    Not Worth the Money

    Very disappointed with this device. It is basically useless if you already have a basic multimeter for measuring voltages. I expected it to provide additional testing capabilities, such as measuring output power, but it only measures voltage.This is not really a tester - it is just an expensive voltmeter with a misleading purpose. For the price, I expected much more functionality and better value.

    PSU tester that gives a genuinely clear read on where a supply stands

    This turned out better than I expected going in.

A short press of the button cycles through the individual channels one at a time if you want to isolate a specific reading instead of parsing all of them together. Once you've cycled through every

    Excellent Tool for Diagnosing PSU Issues

    This is one of those tools you probably will not use every day, but if you build, repair, or troubleshoot PCs, you will be very glad to have it when something goes wrong. It gives you considerably more useful information than simply figuring out whether a power supply turns on.The color display is clear and makes the voltage readings easy to check at a glance. Being able to see the 12V, 5V, 3.3V, standby voltage, and power good timing gives you a much better idea of what the power supply is actually doing. I especially like the audible warning and red display when it detects a problem since th
