PSU 24 pin won't plug into motherboard?
 

More problems: building my girl's computer, and I'm going to plug the PSU 24 pin (20 + 4) ATX connector into the board.

It won't snap in, won't even go more than half way in.

The board is a Gigabyte DS3 965G, and the PSU is one I've used in previous builds.. Powerstream 520W..


http://www.newegg.com/Product/Produc...82E16813128018 is motherboard

http://www.newegg.com/Product/Produc...82E16817711002 is power supply.

The ATX 24 pin is a pretty standard thing, isn't it? Any ideas why they won't plug together? Bent pins? Would I be able to RMA the MB/PSU because of this?

Any suggestions at all? Feel bad with my girlfriend's computer half-built..

If they're the same amount of pins (24 prongs on mobo and PSU) then it's definitely bent pins. Same shit happened to me a few days ago and my thumbs ended up blistered trying to fix it. You have to screw around with each pin until it goes in there. Try pushing it down at an angle.

Oh, and you know that the 20-pin plug on the PSU goes into the 24-pin socket on the mobo right? There shouldn't be anything in the last 4 prongs. The 4-pin PSU cord goes into the auxillary slot beside the CPU.

Bent, or something inside one of the connectors. I'd say you have it reversed but it wouldn't go halfway unless you sat on it.

Use a flashlight.

Sounds like you're beyond this but just to make sure (newegg's pictures are inconsistent)...

This is a 20+4 combination:

These blue connectors are the 4x4 aux connectors Lasereth mentioned:

20+4 provides the extra +12, +5V, +3.3, and a ground while the 4x4 aux provides two +12 and two grounds.

Yea I've got one of aux plugged in fine, and about the first ... 10 or so of the 24 fit in fine.. its somehwere in the middle, towards the end where the extra 4 slide in.. :( guess ill try some bendage tommorow..

Thanks, all

Yeah it's definitely the bent pins from your description. I used a safety pin to bend the pins until they fit perfectly on mine.

Is it possible that it's the connectors on the 20+4 cable itself?

I can't decide if the pins are bent (they don't look like it) or if their little copper "covers" inside the cable itself (look closely in this picture: http://images10.newegg.com/NeweggIma...711-002-09.JPG) are the just off...?

On mine it was the copper covers AND the copper pins bent. They weren't even noticeably off either -- it was like 1 millimeter or even smaller.

If I had a guess I'd say the contacts within the male PSU connector are out of alignment. A lot of plastic molex connectors have this problem. Try shifting the wires around a bit and then see if you can slide it in.

Either way, an inspection of either end connector should tell you what is bent and what isn't.

No way man, it wasn't obvious at all!

Just spent 6 hours with a flashlight peering at both the male on the motherboard and the female on the plug, and they looked PERFECT. I eventually go it to the point where two other power supplies I had could plug in, but not the new one.

After all that time fiddling with the safety pin (excellent tool choice, btw.. couldn't figure out what to use until you mentioned it) I finally got the motherfucker to plug in.

Got windows up and running, but now it's telling me that my ethernet cord is unplugged when it is clearly not. What a damned nightmare..

Sounds like fun. :) The joys of building computers. Check and see if the router and/or modem is fully functional and try a different cable. If neither of those work it pretty much has to be the actual NIC.

Windows + Break, Hardware tab, Device Manager, see if your ethernet/nic/network junk checks out.

Ethernet drivers were fine.

Was the cable.

Shits finally up and running.

Thanks all.
