Hello I’m buying a new power supply but it’s from the uk and I’m from eu and I don’t really trust adapters I was wondering if I can use my old power supply power cable to power my new power supply

ok? so i should sell a broken monitor on ebay say its the new generation 4k brand new limited edition and charge about 20€?

I would say it depends of what you have.
Not having anything decent, you will probably need to replace everything, so maybe starting with integrated graphics by buying like a 300$ "base pc" and later down the road buy a GPU
If you have somthing like an fairly recent i3 and 4+ GB of RAM, i'd say GPU first (something like a RX460/ GTX 950/1050)
