Motherboard: Gigabyte 2AC8 (its old)
Old GPU: XFX Radeon 6770
New GPU: Gigabyte Radeon RX 550

Here's where things get funky for me. The old card works fine. I've uninstalled drivers (even though that shouldn't matter). I've tested the new GPU in my computer and it booted fine. In the computer its going in, though, I don't get any signal. I'm not sure how I need to approach this.

Sometimes....in the BIOS you have to designate that there is an external graphics card.
I would go in the BIOS and look around for this.

or perhaps the PC it doesn't work in....doesn't have the proper power supply.

There's a 400 PSU in the desktop that was running an XFX Radeon 6770. Just doing an upgrade to GPU that doesn't even need a pin connection. The PSU isn't the issue.
