Thermaltake Dr Power II PSU Tester Review @ Ninjalane
 

It doesn't happen very often but when a power supply fails you often unaware that anything is wrong until it is too late. This can be especially troubling when you are left troubleshooting random lockups or system crashes and can't tell what the problem is. For issues like this it is sometimes best to "chase the power" and make sure your power supply is operating correctly.
