Franken-mac-mini - Spare internal 12v power line

I've got an '07 mac mini and I've upgraded the ram to 4GB, the HDD to an SSD, and the processor to the t7600 2.33ghz. My next project is to upgrade the lousy integrated graphics. I'm looking to siphon about 2 amps of 12v power from somewhere internally to power a gt710 gpu which is connected to the mini pcie slot via an adapter. i really don't want to run another power cable into the chassis so i'm hoping that someone will know where i can tap in to a 12v line. i'd prefer not to solder, but if that's the only way i can deal with it.

i plan on removing the optical drive which should give me JUST enough space to cram the gpu in. I was hoping that without that there'd be enough spare power to run the 25 watt gpu.

Update (05/11/2017)

I figured powering it internally would be difficult considering g it only has a 125w psu, but thought this would be the place to ask.

I do actually have it all hooked up externally right now, I've gotten it to display the Windows 7 logo/splash screen via the external gpu, but then it goes to black screen. Same when I boot in safe mode. I don't understand why it lets me use the external gpu to start to boot into Windows or select safe mode, but fails to complete the boot.

Answer this question I have this problem too

Is this a good question?

As I stated you also have a BIOS (EFI) issue which you can't overcome here. The system was never designed to support this GPU.


Ah, I thought since hackintosh users were able to run this card, there might be a way to edit the efi to get this card up and running.

But you're right, the efi does seem to be the culprit.

Sorry guy ;-{

This is not possible. Between the systems power supplies limit, you don't have means to connect the PCI interface of the GPU card within the system both physically and via the systems BIOS (EFI).

Dan's right. Even if it did interface correctly, you'd have to run power externally.
