ATX Computer Power Supply Tester
Obtain quick verification of proper operation of ATX style computer power supplies. Simply connect the Tenma computer power supply tester to the ATX supply's 20 pin connector, and slide the testers rocker switch to the ON position. The tester applies the proper current load and simulates the ON command from the motherboard, and provides LED verification of proper operation. Further verification can be obtained by measuring the pin voltage using a standard DMM such as our Tenma model 72-7770 (not included).
