If you look at the service manual you will note that it has an X16 video slot.
HOWEVER ; Non dell cards will require F2 CMOS Secure Boot OFF and CSM ON and Legacy Option Roms ON. When installing an after-market graphics card into a Windows PC with UEFI secure boot enabled, the system may not boot. The Link Below is NVIDIA but ATI has the same Issues as do other NON DELL vendors. The main issue right now is that most cards are wicked expensive. There is a specific GTX 1030 thats reasonable and works fine.Gigabyte GV-N1030D4-2GL GeForce GT 1030
This user did upgrade the machine with an Gigabyte RX460 so there are a few choices. Also BEWARE there are Tons of FAKE cards out there now.
I have added Asus 4gb GTX 1050Ti Graphics card
SanDisk 480gb SSD drive
Also added me spare 300gb 3.5" hard drive
Pc is now super fast with great graphics
all working with the original PSU 240w
What should I be looking for in terms of physical dimensions for a graphics card, e.g. low profile, maximum length?
I've made the mistake before of buying cards that didn't quite fit, which was pretty frustrating. And I've never owned a PC with such a small form factor before.
1050TI is as good as GTX 680 from 2012 and uses less than half the power. The other issue is that these cards are OVER $200 now.
The GIGABYTE GDDR5 version of the GT1030 is fine and uses 30w.
The DDR4 version of the GT1030 is JUNK and should not be purchased.
HOWEVER 75W is asking a lot from a 240w power supply.
I would like to install a gtx 1060 which model can I use I have a i7 7700 and 16gb ram which power supply do I need to upgrade to
