update:
tried with Corsair CX500 psu, still the same problem.
my switching adaptor is missing, i forgot where i put it

my mini miner is brand new from baikal.
i didnt tweak, edit or anything else.
just plug and play from the beginning.

then it just stop mining, both indicator led on ethernet port lit from the moment i power it on.
it cant get ip from router. router is working fine, internet connection fine.
i can browsing etc with my pc.
other miners work fine too.

i will try  a suggestion from age1314.
