Thanks for reading. My PSU states max 385W. I have an issue with my HD Radeon 7870 gpu not showing up in the Device Manager after installing the software. In BIOS if I change primary display from auto to pci-e, it'll revert back to auto upon reset. I posted on another site where it was suggested my psu isn't enough for such a strong card. I checked a psu calculator and it says my build needs 600W. The onboard fan spins on the card so I know it's receiving some power. So is it just not enough then? Think I'm in need of a stronger psu?

I wouldn't power a sandwich maker with a 385w generic psu, you have to use a proper psu if you don't want your home to burn down.

The software for that card is it right. Yes the PSU is to small for that card. But it should still install the software.
