Q: May I use the power supply without +12V power (4 pins) connector for ASRock Intel platform Motherboards? (2003/6/13) A: ASRock has its own design to omit the Intel specified 4-pin connector. All needed power for motherboard can be supplied from 20-pin ATX connector. So ASRock P4 platform motherboards is able to support some power supplies without +12V 4-pin connector.
