12V -12V +5V -5V +3.3V 5VSB 12VPGConnection Port: Floppy HDD COROM SA-TA 4pin (P4) 8pin (Dual-CPU) 6pin (PCI-E)Packing List:1*Computer PC Power Supply TesterNote:Due to the lighting effects and shooting angles, there is a color difference in the product, please understand.Due to manual measurement, there is a tolerance in the product size.
