Yes. And you will probably need to do so.
Use a couple of online calculators to tally up the wattage requirements of your system. Add 40% for some extra margin.
And double check the physical dimensions of the unit itself. Be sure that will does indeed fit in the place of your existing 450 Watt PSU.

Here is a handy chart for sizing a power supply.

RTX2070 numbers are not there yet but 650w should be fine.
I have no problem overprovisioning a PSU a bit. Say 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
And... buy only a good quality psu.
Here is one chart of psu quality:
