Coolmax PS228 Power Supply Tester

ps228Last week we reviewed a device that should be in the toolbox of every computer repairman, network tech and enthusiast: the Vantec universal adapter. Truly a bit of hardware to make life much easier. Today, we will be reviewing another product in the same class. Let me introduce you to the PS228 from Coolmax. It has a nice blue backlit LCD listing all the voltage readings for connections on a computer power supply. Furthermore, it sounds an alarm to let you know if anything is wrong.



We definitely love the Coolmax PS228 around the lab. It was ideal for doing quick tests on incoming power supplies. Getting a visual readout on the different voltage rails rather than some green lights indicating if a power is in good working order is great. No more guessing if the rails are within specs. The LCD display is also very easy to read to the point no real tech knowledge is necessary. For under $20, the usefulness goes way beyond monetary value.
