Founded in 1997, Coolmax Technology Inc. is a rapidly growing company that has become known for their power supply units among other products. Upon it's initial opening, Coolmax Technology Inc. provided cooling solutions for electrical and industrial applications using AC and DC voltage fans to gain a solid foundation for the company they are today. The company now offers a major product line that includes External enclosures for hard drives, optical drives, power supplies, cables and case mods.

The Coolmax PU-224 LCD Power Supply Tester is intended to provide a simple and easy way to test a possible faulty or non-working computer power supply unit. The PS-224 has a durable aluminum casing with a back-lit LCD that makes diagnosis quick and easy. The unit provides voltage readouts that can indicate a possible over or under-voltage of any given rail as well as an alarm that indicates over-voltage, under-voltage, or no voltage at all.

7.5 The Coolmax PS-224 does exactly what you would expect it to do. Its sole purpose is to test your power supply and to let you know what voltage it actually delivers. It does so well and the backlit display is easy to read and should come in handy when crawling around under your desk to check that PSU of yours. We would have liked to see an 8 pin PCI-E power connector to accommodate the newest generation of PSU. Even though this is a simple gadget, a manual with some information of what readings are within ATX specifications would have been a nice addition. Considering the price tag of just under 30 US Dollars and the potential to take out a lot of guesswork when troubleshooting a PC, the value of the Coolmax PS-224 should not be understated. We would have liked to see the unit priced a bit lower, as similar units from other manufacturers cost up to $9 less around the internet.
