My computer crashed and did not reflect the press restart button, then directly related to the power supply! Will this do it?

Experts answer: Make sure the hard disk does not work, power off, press and hold the chassis power switch for 5 seconds without letting go on the line, do not directly pull the plug or power switch off delay line board.
