Please help me with the cable: Early MP 2009 + PC 4890

[SolidGun]

I have been struggling for a while on this and just spent a good hour at Microcenter looking for this cable needed.

I understand that I need 2, but only links I have seen are from UK sites.

I know someone must own 3,1 MacPro and have installed 4890. Where did you get your cable?

Thank you in advance.

This is what works right? I can't zoom in enough to see if it is the right size fit as I have no experience with 1900

Yes, it works.

If you don't use a second DVD-drive you can also do it like this:

Thx for the response Cindori. I was reading through your mega post on 4890 installation and realized that 3,1 has different power cables available and just SATA+power combo out.

Great help!!!!

PCI Six pin splitter

I used this for my 4890

it plugs straight into the existing 6 pin power going to your video card (if it required separate power) i have a MP 3,1 former 8800

I have the GT120 and I don't see additional power source that this card uses at all.

Wow, powering a 4890 on a single motherboard port? Did not know that was possible! No problems under heavy load?

Didn't have a problem with it, but i just rewired it.

Just went back and read the ADC on MP PCIe power and i'm am and idiot and didn't read it well enough the first time:

When populating the four PCI Express slots, you need to conform to the following total wattage rules:

Slots one and two (not including aux power), max slot power per slot: 75 W
Slots three and four (not including aux power), max slot power per slot: 40 W
All four slots (not including aux power), max total power: 200 W
Max aux power per connector: 75 W
Max aux power for both connectors: 150 W
Max total PCI Express power (slot power and aux connector power): 300 W

Thanks for questioning that Cindori, otherwise i never would have gone back and re-read it. and would have probably ran into problems sooner than later.
