graphics PC is less responsive after adding a dedicated GPU

[Muhammad Yassin]

Hello! I have an issue and I can't figure it out. I have a Dell OptiPlex PC with i7 10700 Intel UHD 630 graphics. 32GB Ram, Samsung NVMe 980 250GB. The PC was responsive (Windows UI animations was responsive) everything felt snappy. Yesterday I added a dedicated GPU Zotac 1650 4G GDDR6. I know this is not a very good graphics card, but it is my only option because I have a 260w PSU and I needed a GPU that doesn't need 6 pin power. Anyway, since I added the GPU the PC feels less snappy and responsive than before. Windows animations feels sluggish. I'm not an expert and not a gamer. I just need the PC for day-to-day regular use and very light video editing. Any idea what is wrong? And what should I do? I believe even though the dedicated GPU is not a good one, but at least it is supposed to be better than the integrated one!

 

By the way, I downloaded the graphics drivers from Nvidia's website. And I tried uninstalling and reinstalling it again, but nothing has changed.

I attached a screenshot from GPU-Z

 

I appreciate any help figuring this out. Thank you!

The Zotac website says the card draws 75w from the board and recommends a power supply of 350 watts. If you're only running on a 260 watt power supply, it could be possible the card just isn't getting full power from the board.  Your screenshot shows Board Power Draw at 35.5 watts at the time you took the screen. Can you try stressing your graphics card and seeing if you are actually getting to a full 75 watts on the board power draw?

Thank you for your reply! How do I stress test the GPU?

I chose this GPU because many YouTube videos and articles recommended 1650 or small form factor one for PCs like mine and even older ones with weak PSUs. This is why it was necessary to get a GPU that doesn't have power connector and gets its power from the PCIe slot. And even if it is not getting the full power it needs, isn't this supposed to affect it when I'm stressing it not when it sets idle?

 

Thank you
