[SOLVED] Some mini-ITX motherboards do not have 24-pin (or 20-pin) power connector ?

[imyangdonguk]

I've searched and found that some of mini-itx motherboards don't have 24-pin (or 20-pin) and only have ATX 12V 4-pin power connector.

My question is which connector can be used from common ATX power supplies.
I hope 4-pin (maybe 4+4) connector used for CPU might work.

That motherboard is a special one that uses a laptop CPU. Yes the 4 pin CPU power plug would be used on it.

I am partly-succesfully using 2 pins of the 4+4 CPU connector to power a Gigabyte GA-H81TN with a Corsair SF450 PSU with a jumper wire on the green pin (PS_ON)to GND. But it does not work flawless. As soon as i turn on the PSU with the PSU on/off button, the GPU fan and HDD's will start spinning at max speed until i hit the enclosure on/off/reset button. After the motherboard starts running everything is fine. Windows reboot is also not working. When restarting, the pc will hang in the turn off/on cycle, reboot does work when only the motherboard is connected to the PSU. I am considering powering the GPU fans from a motherboard header and removing the seperate HDD's so that everything (except the GPU 6pin) is powered from the motherboard.
