[SOLVED] Will PSU and CASING be okay

[Shadmans]

My PC components are :
Monitor -LG 22MK600M
Processor- Ryzen 5 3600
MoBo- MSI B450M Tomahawk Max DDR4 AMD AM4 Socket Mainboard
GPU- Sapphire Nitro Plus RX 5700 XT 8G GDDR6 Gaming Graphics Card
Ram- G.Skill ripjaws V 8 gb 3200 MHz (2 stick)
HDD- Seagate Barracuda 2TB SATA 3.5 inch HDD
SSD-Transcend 256GB 220S NVME PCIE M.2 SSD
PSU - Antec HCG-650W Gold
Casing-Antec DF500 RGB Dark Fleet Series Gaming Mid-Tower Casing
I want to know does the casing have good airflows and is the psu right for the components?

Airflow, no it doesn't. The parts you've got so far are fine but you should be looking at a 750W unit.

Should I change the casing then??
