Even the 2080(I see you have the 2060 which has a 500W PSU req.) only needs a 600W. Save some money and buy the 650W model instead. It's still gold rated so I'm not asking you to sacrifice quality.
Okay thanks for that information matethe power supply is serous overkill. if running everything at stock, this uses less than 300W
if you arent going to overclock, the SilverStone Essential ET450-B Bronze 450W Power Supply is plenty, and only AU$49
If you are going to overclock, then the Silverstone 650W at AU$75 is more than adequate. -- 550 would be plenty,. but the 650 is cheaper.
I would consider a 2TB HDD. games now can exceed 100GB each.
Do you really need the DVD Burner nowadays?
If Wireless N is all you have, that one is fine,but I'd suggest ethernet for a desktop that isn't moving anywhere. If you have it, Wireless ac is faster than N
