Emax

Hi all,

I'm in the process of upgrading an Emax SE Rack to SCSI and installing a card reader. 

On my first Emax, the HDD power comes from the main PSU loom, it seems the third set of power connectors are not connected to the mainboard, but are lengthened and terminate in a normal female HDD power connector. This is then connected to the card reader.

On my second Emax, the one I am updating, the power loom has all connections connected to the mainboard. So I am wondering where the best place is to take power from?

I have a spare PC power cable I can use to take power from anywhere on the machine. My gut says to just solder it onto the same mainboard power connector at the same place the first Emax's loom takes the power.

Is this the best way of doing it? Is there a better way of doing it?

Thanks!

Nik

I have taken a splitter at the floppy and also at the main connection.
Seems to work fine in either case.

Media drives do not use the +12V, they only actually use +5...

Thx,
Ted

Thanks Ted, splitting at the floppy connection worked fine, only used 
the +5 and ground as well.
