Upgrading GPU (870-275na)

HP Recommended
HP Omen 870-275na
Microsoft Windows 10 (64-bit)

Hello guys,

As I've been out of touch with upgrading and building pcs, regarding part compatibility, etc.
I wanted to find out if I can upgrade my 1070 gtx to a 1080ti in my 870-275na?
As the case is quite small, would able to fit it because of the size and will my 82F1 motherboard be compatible?

Thanks in advance.

Hello @RedlineTrucker 


You have two issues.

1  is easy... Simply look up the length of the card specs from the specific MFG you are purchasing from and take a tape measure and measure the inside of the case. You will see if it will fit or not. There are various versions of a card that vary in size from full to mini.

The power supply in it now shows 300w Mini ATX in your specs. You will have to upgrade this also, depending on what the requirements are from the video cards MFG also.

Those systems came with both a Mini ATX and Full ATX power supplies. Your 300w mini which will probably be installed with an adapter plate over the Full ATX screw hole pattern. Look to make sure the Full ATX screw hole pattern exists first.


This is a Standard (or Full) ATX pattern....
