I have a confusing GPU problem.. (Experts please)

Okay, so about a month ago my mom bought me a lenovo computer (Lenovo k450e) which has an Intel i5-4460, and a Nvidia GeForce gt 720. I was looking into upgrading the GPU to an EVGA Geforce GTX 750 Ti, but I really can't figure out if the gtx 750 Ti will be compatible with my motherboard, which has been a real pain trying to figure out the name of. My motherboard is the "Lenovo 10181" which is extremely shady.. Any advice? (My problem is the PCI-E Ports being too much or too little..)

  1. According to newegg, the Lenovo K450E comes with a gtx 750 Ti already....so are you sure this is the model you have?

    I have the gt 720, the more expensive model has the 750 ti. (I own the one for 700$)
  3. my bad, i forgot lenovo has the same base name for multiple products.

    from the looks of it, it can support the gpu. i know the chassis can hold the card because it has four pci lane slots. all you need to do is look and see if your gt 720 is plugged in through a full sized pci-e lane. it should look like the one at the top:

    if it is plugged into a full sized one, aka a x16 lane slot, then it will be fine and your upgrade will work well. if it is a half size like the one in the middle, i honestly don't know if it will work but it could.

    Yeah, I'm almost positive the GPU is plugged into the 16 slot. There are 3 small slots so the one big slot is 16x?

    If so, then i can go with this upgrade?

    "almost positive" isn't a very good position for someone about to spend $150 on this. The gt 720 will fit in a smaller pcie slot than the gtx 750 ti, so its important to make sure.

    Just look at your motherboard. Look at the slot the gt 720 is plugged in to. If that slot is longer than your finger, then it is a x16 slot. Or better yet, if it says on the pcb "PCIE x16" anywhere then you are golden!
    However, if the slot is slightly smaller than your pinky, then you probably have a x8 slot and I do not know if the 750 ti will fit/work in that. I think it does, so long as the slot allows for bigger cards to be put into it.

    Okay, It is a 16x slot. So I can buy the card and it will work?

    Knowing that, you can buy any graphics card and they will work, so long as you have the power suppy to handle it. The 750 Ti requires a 300W power supply, but so does the gt 720 which you have, so you should be good to buy it.
    One of my buddies has the 750 Ti, its a great card, hope you enjoy it!
