Well, yes and no.
You have a PCIe x16 slot, which means the card is compatible. But no, you won't be able to run it because your power supply is only 220W. That's tiny. You probably won't be able to run any decent video card on that.
Basically, your best option is going to be finding a regular-sized case and moving everything into that. Then you can get whatever video card AND power supply you want.
Although the rest of your system is passable, not great. So if you were thinking about putting together a new system at some point ... well, replacing the case, PSU and video card would basically be half the parts for a new system anyway. So starting from scratch is worth considering.
