Different drives will consume different amounts of electricity, called AMPS. If you draw too many amps for a system, it will drag the voltage down a bit.

You didn't say how many amps each 12v supply has. With 650W, it certainly should be enough.

Try unplugging one of the disks that DOES come up and then see if the disks that you say don't come up finally will work. That should rule out whether it is the drives or the power supply.

What brand is your power supply? Some brands exagerrate their power suppliy's capabilities.

Here is a short article about power supplies and amperage:

How many amps does it say are in the 12v legs? And are there two 12v legs? Or just one?
