Bench testing a power supply is now simple and comprehensive with Ultra's newest power supply tester. The newest version of this tester is easier to use than ever! Accepting either 20-pin or 24-pin ATX connectors and either 4-pin or 8-pin CPU power connectors, there are test ports for floppy connectors, drive connectors, even SATA and PCI-e! An audible beep tells you if your power supply is powered up and a green LED lights up for each live rail of the power supply. A must for any do-it-yourself PC builder.
