Using external PSU for additional Harddrives
Hi there,
I have got a Mac Pro 2006 2ghz (Basic model). It is not my every day Machine, it is more likely my toy. I found out today that it has in addition to the four HDD enclousures two sata ports on the motherboard. I connected to them two sata cables. Since I do not have any powerconnectors left over, my idea was to use a second PSU to power the drives which I want to connect to these extra SATA ports. So my question, will it harm my computer/Mac if I will power a Harddrive from another PSU than the Mothermoard is powered and connect the sata data cable to the motherboard?
So it would like this:
1. PSU of Mac pro Powers mother board
2. External PSU power's two HDD's
3. Connect the two HDD's to the motherboard (Sata-Data Cable only)

Can you clarify your current setup.
The four HD bays which you access from within the system have both data & power.
The upper bays are for optical drives and you should have two connections already there to hookup two full sized optical drives.

There are near the two six pin connector for the GPU two SATA ports, google "hidden SATA ports mac pro 1.1". So I have two optical drives, 4 HDD in the HDD carriers, and these two SATA ports. I d'like to use these two ports additionally to the rest (there is not any power connector left over) . Can I power the these two HDD's with another Power Supply and then connect the Data-SATA cable to the ports on the motherboard?
