Mac Pro 1,1 (2006) power connector options
Paul Womar
I've used up all the hard drive bays it's cobbled together witht he side
pannel off taking power from a splitter in the DVD bay (both of them
filled too). So I'd like the get the side of the box back on so need to
find some extra power from somewhere, does anyone have a service manual
or anything that shows what other options may be suitable, I see there
are some 6 pin connectors near the extra SATA connectors and I'm
wondering if they may be suitable...
Thanks, Paul.

You may be in luck. I think they were for extra power for graphics
boards that needed it, like the unlamented XT1900 I once had in mine.
If it were me, I'd call one of the disks an offsite backup. Maybe swap
in something bigger in one of the other three bays.

Those are for graphics cards with higher power requirements - not sure
what V and A they supply. The 4870, for example, uses both supplies.
I've got a 2008 Pro with SATA Blu-ray drive in the lower bay and had to
run a SATA cable from the motherboard up to the bay so I'd guess you
could run the power via the same route i.e. down from the bay by feeding
the cable through the hole at the rear right of the bay once you've
taken out the optical caddy.

Yeah that's the question (voltages) as well as "what's the connector
called"?

Interesting, I coudn't see any room to do that whilst all 3.5" bays are
filled tho, are all your bays full?

It's certainly an option, but then, so is just leaving it with the side
off! At the mo it sits relatively flush against the vertical wooden
side of the desk so I think airflow is not too bad and I can't see the
open guts of the machine.

Went for the Crucial 128GB M4, pretty impressed with it, machine start
up time is quicker than my Windows laptop resumes from hibernation, big
Java apps now launch in reasonable times. None of which is probably
really enough to actually justify the expense of course but that's not
really the point!

I bought a PC Radeon 4870 on eBay to flash for the Mac Pro. It came with
two power cables going from the Mac motherboard style plug (two of which
are also on the graphics card) to the normal molex PSU plug. I had to
buy two cables with the motherboard-style plugs on each end to connect
the Radeon to the Mac Pro since there are no spare power cables hanging
around in the Pro as you know.
This is the type of cable:

0-5870-NEW-/150529344316?pt=LH_DefaultDomain_0&hash=item230c3f833c#ht_25
66wt_1141>
The molex-pcie cable looks like the one below except it's only got one
molex connector:

The yellow wires suggests 12V and some graphics cards use a fair bit of
power so it looks hopeful for running your SSD from the motherboard.

I've got both bays full - DVD writer in the top one using the stock PATA
cable and a SATA Blu-ray in the lower bay using the stock power but with
a SATA cable running through the hole mentioned above down to the
motherboard SATA connector.
The other motherboard SATA socket is cabled to an eSATA socket on a PCI
slot cover.
The SATA cable's plug is quite small but I can't remember how tricky it
was to feed up to the optical bay - not very I suspect. I don't know
whether the 2006's optical bay is any different to the 2008's.

Thanks very much, I was hopeful that the exact cable I wanted might
exist but I have instead ordered a PCIe 6pin to molex and a molex (M &
F) to SATA power cable which I'm hopeful will do the job.
Cheers.

Can you do that for a nVDIA card - I bought a G73 Board - p345h5 - but it
turns out it's a PC card, and Apple made their own G7300 - can the generic PC
version of the card be updated to the MAcintosh version?
As to the SATA my MacPro is the sort that needs too much taking out for an
eSATA though cable so I've fitted an PCI eSATA card. Anyone want the eSATA
pass through cable assembly?

Unfortunately I don't think you can with NVIDIA cards - on most the ROM
chip is too small. I'm no expert though.

It wasn't too bad on the 2008 - just undo two screws and take out the
fan assembly.

Have you got this up and running?
I'm tempted to add a small SSD for the system and applications without
losing any large hard disks in the Pro's case. Have you got the SSD
connected by a 'spare' SATA on the motherboard and where is the SSD
housed?

I've given up on getting hte case back on I think. The rist PCIe cable
I got was essentially the same connector as on the motherboard so I got
a PCIe extenstion cable in the hope of cutting the cable in half and
connecting it to the SATA end of a SATA to Molex cable. However now
that I've got the correct physical connections, I've checked the SSD
specs and PCIe specs and it seems that PCIe only provides 12V and the
SSD expects 5V so it's a no go.

At the moment it is just sitting on the lower front mounted fan
enclosure, attached to the motherboard by a short firm SATA sable that
keeps it well away from anything when being moved, the SSD is
essentially plastic so I think electrically its reasonably safe,
especially as the machine is wedged under a desk on two sides and even
if I hit it, I'll be hitting it into the corner. If' I'd managed to
sort the power for it out, I would think you could strap it to the fan
enclosure to keep it a bit safer.

But no, apparently not..those two 6 pin plus near the on board SATA connectors are ONLY 12volt out.
three 12volt lines and three returns.
I did scan the thread but did not see an answer , so I though tI'd post what I know here for reference..as much as my own reference as any one else for future.
This is something I did know 10 years ago..but forgot, and google bought me here.
So nest t time i need to know....the answer should be here!
