["brand new and high quality\nColor:Black\nVoltage source : 20/24 pin ( ATX - connector )\nVoltage test : +12V , -12V , +5V , -5V , +3.3V , +5V Stand by (SB) 12V power Good ( PG )\nConnectors : Floppy, HDD , CDROM , SATA , 4pin ( P4 ) , 8pin ( Dual-CPU ) , 6pin ( PCI-Express ) Product Introduction:\nThe SD power supply tester is a robust voltage, tester for PC-power supply, ATX . BTX and ITX compliant, power supplies can be tested. LCD`s indicate the status of voltage .The PC / SPS is suitable for the ambitious hobby user , as well as for a quick functional check in for specialized trade. The methods of operation:\nPlug power supply 24 PIN and P4 , P6 or P8 into the corresponding jack of the power test suite.\nPower on the supply of power, will hear \"DuDu\" ring , if no flicker then the power supply output voltage is normal.\nIf a certain voltage signal was not detected, or the detected voltage value over the normal, will issue a \"DuDu\" long buzzer ; if the corresponding voltage value or PG flicker too, then the power is failed.\nSize:12cm x 6cm/4.72\" x 2.36\"\nQuantity:1Pc\nAs different computers display colors differently, the color of the actual item may vary slightly from the above images, thanks for your understanding."]
