Need Helpe With My +12v Rail Real Bad!


Recommended Posts

could it be the motherboard do you have another power supply to try it on have you ever drop or chipped somthing off of this motherboard i have never really heard of the wire getting hot do you have good case cooling ( might not matter but worth asking).

i had this happen on an old gigabyte, i was trying to get a hsf on and the screwdriver slipped and busted off a itty bitty chip (resistor i think). it made my old 1900+ run at 1.1ghz and also cause the 20 pin plastic atx plug to turn brown around some of the the pins after a few months of use like that. so you might want to check your board like capthowdy said as this technically could be a problem also.

hmmmm well I got the voltage on 1.46V at load and it seems to get very hot. The time when it melted the 4-Pin power connector was when it was running at 1.51V at full load. Would you guys like to see a picture of the melted 4-PIN connector if I still have it?

Sounds like you might have a bad connection IE: You pulled the cable out of the crimped end leaving it with little to no wire... That causes heat/sparks which causes melt...

 

I highly doubt this is a PSU problem (originally), and to draw that much current through the P4 connector is next to impossible on it's own on a celeron... for that to happen you'd have to draw WAY WAY WAY WAY WAY WAY more than 17amps across that connector/ 2x12v leads for it to melt on it's own...

 

IMO, you pulled the thing out by the wire...
