I'd recommend the following as more than enough for your needs with ample headroom for future upgrades:
Seasonic G-550 (550W)
EVGA SuperNOVA G3 550 (550W)
EVGA SuperNOVA G2 550 (550W)
Corsair RM550x (550W)
If you are on a tight budget, you can consider:
Seasonic M12II-520 EVO (520W)
Seasonic S12II-520 (520W)
You can actually get by with a 450W PSU, but a ~520W ~550W would have higher efficiency at full loads and, as mentioned, room for other components to add or upgrade in the future.
