Using external PSU for additional Harddrives

Tekst:

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)
