Re: Power Supply choice
The modular and wattage helps on the PC. What the modular is, it's the fact that the Power supply is equipped with plugs in the back so when you have spare plugs for other hardware, you won't need to insert them into their slot. It's making them cleaner and easier.
The lights are an option. Technically, a PSU with lights is a nice decoration, but isn't really needed in fact.
