Hello, could anybody help me to choose the right psu for system listed below, please?
Gpu: asus strix rtx 2070
Cpu: i5 9600k
Motherboard: literally any decent for a slight overclock, like 0.3-0.5 ghz.
Ram: 8x2 ddr4 2666 probably hyperx.
And the psu I currently have, it will be delivered tomorrow, so I can refund it: bequiet pure power 600w 80+ gold.
So, will it be enough, or should I refund it?
 
Power supply 600W Be Quiet Pure Power 11-CM
This one psu exactly. As they say, more details the better. So, it shall run it smooth like 8-12 hr per day? And with an oc I mebtioned? Sorry for being messy, I'm just worrying damn hard, my first pc which I build part by part.
