YNS-001 ATX Measuring Checker Diagnostic Tool Digital Display Computer Power Supply Tester

1. Nowadays, there are more and more power output groups. As long as one of them has a problem, the hardware of the computer system may not work properly or even burn out related accessories
2. This power supply tester only needs to connect the ATX connector of the power supply to simply and intuitively know whether the output of each power supply is normal
3. It can detect ATX, BTX, ITX, TFX computer power supplies, and can display each group of voltage and PG value on LCD. It is a convenient instrument for quickly detecting computer power supplies

Operation method:
1. Insert the unloaded 20Pin or 24Pin plug of the power supply into the corresponding position of the power supply tester. Turn on the power supply, and "beep" two startup sounds will sound at the same time. If the values ??of each group do not flash and alarm, it means that the output power of this power supply is normal. If the corresponding voltage or PG value is displayed as a flashing alarm state, it means that this power supply is a faulty power supply! The test related values ??can refer to the following chart
(Tip: If you only plug in the 20Pin or 24Pin interface tester, and the screen (+12V2) alarms and displays LL, the LL displayed here is for testing 4P or 6P/8P. If it is not plugged in, you can ignore it. Or just plug in one of the groups. Please make sure that 4P must be plugged in the 4P position! Dont plug it wrong!)
2. Other large 4P (HDD interface), small 4P (floppy drive interface), 4P/8P (CPU interface), 6P (graphics card interface), SATA interface, these interfaces are only plugged in when they need to be tested. If not tested, they can be left unplugged
3. Plug in the large 4P (HDD interface), small 4P (floppy drive interface) tester, the +12V and +5V display lights on the left (if the lights are not on, it means that this group of lines is faulty.)
4. Plug in the 4P/8P (CPU interface), 6P (graphics card interface) tester, and the screen (+12V2) displays the test voltage (if there is a fault, it will flash and alarm)
5. Plug in the SATA interface tester, and the +12V, +5V, and +3.3V indicators on the left will light up (If the indicator light is off, it means that this group of circuits is faulty. Some manufacturers power supply SATA interfaces do not have +3.3V voltage output.)

Specifications:
1. Voltage input: 20/40PIN (ATX power supply)
2. Voltage detection: +12V -12V +5V +3.3V 5VSB 12VPG
3. Connection port: Floppy HDD COROM SATA 4pin(P4) 8pin(Dual-CPU) 6pin(PCI-E)

Note:
1. If the +3.3V indicator light does not light up when the SATA interface tester is plugged in, it is because the power supply SATA interface on the market now has 4 or 5 wires! First, confirm whether your power supply SATA interface has 4 or 5 wires. If it has 4 wires, there is no +3.3V output. Only 5 wires have +3.3V output.
2. Try not to hot-plug when using! If hot-plugging is performed, the test data may have some errors.
