My Enermax Liberty ELT620AWT has died...
It will not turn on, when power is applied the fan spins for about 0.5sec and then nothin! There are no apparent crispy bits nor did any magic smoke escape.
When it first occured I noted that the PS_ON line (Pin 14, green wire) was at 1.29VDC and did not change when the power ON sw was depressed.
I tried manually pulling pin 14 to GND and this allowed the Enermax to fire up but this no longer works...??
Installing my spare CoolerMaster PSU, pin 14 starts at 5.19VDC and goes to less than 0.1VDC and stays there and PSU fires up.
I assume my MoBo has some sort of latch that pulls pin 14 low and holds it there but with no cct diagram I have not yet confirmed this.
Given the spare PSU works I also assume that my MoBo is not the cause of the problem....
If my assumptions are correct, it would appear that the PS223 monitoring IC is fauty.
I.C. specs are HERE
I have tried to locate a new PS223 chip withouit sucess.
Any advice, ideas etc appreciated.
