I am building my new PC. I am really a newbie at this.
Currently I have SIEMENS D1107 motherboard. I want to replace it with HP P4SD motherboard.
But there is a one problem. The new motherboard has 4 pin 12v connector but my PSU doesn`t have it.
Is this connector necessary, will my motherboard work without it and if it do work, what problems are expected?
I have tried to start system without that wire, but power led does not turning on, and PC shutdowns itself. :)
I don`t need to buy a new PSU. I can buy an adapter like this one:
