Hi
I have a big problem.
I have 5 miners and all of them work fine IF a let them work one by one...even two together work fine.
BUT.....
If i want to let 3 miners work together, the PSU crashes.
The miners, the hub and the MR-3020 are ALL conected to the same PSU-Molex cable-tree.
The PSU has 550W....
What can be the problem?
Can it be that the PSU is too old even it has NEW 550W?
Pls help me ..... i cann't solve this problem
what is the rating AMPS of PSU 12V rail is it a single one?I have a big problem.

PSU-Model: pentium iv & pfc model lc6550G version 2.0
MAC DC OUTPUT:
Voltage 230V:
+3.3V -> 35A
+5V -> 40A
+12V1 -> 16A
Current 4A
+12V2 -> 18A
-12V -> 0.8A
-5V -> 0.5A
Frequency 50Hz
+5VSB -> 2.0A
BLK - > COM
GRN - > PS-ON
GRY -> PG
I made a shortcut betwen the green and black cable to turn the PSU on without motherboard.
1. Chosse a single rail PSU
2. When board is OC-e it is eating about 9.5 Amps
So if i were on your shoes i will connect just two boards to this PSU when i am absolutely sure that each board is connected on a separate 12V rail. Does this explanation clears up a mastery crash;)
And do not push it to much magic smoke will come out sooner or later. I am not joking here i am serious
So you say that the PSU is too poor to run more then 2 boards at once?
Will a new PSU work better and how much power do i need to run all 5 together?
Would this one do the job?

First please excuse me i just saw that it is Avalon2 boards. So i do not know what the board consumption is but i know that it is getting close to Avalon1 And definitely i say that i would not run more than two broads on this PSU. Whatever you do choose a SINGLE rail PSU. Do you know to what rails are the boards connected i guess no.. and so on

Yes it will do and you will have a room for more boards this one is too powerful.
My advise is to measure exact board consumption on 12V and choose appropriate one you can save a bug for sure. If this is not an option for you go with 1000W
