Hello everyone! I've tried upgrading my ThinkCentre M91p with a R7 250X graphics card and a 500W PSU. The graphics card is slightly bigger than the one that came with the desktop, if that information is any helpful.
The problem is that the PC turns on, but my monitor doesn't recieve any output. I checked the slots and everything is plugged in as it should be. According to some similar topics, the GPU is too strong for the BIOS. Is there any way to fix this? This is the only graphics card I have.

See this recent thread: Lenovo-m91p-White-List-GPUs
M91p BIOS has two modes, UEFI and a
compatibility? Legacy mode, I suggest you try both. Also, check that the BIOS setting for the Video Devices is set to [AUTO], or has the Multi-Monitor Support = Enabled. Otherwise, it may only use the internal graphics, ignoring the card.

Thanks for the responce, BiggAl! The Video Devices setting was already AUTO, and i couldn't find the Multi-Monitor support setting and neither the BIOS mode. I'm not quite sure what to do now.
