a bronze 550W enough?

[afrasiabhimaloy]

I am not expert at power consumption of components. recently i built my setup & it does look like this: an i5 8600k, gskill rgb 8gx2 3200mhz of speed, gigabyte z370 gaming 3, an m.2 ssd(120gb) & 3.5 hdd(1TB), cryorig h7 quad lumi as a cooler, cooler master mastercase lite 5 rgb case(3rgb fan 1 non rgb fan). im doing 4.5GHz oc on the cpu. surely i planned to get next gen nvidia gpu of $350-$450 range. im confused what TDP i am left with. do i need to upgrade my psu? or that 550W capable of withstanding 120W-150W range gpu? can someone help me with practical answers, not suggesting website to check power consumption level.

550w is enough but you must get a good quality PSU. The bronze/silver/gold/platinum ratings are for efficiency and not quality, there are some crap bronze units out there.

What 550w psu?
Also I would replace the case since what you have now is a hotbox with no ventilation and even low power systems overheat in it. Or you mod it and cut some holes in the front.
