24 Pin Connection Problem

post #1 of 9
Thread Starter 
Hey guys,

I"m having some issues with the 24 pin connection on my TX750M. It seems that the metal "pins" on the inside of the 24 pin connection keep getting pushed down. This is causing my computer to shut off randomly. When it shuts off or when I turn off my PC some times I have to push the 24 pin connection into the motherboard or move it around a bit until my PC will boot. I know it's an issue with the 24 pin connection because I can see that they are getting pushed down every time this happens and I've tried another motherboard with the same results.

I can push the wires back into the connection head and they do move back up but for whatever reason they are not staying there. I think I need to pull the entire power supply out remove the 24 pin connector and try to do some kind of fix. Problem is I don't know if this is doable and I haven't had much luck finding anything on the web about it.

Can anyone point me in the right direction or help me out?

With the connector removed from the motherboard, try pushing each wire into the plastic body because maybe the pins aren't latched to it.

Yeah, I've tried that. When I do that and plug it back in the PC will boot fine. But, after a while the PC will shut off randomly and then when I pull the connector back out the pins are pushed back down again.

I say talk to Corsair about RMAing your PSU after all that's a physical defect with the connector. Alternatively you could connect and fasten a 24pin extension to the factory cable and connect that to the motherboard.

Have a couple of pins that are loose in the ATX connector but hold to their mates when I do something about it
Unplug power from the wall
Lay computer on side
Use tweezers to push down each of the offending pins ( should be able to easily see which one's you need to work down )

I would really hate to RMA it. That would leave me completely ouf of a PC until I got it back. Unfortuneately I don't have the extra money right now to do an advanced RMA. I guess I could deal with the problem until I am able to do that but would rather not.

The extension cable doesn't work the same way as the connection to the motherboard? Just curious as to how the extension cable would fix the problem.

I think they need to be pushed up rather than down but I don't know it's difficult to tell. I do know when I grab an individual wire there is tons of wiggle room for it to go up and down so that's obviously an issue.

Frankly I'm confused about which direction you mean by "down" because it's normally a sign that the PSU pins are making good contact, but when the pins are being pushed up (by the connector on the mobo), it indicates they're not. I also don't understand how PULLING the connector back can PUSH the pins down, rather than pull them up.

When the 24 pin connector is connected to the motherboard I can use a pair of tweezers and push the individual wires back into the connector towards the motherboard. When I do that the system will boot and stay stable for a while but for whatever reason they start to lose contact again after a while.

First of all, do that only while the power is off because when pins make contact, they arc and form carbon on them.

I think you should remove each pin, one at a time, and try spreading out the two ears on the sides by using a jeweler's screwdriver. Spread them only slightly, and it would probably be a good idea to clamp them just beyond where they attach to the pin body, to prevent the ears from breaking off when you bend them.
