I hope this thread is still active, as you gave me some good leads before. But I think I screwed up & ordered a wrong PSU tester. The Power Supplys I want to test are for the DELL Dimension Desktops 4400, 4500. Both have a 20 Pin + 4 Pin Connectors to the System Board. The PSU tester I ordered from Geeks.com is DG's Power Supply Tester for power supply ATX, BTX, and ITX Compliant Power Supplys. Description says: 1.8 LCD 20+4 Pin PSU tester w/8/6/4 Pin Connectors. The receptacle on the tester is 24 Pin, and is much larger than the mother board connector, so of course, nothing fits ! Where did I go wrong, and what should I order ?
Your help (and Patience) is greatly appreciated.
