Power efficiency when using a Phanteks power splitter on dual system builds

[shalomfern]

I want to build a dual system build for my home use. But I won't be running both systems all the time.

In this case, is it better to choose two low wattage power supplies or one high wattage power supply with a Phanteks power splitter?
Thanks

In this case, is it better to choose two low wattage power supplies or one high wattage power supply with a Phanteks power splitter?

What option consumes less power. Healthy bills?
Thanks
