Dual GTX1080Ti for 880-149

HP Recommended
HP OMEN 880-149
Microsoft Windows 10 (64-bit)

Hi, I purchased today HP OMEN 880-149 PC with a GTX1070 card. I need to upgrade it to dual GTX 1080Ti. In one of the HP OMEN videos where they were showing how to replace the GPU, I saw some kind of connector that was combining both cards together. It was connected to the upper connector of GPUs. Looks like a connector that combines the power of two cards into one on the hardware level. I don't exactly know if I am right about the purpose of that connector. So my question can I upgrade my PC to dual GTX 1080Ti and where to get that connector. And I also need a bracket for the second GPU, where can I get that as well? Here is the link https://youtu.be/LGIZOIEim-U?t=76

@isaaydin , welcome to the forum.

 

The device that connects the video cards is called a SLI (SLY) bridge.  These normally come with the video cards.  If not, you can buy one from Newegg or any other online computer component seller.  Here are the components for your computer on HP Partsurfer:  https://partsurfer.hp.com/Search.aspx?searchText=2HJ72AA

 

The Part# for the SLI bridge is listed, but HP no longer supplies it.  I am not certain where you can buy the video card bracket.  I suggest that you look at the one in your computer to get the Part #.  You can do a search for it.  Also, you will have to upgrade your power supply supply unit (PSU).  It is only 500W and most likely doesn't have the necessary 2 x 8-pin PCIe connectors necessary for both cards.    I am concerned that you will have Heat problems with two high powered cards in your mid-size case.

 

I suggest that you choose a manufacturer of video cards, such as MSI, and contact their Tech Support for help with choosing the best cards for your system.

 

Here is a HP Knowledge Base article to help you know what to consider when buying a video card:  https://h30434.www3.hp.com/t5/Gaming-Knowledge-Base/Upgrade-Video-Card/ta-p/7447100

Thank you so much for taking the time and providing such a detailed response. I really appreciate it.

 

You are right, I also think that two titans might cause heating issues. So I probably should install one 1080Ti since I am working with high-resolution videos and Adobe after effects and Davinci Resolve. The power of the GPU is mostly needed for rendering. Do you think that adding one more GTX1070 will be as powerful or at least close to having a single 1080Ti?

You are very welcome, @isaaydin!

 

I will have to be honest.  I am not certain if the two 1070's would do the job or not.  I believe, however, that the two cards have to match to work in SLI.  HP has their components made to all work together and are made to their specifications.  Therefore, they are not always the same as the retail models.  This means that the 1070 in your computer may not match a retail version.  Here is the same card on Amazon:  https://www.amazon.com/HP-NVIDIA-GeForce-GTX1070-909249-001/dp/B079RNCVX2

 

I have never had a reason to use SLI.  So, again, I suggest that you contact a manufacturer's Tech Support for help if you decide to buy other than the HP card in my link.  They are the experts on their products and would know if their card would work with your HP card.  Also, they can tell you if the two cards will be powerful enough to run your programs.
