just normal onea and i just curious..where actually this +3.3,+5,+12 supply to?
12V goes to Mobo, including the additional 4 pin to the mobo, fans, hdd, cd/dvd drives and other what nots using 12V lor5v was suppose to replace 12v's role for the processor last time (3~4yrs ago) but it didnt happen, so it powers the ram and hdd and roms as well (IIANM)
3.3v is for the signaling (Again IIANM)

hi yehlai,
u said the 12V rail fluctuate abt +/- 5 % is normal..
what abt the core volatage or processor voltage??
for my case, the processor voltage is 1.1 V .
But, its always fluctuate from 0.89V to 1.2 V..
Its this normal?
And, recently my pc will always shut donw & restarted & restarted nv end..
the only way to stop it is to switch off the power supply...
My PSU spoil???
yes and no, it means ur 12v is not stable OR ur mosfets feeding the voltages to ur proc is getting hotu said the 12V rail fluctuate abt +/- 5 % is normal..
