Will dual screens (large screens) have enough power in a rather old house?

I live in a rather old 2 family house. How do I know that the electrical supply from the socket is powerful enough to power 2 large monitors plus the CPU of my new computer? I have not bought my computer yet, but I don’t want to be in a situation where I buy the computer and the 2 monitors and find out that it constantly shorts the circuits in my house. Have you any advice in this regard? Thanks.
