I have not ever done a GPU add to this particular model of PC. I have done other prebuilts and it's not uncommon to run into issue of various types when trying to do so. I have already mentioned the adapter needed. Your BIOS may or may not be locked to either a specific set of graphics cards, or none at all. You certainly will need to measure the space you have available for both the GPU and PSU.

What I would suggest in a case like this would be to do a targeted search on your specific model, possibly within the Lenovo forums or such if they exist, and see if you can find examples of others fitting a GPU and what possible challenges they had doing so.
If you can't find and/or are willing to take a chance you might find a suitable PSU...

Many of the large name branded pre-built PC on the market are designed not to be "upgradable". Often the PSU is built into the case, or some strange off standard size, connectors, things of that nature. Most often these productivity computers are buy as what is offered, or nothing.

I second the above in that, to be sure we need a model number to take a look.

Generally speaking there should be an ATX power supply in there. It could be SFX, but that is less likely. If you look up those PSU units as a standard you will note both the screw attachment locations as well as the plug standards common to them. After that it should be relatively easy to look at your unit and make the determination on that.

Aside from that, if you are planning to add a GPU to this unit make sure than you have the proper amount of open slots around your PCI-e slot on the mobo. Most modern cards of any usable gaming power are going to take two slots. The space will be needed "below" the PCI-e slot in most configurations.

Of note it only has a 10 pin and 4 pin cable. You will need an adapter for this to work with your motherboard on a standard PSU.

If you can't find and/or are willing to take a chance you might find a suitable PSU, add it and make sure it's working right, then (if so) buy and add the card to see if it will work right.

Yes. You will need this.

While your PSU is of the ATX form factor, it does not follow ATX specs. Note there is no +3.3V or +5V.

There's also no standby power, which is interesting. Without that, I have no idea how this PC would be able to sleep or suspend.

Are you sure you want to get into this? Seems like it'll end up being quite the basket case.
