run only windows?
The power should be enough?

Lol buy a mac to run windows.

 

[Ace134blue]

Yes it would work good, and yes there is enough power.
Thats the fastest GPU in the world right there

(Offopic) and....
i have a macbook pro so dont worry ..

Is posivel ?

Very Possible

It is possible to run a gtx580 in snow leopard, and it works very well.

580 needs one 6-pin and one 8-pin PCI power.
570 needs 2x6, which might be less hassle setting up.

Still debating which to try now my 480 has gone to someone else.

I tried a gigabyte GTX580 in my 2008 Mac pro (running Windows7).
The six pin power I pulled from the mainboard and the 8 pin I pulled from the molex plugs from the dvd drives.
At first it seemed to work fine but after a few minutes the fan on the videocard stalled and the card went too hot and the system shut down.

This same card does run ok on a i7 PC

 

[jadolfo]

What card you use in boot 8800 gt?
Maybe is because the psu not enought power ..

Don't ever to that!
The 8 pin connector is supposed to deliver up to 150W, the molex line is intended for a DVD drive that doesn't consume even 20W.

It is highly likely to burn the PSU with attempts like that.

The 5870 in my MP uses 2 6-pin cables.

The videocard comes with 2x Molex to 1 8 pin cables (2x)

A friend has a GTX 480 working with this setup

Nothing to argue here. But the Mac Pro has a custom PSU. Standard PC power supplies won't have a problem with powering a graphics card from a Molex line. However, it is very likely that Apple adopted the Pro's Molex line to just be able to power a bunch of hard drives or optical drives.

Ah ok, that makes sense. thanks

 

[jadolfo]

so do you recomend one drive bay psu ?

 

[jav6454]

I wouldn't even recommend the GTX580 in a Mac Pro.... unless, you want nice fireworks due to insufficient power through the old as **** Molex connectors.

Newegg has a $30 5.25" PSU which is used by some users here. Haven't heard any complains so far.

Would using two 6-pins possibly work? I tried and got black screen in Windows.
