I see similar questions for M9X models, but not M90P tower. I have the M90P (http://www.newegg.com/Product/Product.aspx?Item=N82E16883798325).
I installed the XFX R7 360 graphics card, but it didn't work. I'm next going to try the XFX R7 250 Low Profile Ready card: (http://www.newegg.com/Product/Product.aspx?Item=N82E16814150713)
My question is, how can I know what graphics cards will work with this machine? It seems to have the necessary slots and space (it is barebones). I also have a Corsair 750W PSU in there. The BIOS is set to use PCIE first, and then PGP for priority order.
Solved! Go to Solution.

Well, I installed the R7 250 today, and it fits just fine. However, the computer will not boot up now. It turns on, the fans spin, and there is nothing further. It doesn't even get to the BIOS.
I checked the BIOS prior to installation, and confirmed that the priority order had PCI first. I have tried another XFX card in the machine, too, with the exact same result, so I don't think I have a bad card.
Any thoughts on something I'm missing?

BIOS support for AMD cards is poor: https://forums.lenovo.com/t5/ThinkCentre-A-E-M-S-Series/m90-gpu-upgrade-problem/m-p/2049715/highligh...
The Nvidia readme file has list of supported adapters. (Ensure you're at the latest BIOS.)

Thanks, but which ReadMe file are you referring to? Are you saying this will cause the computer to not even boot?
I did update the BIOS to the latest version - 5JKT65AUS, but that had no affect. I also disabled the integrated graphics adapter via Device Manager.

Readme for the Nvidia driver referred to the linked thread. Yes, if BIOS does not recognize the graphics card, it will not boot.

Win 8.1 readme says it supports the 700 series.
The point is: It wouldn't be possible for Lenovo to certify a driver for a card or series for this system, if it wasn't recognized by the BIOS.
I was in a similar situation with a M91p, and based on the supported cards listed in Lenovo's Nvidia driver readme for that system, selected a 750 Ti (be sure that it will physically fit), which works fine with the latest (WHQL certified) drivers from the Nvidia download site.
