Sparkle is not happy about admitting it was there psu that caused it, but i do beleive it was just a bad connection. Sparkle at this time says they will replace my 1250 psu, but i,m not sure if i even want it, this is the second one that this happened too.
I have emailed antec and they haven't answered.
Bad attitude, if you ask me.

And I don't believe anymore that it's the extension's fault, it's either the PSU or the MOBO that started everything. I've been avoiding using the computer, actually I haven't used it at all, to avoid a fire.


I hope antec at least show a little respect and reply...

So let me get this straight. You've tried 2 PSU's on the 8 pin motherboard (CPU) power connector, and both of them have had trouble with half of those pins. If I'm summarizing two people's problems into one, oops.

If I have that right, you DEFINITELY have an issue with a physical connection. The question is which one.

That problem may or may not be in the plug, the socket, or the solder points on the board.

(if you're using an extension like it would appear - the QA on those is very suspect - I've had one where the connectors were so crappy, the computer would power down if you bumped it! I QA them myself now when I have no choice but to use one)

The fact that you've had the issue repeat with multiple power supplies seems to rule out anything on the powersupply side.

That leaves the motherboard side to figure out.

I've seen this problem happen with non-computer related connectors before - for example, a vacuum cleaner (what it is isn't even relevant) where the screw on the "hot" wire in the plug was slightly loose.
Even though we were well within operating limits, the slight resistance present on the blade/screw connection heated up the blade, which heated up the plastic, the wire, and the outlet, damaging all three. Upon disassembly, the source of the problem was evident.

If you have a solid connection but too much current - the following can happen:
A friend and I (not sure which of us did it) plugged in a floppy connector upside down - when we powered the computer back up, the insulation on that section of cable (it was daisied off of a standard 4 pin "molex" line) that was thinner (floppies don't need as much power) got so hot the insulation caught fire and fell off (and the wire was starting to glow!) all before we were able to hit the power switch (he hit the switch at the same moment I yanked the AC power cable).

I think i did state in my earlyer posts, this happened with 2 different high end mobos, and with 2 sparkle psu,s. the first was a 1000watt gold, now the 1250 gold, the first one melted everything includeing the mobo connector-this one only blacken the mobo pins but as u can see in the pic melted 1/2 of the psu pins. And yes, i am almost %100 sure it is a bad connection, but yes it is on the psu end not the mobo and not the extentions i have tried.

There's a lot of posts to keep track of. My fault.

So if it's two different boards, and two similar PSU's then I'd also lean towards the PSU connector. Take a look in the end, do the connectors look like they're not formed properly (the square shape)?, how about if you pulled one out, is the connector crimped properly to the wire?

It doesn't hurt to check. If they're OK, you could try "tightening" them up, but if you do be careful, it'd be easy to ruin them, and the MFG wouldn't like it. In cases like this I like to keep an IR temp gun around so I can spot problems early.

Yup, sometimes it is hard to keep track when scanning threads-it happens to me too,lol. But yes, as soon as i get the new one, i planned on takeing a very good look at the connection ends, the bottom row of pins on this one seem to be fine, but the top row are to damaged to be able to tell how they were.

Well i think i,m going to void the warrenty and take the psu apart. Sparkle has desided to play email tag with me and i,m not happy. The last email they sent stated they wanted me to send the psu and mobo to them so there techs could test them both. They were clearly told both still work, but ASUS had already agreed to replace my mobo and i did an advanced RMA with them. So i told sparkle i will no longer play this game, there psu failed as the first one did, they have a 5 year warrenty and there suppose to be gold class also. So either honor there product warrenty or refund me the cost.

I will see what there responce will be, i will post it here to let others know. If it is no, than i will take it apart attach a new 12v connection put it in one of my other rigs and stress the hell out of it to see what happens. I do beleive it is there end connectors are faulty. 1 psu, so be it, but not 2, i have been building systems for over 13 years, i know better.
