Product Description： Support P4 4Pin, 8Pin interface 4 Pin power connector, supports standard SATA interface Support Molex / Xeco Power Interface Support 20Pin, 24Pin ATX power supply Supports SATA power Support for PCI-E graphics card power connector 6Pin Support floppy drive power connector Test voltage + 3. 3V, -12V, + 5VSB, + 12V1, + 12V2, + 5V Features: PG automatic alarm, LCD display case every volts Method of operation: a. the power 24PIN and P4, P6 or P8 plug into a power tester corresponding position. b. Turn on the power, while the "bit" sound twice startup sound, if the value of each group were not flashing, it means the input power supply is normal. c. If a circuit voltage signal is not detected (eg 20PIN 20PIN connector jack) or the detected voltage exceeds the normal range, the buzzer will emit a long time, "Didi" warning sound, and the corresponding voltage value or PG Displays the status blinks, it indicates that this is a failed power supply! Specifications: Input voltage: 20 / 40PIN (ATX power supply) Voltage detection: + 12V -12V + 5V -5V + 3. 3V 5VSB 12VPG Ports: Floppy HDD COROM SATA 4pin (P4) 8pin (Dual-CPU) 6pin (PCI-E) Any supply voltage or PG problems will alarm and display the voltage value, solve the first generation of a set of low voltage tester to test out the problem! Very convenient, this is the best power detection tool on the market ! ! ! Package Includes: 1 x Kingwin DIGITAL LCD POWER SUPPLY TESTER
