using an Mini-ITX Power supply with an ATX Mainboard

[Steve-Kai Vyska]

Hi,

I have an AMD K6/2 Mainboard and try to connect it to an Mini-ITX Power
Supply having 150W

When I start the Computer it powers up but turns off 3 sec after start.

Can someone tell me why? Or is it not possible to connect the ITX
Power-supplay to an normal ATX Mainboard.

Thanks

Steve

You cannot mix ITX and ATX form factors.
