I am wondering if the Corsair 500W Semi Modular PSU will be enough for this system.
i5-6500
R9 380
2x4GB Kingston FuryX DDR4 RAM
WD Caviar Blue
Kingston SSD
500W is well enough.
If it's the CX500m you're looking at, then i suggest you look somewhere else. The CX series are of bad quality and have cheap capacitors that can burn out very quick in such a system.
Here's a much better unit: https://pcpartpicker.com/part/evga-power-supply-110b20750vr
