Okay I got my budget PC OCed from 3.06GHZ to 3.79GHZ with the voltage at 1.5V. My +12V Rail always seems to get real hot while running orthos after 2 hours or so. Can someone please tell me is there anyway for it to not overheat. The amps it has are +12V=17A.
Is it time for a new PSU or what, and will a PSU with more AMPS heat up less? Cause I do recall like a month ago I had a PSU with 18A of the +12V rail and it practically melted into the motherboards 4-PIN connector.

Huh? The 12v rail got hot? So you stuck your hand in the PSU and felt the vregs? I'm confused... Are you talking about the the PSU Casing? the wires physically?

I'm confused too about what your saying too.

When you overclocked your system to 3.79 did you touch some wires inside the case and it felt really hot?

Need more info.

But based on your current system and ps I doubt you would need to get another power supply.

A melting molex connector isnt caused by your power supplies inability to run your system. A more likely cause is a poor connection causing sparks, maybe even between different materials like gold plated molex pins.

if the wires are hot, you're most likely in trouble! It could however be your mobo if the connector melted onto it. 17A on the 12V rail is more than 'nough for that rig, the PSU can be getting hot, but still, if the connector melted on the previous motherboard and its likely to do it again on this thing, get a new mainboard mate!

[edit] true roadkill, however if that was the case he shoulda learned from his first mistake.

well I mean like the wire its getting hot and the connector. See since the CPU is requiring more voltage I figure that its to much for the 4 pin power cord to handle causing it to overheat.

You still haven't answered our questions, yes your hypothesis's are valuable and all... but you need to give us info....

So which wire, which connector, be specific man! Does it happen at idle? Load? Gaming? What? And take a pic of the wire and it's gauge... Hot leads mean that the wire has more amps than it can handle causing heat.... and fires

Its the 4 Pin ATX connector to the motherboard that supplies extra voltage to the CPU. And it happens when the CPU is at load. The wire turns kind of hot and the 4pin connector turns really really hot. It gets soo hot that it makes the connector that its in on the motherboard turn hot too. Here is a picture:

Your wire isnt going to get hot unless there is a short. Is it a specific part or the entire wire?

Doesn't wire get hot simply if there's too much current going 'through' it with respect to the wires gauge / insulation? That's what I thought A short isn't the only case where wire gets hot.

It might be quite a sensible idea to stop overclocking everything and go back to stock speeds. Does it still get hot?

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 meant hot to the point where it will melt a molex

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?

Duh!!! Of course

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...
