My Power supply has 550 Watt (Corsair VS550) and i was wondering if thats enough or i should get a new one? (Reason im asking is because my CPU and Motherboard is on its way and has not been put into my build yet)

CPU: i5-8600k
GPU: Gigabyte Radeon RX 580 8GB AORUS
RAM: 16GB (8x2 2133MHz)
Motherboard: ASUS ROG STRIX B360-F Gaming
