550W would be plenty... even a great quality 450W PSU will suffice.
Your rig will consume less than 200W in full load.

Also the semi-modular version of this PSU is a great deal... also the 650W version is priced the same as the 550W right now.

The FOCUS series PSUs from seasonic are rock solid too... even though it's a 450W unit, it will still have plenty of room in your case.

Thanks for the answer. Also, in your opinion, would a 550W PSU still be enough if I decided to upgrade my GPU to a GTX 1080Ti? Or would I need to upgrade my PSU?

Well, a great quality 550W unit will be enough since the power consumption with a 1080ti will be around 350W in full load... Going with the CX650M will be a great choice since your're thinking to upgrade your GPU... it will give you more headroom.
