Hello
yes i have try both settings with and without turbo card .
Nothing work .
For the power to be honnest this A1200 is an experimental box .
I have take it out this BS plastic tower and it run installed on a part of my office board

.
So its not so hard to add hardware and make test

.
The amiga is powered with a 250w PSU from that was initialy installed in the infinitiv tower .
I have a blizzard ppc and bvision card .
I have try both power possibility .
Only the amiga with special cable from me for the power .
Work perfectly without the micronik card
not work with micronik card
i have try only the micronik card put the power on .
Same not work black screen .
Then i have try both power on the micronik card and on the amiga original connector .
Not work
All outside hardware from the amiga like HD diskdrive cdrom etc are connected directly to the psu .
I am 100 % sure that i have enough power due that power problems was probably one of the first problem i got when i have upgraded my a1200

And for sure all is working perfectly before i add the micronik card .
Thank for your help i will visit the group for the board later today thx for the infos

Later
