Coolmax 14909 PS-224 LCD 24-Pin ATX Power Supply Tester

 (27 customer reviews)

Great device for testing power supplies with many different types of connections. This is of the modern type that allows for SATA connectors to be used for testing of electrical current coming from the power supply. Must already be knowledgeable of power supplies and their currents to know how to use. This is a great device that substitutes for the multimeter for those who find it too complex.

My original power supply tester was only a "power present" tester with simply an LED and an on-off switch. That proved to be very inadequate for power supply testing. This tester by Coolmax will accurately test all power outputs from any standard power supply and lets you know if they are within usable range or not. This item has more than paid for itself by eliminating misdiagnoses of power supplies and also is light, small and easily added to any portable tech kit.

Summary:
This is a nice product, but the documentation could be better.... Note, I was shipped a PS-228 instead of the PS-224, which is just fine with me however if you are reading this review, be aware my comments address the PS-228 and not the PS-224 since I was shipped a PS-228.

The Good:
The physical build quality on this unit is very good - it's built for a rough shop work and the aluminum case feels and looks like it will take the abuse of constant use for years to come. The display is very nice and easy to read backlit showing all the details you need; this is important for me since it seems like I'm always testing under a desk or somewhere dimly lit. Some other reviewers mentioned the 24 pin jack on the PS-224 was not well made and there was great difficulty in connecting the power supply - this must have been isolated to the PS-224, the PS-228 connects easily and correctly every time across several makes of power supplies I've tried.
