If you are experiencing problems such as power-on, startup failures, or lockups; Spontaneous rebooting or intermittent lockups during normal operation; intermittent parity checks or memory type errors; Hard disk and fan simultaneously fail to spin; Over heating due to fan failure; Small brown-outs that cause system resets; Electric shocks from case or connectors; Slight static discharges that disrupts system operation; Erratic recognition of bus-powered USB devices, is a good indication the power supply is bad.
