Hey guys,

Wondering if you can assist me with this issue.

I've got an H1000W from Corsair and my PC was rebooting by it self and sometimes, when turning it on, it would start with and on and off shutdown loop.

I found that in my PSU 24 PIN connector, one of the yellow cable was meltdown, when I took it off, I noticed that black connector that connects to the motherboard was also meltdown...

Thankfully, the connectors/plugs on the motherboard seems fine, only the yellow cable from the psu is broken.

Now, I need you expertise on this, what may have cause this? And when I replace the psu, will it happen again?

I've sent an e-mail to corsair, they started the RMA, which is good news, I just wondering what may have cause this and if It will happen again with the new one.

Maybe the 1000w is not enough for this setup? I can't think of anything else for what may have cause this...

My setup:

CPU: i7 2600k OC @ 4.6ghz 1.39 volts
PSU: Corsair h1000w
Motherboard: Asus Maximus IV Extreme REV 3
RAM: Gskill 8gb 1600 CL7
GPU: 2x EVGA SC GTX 580 SLI slighty OC
Sound: X-FI Forte 7.1
HDD: 1x WD velociraptor 120gb Sata + 1x WD Caviar Black 64b 1tb SATA3
Cooling: 7 Fans (1x140 3x120 3x220 + CPU Cooler: Corsair H100
Case: Coolermaster HAF X

Most likely a manufacturing issue in the PSU wiring somewhere. I wouldn't imagine that it'd happen again, I'd be more worried about damage to the mobo.

Odd are it was just a poor crimp on the wire causing a high resistance connection so when you pulled some current thru it, it got turned into heat and melted.
Was it pin 11 by chance?

thanks for the reply guys,

not sure the number have to check when I get home, but it was a yellow one, the one from small 4 pin extension.

Also I ask for some help/info on what have cause this in the corsair RMA mail and I've got an reply saying:

Dear Sir
That could be a problem with the MB but we can replace just the cable if you like please provide your address.

I'm no electrician expert, but the power comes from the PSU to the motherboard, the cable on the psu is damage, it's more logical that the problem is the PSU and not the MB. But then again, I'm no expert.

except that particular cable isn't one of the modular ones. LoL They need the whole supply back.

Exactly, that's what I've told them, they said to send it back, I've already send it, hope it will not happen again...

The Yellow wire is +12 Volts.

It would most likely supply power for the PCI-E slots or fan headers or chipset.

I would check to see if any fans connected to the fan headers are properly connected.
