No power supply or what?

When i purchase the system, I found that the system cannot boot up the bios.
I do alot of check and i bring down to repair shop to check, there said is Motherboard spoilt.
i did buy another new motherboard, the problem still the same.


But at last, i can boot up and run the system, The problem is i had 5 Old PC, only 1 of the power supply can boot up this 2 motherboard. The rest of the power supply only can let the fan run and motherboard got LED light up.

So what the reason? Even my New power supply cannot boot. ALL my old sys is AMD. So does this new motherboard. If the rest of my power supply is not working, then it cannot be, because i still can run my old PC. If said incompatiable, then 5 old PC is just not more 2 year old, cannot be, + 1 New . So total i got 6 Power supply to test out 2 motherboard. Only 1 Supply can run smoothly.

Funny right? Best part, i bring down again to show them, there try their some of their own Power supply, also cannot. So what the problem with this 2 motherboard? ASUS and Gigabyte. LOL

 

Is this a newer style motherboard that requires a 24-pin power supply and your old power supplies are 20-pin? If so some boards can be damaged by not using the correct power supply. What is the motherboard make and model number?

 

u right, old and new power supply is all 20 pin. my motherboard is 24 pin
But the one can make the motherboard boot up also 20 pin
