How much power do I need for my PC?

The best power supply for your PC build is the one that provides the right amount of wattage to all components simultaneously. Manually calculating this requires that you multiply the total amps of all components by the total volts of all components. The result is the total watts that your PC build requires.

Is overkill PSU bad?

As long as it’s from a reputable company and it has enough to power your system, it should be fine. On the plus side, having an overkill PSU will make it more efficient and cooler (at 70% ish of your usage I think). … Your system will only draw the amount of power it needs so having the extra headroom isn’t a bad thing.
