Load Balancing Between Circuits

I am not an electrician, but an end user.

I am planning to build a very powerful server for running LLMs. It will have many GPUs and can realistically hit a 1500 watt sustained load. The PSU in my computer can handle 240v but I do not have access to a 240v circuit.

My question is whether it is a good idea to somehow balance the load between 2 or 3 120v circuits. If so, what are some methods to safely do this?
