Firstly, not worry about bottlenecking. As long as your CPU can perform to your FPS goals (if gaming), and GPU can perform to your visual goals, you’re fine.
With the PSU, we have no idea. “Peak power” is meaningless. Look for the “continuos” output, which will be a lot lower than the peak.
Could you please share the power supply’s model name, or post a photo?
Which exact 1050ti (some require a PCIe cable)?
We also need to know the exact PSU to ensure it has enough connectors, and if it’s quality is fine.
