The P4 connector supplies +12VDC to the CPU. The other options are incorrect because the RAM typically receives +3.3VDC and +5VDC from other connectors such as the ATX and SATA connectors, respectively. The GPU also typically receives +3.3VDC and +5VDC from other connectors. The HDD typically receives +12VDC and +5VDC from other connectors such as the SATA and Molex connectors, respectively.
