--- Comment #4 from HV suzaku.29a@gmail.com --- Not at the moment. Maybe some cheapo PSU lying around, but i'm not sure it's gonna be able to handle the draw.
I currently have an Antec VP500P (500w) and the GPU works on Windows 7 on the same PC (installed along Debian and Gentoo). It's been used extensibly on Windows without any issues.
My friend's PC does have a more powerful PSU (some Seasonic 750w). So maybe during init it needs a bit more of a push on linux to start up. Is this possible?.
I'll borrow the 750w PSU during the weekend and give it a try.
In the meantime, is there anything else I can test or info I can provide?. If not, I'll update/confirm during the weekend.
