24 Pin P1 Connector Wires getting extremely hot

[segalaw19800]

Yeah, I wouldn't be too happy to learn it that way thou. Makes me think about the bad capacitor thread. :shadedshu

ha aha ha I love that thread..

Haha same here. Learnt the hard and expensive way oh well.

 

[Radical_Edward]

Yeah, that thread makes mad me worry about my overclock, so I went and checked every cap on my mobo for heat/future venting, none are more than slightly warm. Should be fine.

Threads like these do give me second thoughts but what the OP has done is way more dangerous than what im doing. (Overclocked 930 to 4ghz) which by the way, almost every 930 owner does

i'd have to agree with the others opinion, that by using green edition cards you're forcing all the power draw into the one set of 12V wires and overloading it.

some motherboards come with molex/floppy power connectors near the PCI-E slots to prevent the situation you've having, and spread the load out.

So if Asus were to not accept my board for RMA, should I give up??

I wondered what the floppy connector on my mobo does. thx

if they don't then there is still some hope if your good with the soldering iron or know someone that is. If you/someone could replace the 24pin on the board then it "should" work fine again.
maybe replace it with angled one to help with WM while your at it.

Iam a JStd001 Certified Soldering Tech. and do soldering on oil drilling tools.

I use a professional Weller WSD1000 and Metcal Soldering stations at work...

I can do that soldering but the availability of the socket locally is the issue.

Just take one from some old useless mobo with 24pin connector.

Fight with ASUS to the end. It is a clear flaw in their design and they should replace the board. They obviosly know the problems with pulling that much power through the 24-pin connector alone, because some of their other boards with 4+ PCI-E slots have extra power plugs for molex connectors to help power the PCI-E slots, the Rampage III Extreme actally only has 4 PCI-E slots and has two molex connecters that they recommend you connected when fully loading the slots with cards. So for the P6T6 having no extra power connectors and 7 PCI-E slots just seems like ASUS asking for exactly this situation.

he wont get anywhere.

normal users use video cards that need PCI-E connectors.

normal users dont fill all slots with video cards - they use them for other things (soundcards and what not)

normal users dont run a video card in every slot and load the system (GPU + CPU) 24/7

they'd just tell him he's using it in ways its not intended, get video cards with PCI-E power or stop folding.

 

[Chicken Patty]

Mussels is right, but Maybe he can just say he only uses one card???

 

[Laurijan]

They would propably say its the PSUs fault or something if they want to be bitchy.

 

[Chicken Patty]

He can show them the RMA copy or something. He did RMA it right?

Yes, but normal users don't buy workstation motherboards with 7 PCI-E slots designed to accept graphics cards. If the 7 slots were not meant to hold graphics cards, then they wouldn't have used physical x16 slots. They would have made the x4 slot a physical x4 slot, and the two x8 slots physical x8 slots to prevent them from being used for graphics cards, this would have still left 3 x16 slots for graphics. But they made all those slots physical x16, the only reason to do that is so they can accept graphics cards.

And it doesn't matter if the cards need PCI-E connectors or not, the board should be able to supply 75w to each of the 7 slots regardless, that is the PCI-E spec, doesn't matter if it is a video card or a sound card or a RAID card, each slot should supply 75w. This board obviously can't without melting the 24-pin connector, so it is a manufacturing/design flaw.

And even cards with PCI-E power connectors draw a lot of power from the PCI-E slot, they don't rely entirely on the PCI-E power connector.

 

[Laurijan]

What is better - RMA the board and say it happened under "normal" circumstances or RMA the board and start a rumble about PCI-E specifications and design flaws?
Obviosly you cant do first option and then if that doesnt work second option.

I told the retailer that I used two cards. Its designed for true 3way sli with 2nforce200 chips though. The tech in the shop told that they had a similar case on P6T6 Supercomputer mobo and Asus did not honour the RMA saying it was the PSU or the Power Line fault.

Just what I said!

Asus doesn´t want to use it´s brains to figure out what could have caused the burned socket and just thinks in so simple terms (what comes first into their mind).

But lets still hope that you will get a replacement.

 

[Chicken Patty]

Shiv, what will you do if you get a replacement board? You still going to try all the cards again?

Nope.:shadedshu

Will go for two cards first. 9800GT Green and one 9600GSO Non green. If everything goes fine, gonna go for one more 9800GT Green.

 

[Chicken Patty]

K sounds like a plan

 

[OneMoar]

replace the motherboard that is a major hazzard to you're home and you're pc

Guys,

I had a Corsair TX850 burn out its wires on the 24 pin P1 connector. The wires especially of the 4pin connector that comes along with the 20 pin connector. The insulation on the wires just burnt off. This was powering 6 X 9800GT Green cards. I know it was overloaded. So I RMAed the PSU and got a new one yesterday. The strange thing Im noticing is that though its powering only 2 9800GT Green Cards and one 9600GSO card which is powered by the 6pin PCIe connector, the wires on the 4pin connector tht goes to the mobo are extremely hot to touch. The cards are folding 24/7 full throttle.

I dont know wht I'm doing wrong. Seriously I don't wanna RMA this PSU as well as I had to fight with the retailer to get him to accept the PSU for RMA even though Corsair agreed to replace the first PSU.

I forgot to mention...The P1 socket on the mobo was slightly burnt and there were charred remains inside the holes. I used a wooden toothpick and some compressed air and cleared out the mess.
But could this be a reason?

On my primary system, I have 2 9800GTX, 1 9800GT, PCIe sound card and PCI Tvtuner card all powered by HX850. Even when folding on all cards, the wires on the 4pin connector are warm to touch.

Cheers,
Shiv

you can also find a fucked up mobo and salvage the 24pin connector from it and weld it to your mobo. should work good as new. if not, try replacing the caps connected first to the burnt out pins(you can do this by tracing the circuit on the board). this is beacuse its possible thats the caps that are connected takes the brunt and saves the rest of the mobo.

this is what you get for buying asus junk
