2.5 is more than enough to power the PI at overclock. If you add in peripherals, it’s still enough to power most external (usb powered) hard drives, with a port adjustment in the config.

If you are just worried about controllers and things, you have more than enough power there. My setup is 2amp, and it powers PI at overclock, two controllers, a keyboard, a usb wifi stick, and an external hard disk.
