CoolMax Deluxe 20+4-Pin ATX Power Supply Tester

This CoolMax Power Supply Tester allows fast and easy tests for your power supply! You can use this device if you want to test an ATX power supply, but you don't have a motherboard to plug it into. Or if you suspect the power supply may be bad, and don't want to risk frying your motherboard just to test the power supply! Just plug it into the power supply's 24-pin ATX connector, and it will turn the power supply on. The LED will light up and you will hear a sound if the power supply tests well. It can also be used to test the large 4-pin (HDD) Molex, floppy, SATA, 12V (P4), and Power HDD connectors to check if it passes or fails!
