hi.
there is strange problem with this MB: Power sequence proceed but when reach to PM_PWROK turn off.
I cut PM_PWROK from KBC to PCH so MB stays ON and all voltages on all coils is OK. BIOS is TRUE, PCH(HM57) changed with new one. I cut another signal after PM_PWROK and be sure that PM_PWROK is main cause of this issue.any idea?

Hi, P.zonouz, where are you?
I look at your posts, but I'm never understand what you want..
South bridge generation Ok?

I can not understand you, Sought bridge (PCH) generates voltages as described in power sequence page end of schematic. Just after PM_PWROK rised and transfered from KBC to PCH MB shuts down for 3-4 seconds then powers ON then power off again and again. Is there dark part in my description?

Rejected and give it to client.
