Upgrading my Power Supply

[Truckerjeff]

Do I have to upgrade my psu if I want to upgrade to a RTX 3080 and if I want to do any overclocking with my CPU? 

 

This is my current build:

 

CPU: AMD Ryzen 7 3700X (not overclocked)
PSU: bequiet Straight Power 11 750W Gold
Storage: 2x SSD(870 QVO 1TB, 860 EVO 1TB), 1x HDD 2TB(7200 RPM)
GPU: 1050 Ti
Mainboard: Rog Strix B450-F Gaming
Monitor: 2x MSI Optix G24C4

Fans: 3x

You will be fine but it sounds like you will be daisy chaining it.

Rule of thumb is; Maximum CPU and GPU power draw + 50% = Power supply wattage. 750 should be fine.

As long as you aren't trying to go bleeding edge world record performance, you should be fine. The 3700X is a pretty efficient chip.
