If you've replaced the power supply with a known good power supply (I've seen more than one case where the 'new' power supply was defective) there are 2 other things I can think of that may be causing this. First of all, it could be that there's a cooling problem with your CPU. More than likely, if this is the case, the heat sensor on the motherboard that lets the computer know the CPU temperature is faulty. This is fairly rare. My second idea, unfortunately, is the motherboard. There just aren't too many things that cause a computer to turn off that quickly. One good way to make narrow it down to the motherboard is to strip it down to just the CPU and motherboard and power supply. Disconnect all drives and remove all add-on cards (video, sound, NIC, etc.) The goal isn't to get it to boot per se, but to see if it stays on. You should have ONLY the motherboard with the CPU and power supply plugged in. If it DOES stay on, start putting things in one at a time to figure out what's causing the problem. If this doesn't help or you need additional info, let me know and I'll get back to you ASAP! :)
infact i think the power supply be replaced with new one. infact i think the power supply be replaced with new one.
No attempt should be made to repair the power supply. The power supply should be replaced with a power supply of equal or greater wattage.
The power supply that you replaced the old one with might have a louder, faster fan inside. Also, your last power supply could have broke down due to it's fan being shot and it wasn't operating at all.
A computer's (PC's) power supply is a sealed unit and should be replaced as a whole - It is dangerous to try and repair the inside of that sealed unit (that is why it is sealed).
Yes. However you will not be able to see anything as the 12V 4.5A power supply does not come with a screen.
Universal power suppply is power supply that is universal.
No, the SNES power supply will not work for the GameCube. You need the SNES power supply for the SNES, and the GameCube power supply for the GameCube.
flash the bios. Duhh
look at the label on the outside of the power supply
If it is a computer power supply it is the box that gives the computer its power from the outlet.

all about regulated power supply
any power supply with at least 175 watts
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
The Power Supply (PSU) supplies power to the computer. It converts power from the wall (AC power) to DC POWER, which is the type of power computers use.
A PSU (Power Supply Unit) converts the power received from the wall outlet to the power power needed to supply power to the mother board and all other components within the PC.
Try the simple things first: Flash the BIOS
power supply is a device that supplies electric power to electrical load
DC Power is Direct Current Power Supply.

To keep the power supply cool. If there were no fan the power supply would overheat and fail.
A power supply is a device that adjusts power to the right wattage and distributes the power with in the computer.
Advantage of regulated power supply.
