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.
