One of these:

Its worked fine up until today.

you may have killed it.

try 1 stick at freq 100 directly to the pi

see if it runs.

4 sticks on that hub is a lot of juice.

can you read the brick specs.

1 stick will pull 10 watts at freq 200

so if the brick reads 5v volts and 14 amps

it should be okay,

but if the brick reads 5 amps and 12 volts

some math 5 x 12 = 60 convert to 5v means 60 x .85 = 51 watts that is 12 to 5 volt

so 4 sticks at freq 200 = 10 watts x 4 = 40 watts

so you have a 51 watts brick maybe ? well seems good 24/7/365 means derate by 80% so 51 x 80% = 40.8 watts

so four sticks at freq 200 is pushing the brick hard as 40.8 is close to 40

and freq 250 would be over use of power.

I believe you killed off the brick..
