Power supply out of system does not power up. is it dead?
No, your power supply is not necessarily dead. Power supplies require a "power good" signal back from the motherboard before they will turn on. In order to test a power supply that has been removed from the computer, you need a PV power supply tester. Without one, you will either have to take you power supply to a PC technician and have him test it or install a known good power supply in your computer.
