X51 R2, Quadro GPU's?

Has anyone successfully installed a Quadro p400 in their alienware x51 r2? From the GPU's requirements, I don't see any showstoppers but I could be missing something. The p400 is really low power (30W or something) and small so I shouldn't run into the standard issues that most folks have trying to upgrade to a more recent gaming-centric GPU.

The card is powered from the PCI slot so wondering if the x51 r2 PCI slot and riser will supply power to the card or if there is anything that needs to be done to supply power to the card?

My x51 R2 currently has the following specs:

- i7-4770

- 16GB Ram

- 330W power brick

- Radeon R9 270x (works just fine so PCI slot and riser are working for data)

- Windows 10 Pro

- BIOS A12

I bought this computer back in 2013/2014 to be an HTPC (serving video files and playing blu-ray discs). I don't play any games and at this point I basically use it for MS Office stuff, some basic lightroom and photoshop, and as a plex server. Since I don't care about gaming it seems like a low-end quadro would fit the bill for now until I bite the bullet and upgrade but wanted to see if anyone has any experience or any reasons why it shouldn't work.

Thank you!
