My PC's HDD is a Western Digital Caviar Green WD20EZRX 2TB 3.5" SATA III.
I have purchased another Western Digital Caviar Green WD20EZRX 2TB 3.5" SATA III and would like to add it to my PC as a second HDD.
The only power cables I have available are a 4 cable Molex (red, yellow, 2 x black) and an 8 cable Molex (2 x red, 2 x yellow, 4 x black).
The HDD which is already installed is connected via nine cables (includes 3.3v) SATA power connection. This is connected to the power supply box with a 5 cable connector (includes 3.3v orange cable) the remaining 4 cables are connected to a 4 cable Molex.
I am unsure how to connect the new HDD to the power supply.
