Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Power Supply Testers
For a low cost device to check out computer power supplies this is a great tool. I went through several used supplies I had pulled and checked them with this tester and found one was unstable (voltages jumping around) while the others were fine. Being able to see all voltages at the same time is a nice time saver and a whole lot easier than poking the leads one by one with a meter.

Nice device but the quality of build isn't very good, as its black case broke on my first try to connect it with a power unit of a pc.

I used it a couple of times to test voltage measurements of a couple of power supplies. It works once the power supply has an available power source.
