How many watts will you need?
There are tools out there on the internet to help you calculate this, you can simply use the calculators online to avoid doing too much of the guess work yourself.

This determines how efficient your PSU is and how much power your PC will really be pulling out from the wall. This is calculated by dividing the maximum wattage via the PSU’s rated efficiency. For example; An 80 PLUS (80% Efficiency) 750w Power Supply will draw around 937 watts from the wall to provide you with the maximum wattage the power supply is rated at, so an extra 187 watts gets turned into heat inside your PC. You can get Silver, Gold, Platinum and Titanium rated PSUs to get better efficiency although they will be accompanied by a higher price tag.
