How to Get 8V?

[nuke]

I have a ps1 screen that I want to attach to my gamecube mobo. I just finished soldering the composite,right and left audio and ground. Where do I connect the 7.5V to though????

To what the psone screen or the gamecube?

To the PSONE screen.
Edit:I want 7.5v coming into the screen so to the gamecube

Bump(I still need help)

If you look at psone screen pinouts you'll see where to wire the 7.4 volts. For the gamecube, unless you have a custom regulator you can't run a gamecube on 7.4volts.

Never mind I fixed it. Thanks though!
