Do I have to remove the Motherboard to install a Power Supply?

There are two yellow wires and a black wire which go down from the Power
Supply to a side of the Motherboard and disappear under it between the base
of the box and the Motherboard which it is screwed onto. So I got to lift
the Motherbaord out of its fastening and find where these wires go? And
then I got to get a soldering iron? Thanks.
 
Most unlikely. Soldering a motherboard outside of the manufacturers plant is
only done by skilled people to do specific repairs or minor revisions.
Anyone else is likely to trash the motherboard.

It would be a good idea to tell us what the Make and Model of the mother
board is along with the CPU type & frequency / model name. This will tell
use what the power and connector requirements are.

Off the cuff, I would say that the wires disappearing behind the motherboard
are looped under there to keep them out of the way - that the connector on
the end may not be plugged into anything, just hidden from sight.

2 cents.

It would really help if you could figure out exactly which ASUS mb you are
working with. My recollection was it was a P97-DS or something or other
but if you could find out for sure, then you could download the manual from
the ASUS website and see if there are any power connections on the
underside of the board. It shouldn't be too difficult for you to figure
out which manual you need since ASUS didn't make all that many dual slot-1
mb's with SCSI controllers. (Personally, I have never seen one that had
connectors on the bottom (but I don't get out much) so I agree with Tim's
suggestion that the wire is tucked back there and not connected to
anything.)
 
If its a P2B-DS (dual slot 1 with SCSI) then there are no PSU connectors on
the rear or an earlier dual Pentium Pro class mobo (I forget the model for
the moment, its in the garage :) that has a CPU daughter card called
something like P65-UP5 or 8 then they don't either.

Go to the asus site www.asus.com.tw and download the manual if you don't
have it at hand. If you can't find the manual, post back & I may have either
a manual or one of those motherboards - the ones I have do not have PSU
connectors on the rear...

So, if the cable is stuck there it will be necessary to pull out the mobo.
Have a good look at the case first, some let you slide out the motherboard
(when all PCI cards are removed sometimes) or flop it out the rear of the
case and that may be enough to untangle it.

Best approach for this is to get the anitstatic mat & wrist strap out, take
off all synthetics (!) , document where everything is plugged in (which PCI
slot etc.), then rip it apart - gently :)

The Motherboard slides out. The computer guy said it is like Auxillary
Power plugs for later than PII boards. Mine doesn't have them so it was
just wrapped that way. Don't know why but it was.

It turns out the case is only ASUS. Full-Tower ATX. The board is a Super
Micro PII with onboard UW SCSI. I am trying to find exactly what it is but
that's not so easy. The machine is packed back up again but I am trying to
find it with what I know. Thanks really now I know what P2B-DS stands for
It's just a dual PII with SCSI...2P2B-DS

Check the P6D series of boards from supermicro to see if you can find the
match for yours. Possible options are: P6DBS, P6DGU, and P6DGS. There
might also be other dual slot-1s they made that had onboard scsi, but the
P6D series were the most common. Nice boards too, I much prefer them over
the Asus boards.
 
Bill I have the exact board from Aida:

Supermicro P6DLE/DLF/DLS/SLA/SLS
Dual Intel Pentium II, 375 MHz (5x75)
Intel 82440LX/EX Chipset
AMI 7/95 BIOS

Wow. An LX board. That is even older than the ones I use. Why *are* you
mucking around with it? Is it just a hobby thing?
 
Because it mucks my files around the Network just fine and didn't muck my
wallet. that's why.
