DVI Technical Question

[CrazyDemon]

Hey everyone,
I am working on a little project, and I am wondering if anyone knows how much current can be safely drawn from the +5V line in the DVI connector.

Pin #14 is what I am referring to.

I would assume this varies from one video card to another, but there should be a minimal allowed current in the DVI standard. My project would require maybe 50-60mA.

Thanks in advance to anyone who might know.
