New PSU-Won't boot

[alphanumeric]

Afraid not. It's an i7 920 and it's only just over a year old. Before changing the PSU it was working perfectly.

You have no idea what the PSU might have fried when it failed. Like I said in my first post, it could have very well toasted a component or two on the motherboard, to include the CPU or anything else.

It could also have been the other way around. A motherboard/CPU failure could have taken out the previous power supply. The new one likely has overload and short circuit protection to prevent it from going up in smoke. This is just an educated guess on my part. Possible multiple failures can be a real pain for the home builder with limited spares to trouble shoot.

John. As I mentioned in my post #40 and Phone Man mentioned in his post #59,
I would take the time to swap out the new PS with a known good one. This will
at least nail down that weather it is the cpu/mb, or a bad NEW PS/ or Incorrect
cable attachment.
As Dwarf pointed out, the plug-ins on that Corsair PS are very confusing at best.

I'll have a look around to see if I can find anything on AX850s and GA-EX58-UD5P/UD5 Motherboards, and how they are connected.

I have not been able to satisfy my quest.

This fellow (RAM GUY) seems approachable if you continue to have problems.
I offer a link to one of his replies on AX850 24-pin cable question - The Corsair Support Forums See post #2.

Sorry to jump in late. Hope this might help:

On the 8 pin ATX/EPS connector there is usually a tab and groove that allows you to detach or combine the two 4-pin connectors. You slide them up and down against each other to connect/disconnect. You should have one 8-pin plug to work with. You normally do not plug each 4-pin plug individually. If you do, the tab may spread the plugs far enough apart that it will not make good contact.

The Corsair website has this diagnostic (image below) to test the supply for proper startup logic. This will let you know if the issue is with the case switch or connections.

Hi folks. Thanks for all your posts whilst I've been away
I'm still no further forward with this. I just tried unplugging everything except the mobo and still got the 89 error and no post.
I'll attach a picture of what the LEDs on the mobo look like. They look the same with or without other items plugged into the psu.
I've looked at the Corsair site and performed the paper clip test on the psu. This indicates that the psu is good.
I am still concerned about the tiny front panel headers. When I built the machine it wouldn't post and it was a problem with the way these were connected. At the moment I have a power button that works plus 1 blue LAD on the top panel. The rest switch doesn't work but it never did before.
This is what the LEDs on the mobo look like with or without everything else disconnected. I'll also post a pic of my socket arrangement with all plugs in plus the front panel headers that were the problem before.
To be honest I'm at the point of giving up with this. I don't feel up to taking off the HSF and reseating the chip. I can't even tell if it is the chip. If it is either the chip or the mobo I cannot afford a replacement now anyway.
There is a good pc builderr/repair shop near me. If I took it in there do you think they would be able to diagnose my problem for me?

Just a suggestion if you haven't already.

Disconnect the front panel switches and use the on board.
Shown in Snip.
Power and reset circled in yellow.

That would eliminate the front panel switches temporarily.

 

[johnwillyums]

Think I already tried that. Without those headers in it won't post at all. That's the problem I had when I first built it, I left them out deliberately to eliminate any issues and they were the issue.

 

[Hopalong X]

It doesn't give any info on operation.
It just shows where they are located.

 

[johnwillyums]

No I mean the little front panel headers. They go into a box on the bottom right of the mobo. There's a picture of them in one of my earlier posts.
I'm gonna try one stick of RAM at a time so I have to switch this machine off for a while.
Back in a bit. Thanks for your help

Hi John. Can you get into the BIOS? If so, go in and choose optimized default settings. See what happens there.

Also there guys are very good Tweaktown's GIGABYTE forums. Maybe wazza or Lsdmeasap can provide an answer for that code 89 you're getting.

Also do double the connections from the PC case to the motherboard. Also make sure the ATX12v connector is correctly connected, that is the 8-pin connector is plugged into the motherboard, not the 4-pin one.

 

[johnwillyums]

Yippee. Here's a picture of me beamong and The Hound of Mystery looking happy.

 

[sygnus21]

@ johnwillyums - I took the liberty of posting part of you issue over here to see if I can help get you an answer - Error codes 69 & 89 on EX58-UD5. Between us and them maybe we can get you fixed up.

Later

Edit - so does that mean the problem is solved???

So it was your ram? Or was it the scary picture?

 

[johnwillyums]

Unbelievable!. I went through each stick of RAM one by one in differenht sockets and nothing.
Just on the off chance I moved my DVI connector to the other socket on the pc and the other socket on the monitor and bang! It works.
Not sure how this has happened. Perhaps it wasn't fully in or I have a duff DVI either on the PC por the monitor.
I am so relieved. I was just about to give up and would have had to leave this pc for months before affording a new CPU or RAM or anything.
I can't thank you all enough. Reps all round. I certainly would have given up withoiut your support.
Can't quite believe it

 

[Hopalong X]

It is always the stupid little crapola that gets you.

Glad it is running. Never would have thought about that.

I can imagine next OP that posts with a possible PS issue.

"First check your DVI connection and cable"!!!!

 

[DocBrown]

Been following this thread & it had me stumped

So expect the un-expected

 

[Dwarf]

Yikes! That's one scarey picture!

Glad to see that you have resolved your problem. A most unusual solution, but we should all be aware that, should anything go wrong with our computers (and sooner or later it will), we might have to look at the least as well as the most obvious things in order to resolve the issue.

 

[sygnus21]

It's always the simple things that get us

Glad to see you got it fixed John.

Peace

 

[gazz9496]

that is one bizzare solution, glad you got your pc working though

 

[jfar]

Great news that you got sorted John, well done on solving the problem by yourself and the dog.
