Just Bought The Mach 4 tried to test it with current power supply
I bought a new XFX Mach4 Socket A/462 ATX Motherboard for my
APEVIA X-Dreamer II ATXB4KLW-BK Black Steel ATX Mid Tower Computer Case 420W Power Supply Case that was made to work with my now dead
Shuttle AN35N-Ultra 462(A) NVIDIA nForce2 Ultra 400 ATX AMD Motherboard. I went to my local computer repair shop to see if the power supply was functioning and it was, but now when i plug the power supply into this new motherboard the power supply doesn't turn on but the mother boards led light stays on showing that power is going to it. What do you think the problem is?
Re: Just Bought The Mach 4 tried to test it with current...
Hi, one quick thing you can check is to see if the cable running from the power switch is plugged onto the right pins on the motherboard, it will most likerly say (pwr btn) next to the pins or something like that, it may also need to be a certain way round.Let me know what the outcome is if no good we can try something else. hope this has helped. Thanks

As long as it is an ATX compatible power supply increasing the available wattage is not an issue, only meeting MIMIMUM power requirements
You can go to a 500, or even a 750 as long as it has the correct motherboard connections
check yourt power supply waltage and earthing.
also try toi start computer with only mother bord and smps in out of the cpu cabinet.
then check .also disconnect har ddisk and then checxk u get disaply from mothe rbnord.
Please CLICK HERE for more info on your power supply. My guess is that your power supply is dead. If the fan doesn't spin it may be that the fan died first and the PSU overheated.
Now, if you are fortunate nothing else got damaged. You can remove the
PSU (the mounting screws are on the back of the case, there should be
four) and buy a new one at your friendly local computer parts store.
Get one rated for at least as much power as the old one. We can give
you a hand on this if you tell us what the lable on the side of the PSU
I should caution you that there is a chance that when the PSU went it damaged other parts of your system.
The ATX power supply needs to have pin16(PS_On#) to be connected to COM for it to work.
When you press the power switch on the front panel of the computer, you are essentially making this connection.
Check that the cable from the power supply to the motherboard is making good connection.
You can verify operation of the power supply by shorting Pin16 to pin17 on the powersupply output, with a paper clip. Pin16 is usually a green wire and 17 is black.
Hope this helps.
I assume you have tried with only one stick of ram individually at a time if you are using two to check it's not the ram as one faulty can cause the system to stop.
Also assuming you bought the ram from the same place and is compatible with the board.
Sometimes people also forget that the processor in some cases has to be powered by the 4 pin plug from the PSU and not just from the ZIF socket that older processors use to power up, so double check the manual.
The other main common cause of the this problem is when you are putting together all the hardware onto the board, if you don't protect it underneath it may have overflexed the board and shorted or damaged the circuitry or the bios chip.
That's not to say that the motherboard was'nt faulty in the first place.
