Adding HD connector to PS motherboard connector

  Hi All,

I use an ATX case with a 500 watt power supply as a 9 drive SCSI case,
no motherboard installed.  Since the PS only has 4 HD connectors I had
to use a Y cable on each in order to get a total of 8 HD connectors.  I
still need 1 HD connector for the 9th drive.  I use the +12 off the
motherboard connector to power 2 80mm fans (pins 7 and 10).  My idea is
to add an HD connector here for the 9th drive.

My question is, does it matter which GND pin I use for the +5?  Since I
use pins 7 and 10 for the +12 I was thinking I could use pins 4 and 5
for the +5.  Or, should I use the same GND pin for both voltages?  Is
there anything else I should know before I solder in a HD connector and
plug it into my HD?


Thanks for any help,

Charles

All the black wires for all the connectors go back to a common point
within the power supply, for an AT or ATX unit. Use which ever black
wire you fancy - it won't make any difference.

Thanks Sue.  Since I know very little about this stuff I wanted to

 Just to clarify, an anonymous response to a posting in a newsgroup is hardly
"verifying with the experts".  Not everything you read on the Internet is
correct.

I'm not saying that Sue is right or wrong; just that you should use common
sense and take appropriate precautions (like using a multi-meter to verify
the ground, etc).  I see people asking for advice in other newsgroups on
things like wiring their house, and it just makes me shudder.  Or health
advice...  You might as well stop someone on the the street, and ask them
what their opinion is.

Ah, well, enough ranting for a day...

Hi Clint,

While my knowledge is limited I did do my homework before I posted.
Also, my ability to read schematics is limited but I had a feeling my
idea would work.  I posted my question here to get some other opinions.
 I will wait for other posts before I actually do the work so I
understand your statement.


Thanks,

Charles
