Introduction:
Several months back we looked at the EZ Power Supply Tester from Casebuy. This proved to be a handy little product for making quick evaluations on a power supply. The output voltages are shown by separate LED's which would light up for each rail. At the time that tester was an excellent product but it had a few limitations, such as, it didn't support 24pin ATX connectors and SATA just to name a few. Casebuy has now come out with the EZ Power Supply Tester 2 which now supports all the major plugs you would find on any of today's power supplies.

Features:
The power supply tester is nice and pocket sized, measuring in at 89x63.7x17.5mm. The outside casing is an anodized blue colour on the new revision of the tester, the old one was just a brushed aluminum colour.

The top of the power supply tester has the instructions written on it that one would follow to properly test a power supply as well as the Casebuy logo and EZ Power Supply Tester 2 logo written on the bottom half of the top. At each side there are LED's which correspond to the rails and connectors being tested. From the top to the bottom for the ATX motherboard plug there is +3.3V, -12V, PG, +5VSB, +12V, -5V and +5V. On the right side the 3 LED's which correspond with all the other plugs on the device are +12V, +3.3V and +5V.

The bottom of the power supply tester simply has two barcodes and a "warranty void if removed" sticker.

On the far side of the tester there is a connector for a SATA plug and on the edge closest to you there is the molex plug. On the right side there is the connector for the 24 pin ATX motherboard plug. On the left side there is a hybrid connector for both 8/4 pin 12V connectors, a 6 pin PCI Express connector and finally a floppy connector.

Testing:
To test the Power Supply Tester 2 I took a spare power supply off my shelf which had all the connections featured on the tester and proceeded to test it. When one wants to test a power supply with the tester you plug the ATX motherboard plug into the connector for it on the tester and power on the supply. If you hear one beep and the LED's light up then that part of the power supply tests OK. While that is plugged in, you then turn off the power supply and test each of the other connectors one at a time in the appropriate plug. Remember to turn off the power supply while you are plugging and unplugging each connector. One beep is the code for a passing supply but if you hear more than one beep then something is wrong!

You'll should also be aware that written on the box and website is a note that the power supply should not be left on for extended amounts of time as the tester could heat up and cause damage to the power supply.

Another handy use is that when the ATX connector is plugged into the tester and the power supply turned on the tester essentially "hotwire" the power supply on so it can check for the voltages. If you only plug in the ATX plug and were to plug a CD ROM drive into a molex connector on the power supply for a quick test then when you flick the power supply on it is fully operational! I have used the old tester and now this one numerous times to do tests on hardware that I think may be faulty. That way I don't need to put it into my PC and risk possible damage. However, remember not to leave the power supply on for long amounts of time as stated above. If you want to use it for something like that alongside testing the integrity of power supplies, then make your other tests brief!

In the two images below I have shown all the plug types that are supported plugged into the tester. All the cables were plugged in at once for photo reasons only. DO NOT attempt to plug in all the cables at once and actually power on the supply.

Conclusion:
Overall, I was extremely pleased with the EZ Power Supply Tester 2 from Casebuy. This is definitely a must have tool for anyone who works with PCs to test power supplies before putting them into a PC. A bad power supply could mean damage to system components if the voltages are not correct, and don't assume that a brand new power supply will operate correctly. I have seen brand new power supplies with incorrect and even damaging voltages. This tester is also a must have item for any home user who likes to tinker around with computers.

Pros:
Supports all major power supply connections!
Allows you to start up a power supply without being in a PC to quickly test hardware
Small and compact

Cons:
None!

Rating: 10/10
