Have only 2 PSUs works on both, from 1,25 to 1,45 it is no problem, will test more once i have that heatsink on
BTW, might have killed the 2nd one, had it working perfectly, but then i tried to reinstall the original Fujitsu cap, which worked after the 3rd try, but now it doesn't recognize power button, i think the heatcycles might have killed the NB... Initial problem with the 2nd one was shorted capacitor on Vnb if it interrests you
EDIT, Board one tested to 1,65V seems back in bussiness, but nb filtering looks like this now
EDIT2: The board i mentioned i killed lives again, but VRM is allso dead again
