Acer Aspire TC-780 I6710 NL‎ want to buy a graffic card that fits on motherboard

Hello,

i want to put an graffic card in this pc...

The power supply is replace by me for one of 550 watt....

Now the problem:

I thought I get a nice card and went fot this one https://www.videokaartshop.nl/product/747896/category-207252/asus-geforce-strix-gtx1050ti-o4g-gaming.html

ok i thought its a bit long, but i can take the hard disc and plaze that a bit more to the left, so the card can slide easely to his place...

Wrong.......

The lenght was not a problem but the thing is with 4 cm to thick

If you look at the picture of the motherbord you see a blue plug next to the pci-e, and thats the bottleneck... so there was no room for that card because of that stuppid plut that is to narrow on that pci-e slot......

So the question is:

What cards can i put in a motherboard like that? Because all the cards that i saw will give a problem because of that plug.....

i would like to have a good card for some games... can spent around the 200 eurro

So i need some good advice in bying one that will fit on that motherboard....

Thanks
