CaseBuy EZ power supply
tester III
Troubleshooting computers can sometimes be a tiresome task. Having
some tools around to help is always welcome here at the Club.
Casebuy has sent over there latest edition of their power supply tester.
Knowing if you power supply is bad or going bad can save a lot of time
while troubleshooting. Sometimes a faulty power supply can cause
all kinds of strange problems and most of the time it's the last thing
we look at. Maybe it's because it's not an easy component to swap
into another computer to test. With the EZ power supply tester we
can test a power supply in just a few minutes. Let's take a look
at it.

The tester is very
small but feels like a quality device. The enclosure is made
from aluminum and seems durable. The tester requires the main
power connector and an auxiliary power connector to be plugged into
the tester before it will work.
The LCD is beautiful.
It's large and the colors make reading it very easy. The LCD
displays the readings for the power supply. If you are testing
a Molex, SATA, Floppy, or PCI-E cable, green lights on the tester
will tell you if they are good or bad.

There are several ports
on the tester all you have to do is decide which one you want to
test. This is the Molex test. Notice the green lights in
the picture indicating that the 12V and 5V in the molex connector
are good.

The floppy test is the
same as the molex, but don't forget that the SATA connector has a
3.3V light too.
Using and
Testing
Using the
power supply tester is very easy. All you have to do is plug the
connectors in and look at the screen. Just remember to only plug
in one cable to test at a time. For testing, I used the Aerocool
Zero DBA 620W power supply and a multimeter. I wanted to test the
accuracy of the EZ PSU Tester. The Features claim +/- 0.1V.
So we'll see.

As you can see the EZ
power supply tester III was very accurate with my multimeter.
Conclusion
The EZ power supply tester
III is a must have for the computer enthusiasts. It's small,
lightweight and doesn't require its own power source. It has the
ability to test every kind of connector that you can find on a power
supply. The tester is a lot easier to use than a multimeter.
Best of all you don't need to know which wires are the 12V, which ones
are the 3.3V. The tester is just plug and play. It's much
easier than getting the pin-out diagram of a 24-pin connector.
