Upgrading GPU and I need to know new power supply power

[LokiTheZorua]

I am looking to upgrade my computer's GPU from a 1050ti to a 2070 and I want to know how much my power supply needs to be. I currently have a 450wt power supply and my current computer is a CyberpowerPC Desktop Computer Gamer Xtreme S750

I appreciate whatever answers I can get, thanks
