I am looking to buy a board to replace my broken mATX board. But that board has a 8 pin ATX 12V power connector for the CPU instead of the regular 4 pin one. Unfortunately the new PSU that I bought a month ago doesn't have the 8 pin connector, only 4 pin. Can I still use the 4 pin and plug into the 8 pin connector? Will it power the CPU properly with stability? Can I still overclock? Or is there a convertor like 4 pin to 8 pin? Please help.
