Sleeved my PSU, now won't power up....

[goobernoodles]

So... I got a bunch of stuff to tidy/silence my system yesterday... and so I got to work on the PSU. I sleeved the main 20+4 pin motherboard connector, one string of molexes, the 4 pin motherboard connector... and a bunch of other crap. Now it won't power up.

I labeled each wire before taking apart the motherboard plugs, however a few rubbed off...

I'm 85% sure all of the wires on the main 20 pin section are correct. I have a little bit of doubt that the 4 pin P4 atx power connecter is flipped around... There are two yellow wires and two black. If one yellow wire is in the other's position... will it still work? This goes for everything, theres multiple orange, black and red wires.. off the top of my head. I think the 20 pin plug's are in their original positions, but the 4 pin might be out of place. What would happen if one of the wires of the same color is in a different position?

Anyways, pics on request.

^says it all. lol

I'll clarify on how.. they rubbed off. I couldn't find any masking tape, so I had to use duct tape.. and duct tape + sharpie = not great...

soz, dont have an answer but loving the pic

What would happen if a wire of the wrong color is in the wrong slot? That would be connecting the ground directly to a live wire. Say goodbye to your hardware.

maybe that will help

"To test the power supply, you can do this: Unplug the power connector from the motherboard. Connect the green and black wires on the power connector with a paper clip or a piece of wire. This will energize the power supply. Now, using a multimeter, the 12V should read 12V, the 5V should read 5V and the 3.3V should read 3.3V (within +/- 5% per Intel specifications.)"

Cubby - What I meant was what would happen if say.. two orange wires were in the locations of orange wires, but were not the original wires there.

 

[goobernoodles]

I don't have a white wire... There never was one... The hole was vacant when the thing worked.

 

[goobernoodles]

And according to that diagram, everything is connected correctly.

 

[cubby1223]

All wires of the same color are of the same voltage, that's not a problem. And a lot of PSUs do not have the white -5V wire, that is not a problem either.

Maybe some of the connectors arent pushed in right and when you plug it on it just crams the metal thing up into ur plug... its happened to me on my hard drive power plug

 

[Fullmetal Chocobo]

I remember last time this happened to someone. Unplug the power from your floppy drive, opticals and hard drives, and try it again. The guy I had helped last time had his floppy power cables mixed up....

 

[goobernoodles]

Ok, I just tried again, and the power turned on for 1/2 a second, fans spun, then turned off..

 

[goobernoodles]

I do have a digital multimeter, and a camera... I could take some pics of the plug.

If you had reversed the 12v 4-pin, the PSU will have survived, but the motherboard may not have.

 

[goobernoodles]

Na, the yellow and blacks are in the correct place. I just may have switched the two yellows and blacks with one another, but that shouldn't affect anything. Right?

I have not put a 12v in a ground position, or anything.

If i were you id pop in another psu right now to make sure you didnt fry your mobo, and id get an old crappy one and shove it in there so in case it does happen, its no so bad.... :/

 

[goobernoodles]

I'll hook up my gf's psu. I'll be back.

 

[Bluestealth]

Strange problem gl

 

[goobernoodles]

Well... I can't seem to get it to start off of my gf's psu. Granted, I only plugged the 20 pin and 4pin in... but the cpu fan did not spin. So...

 

[goobernoodles]

So now I'm starting to think I fried the mobo.

 

[NeezyDeezy]

you swapped the pins on the 4 pin atx

 

[goobernoodles]

Is it possible to fry the motherboard when everything is in the correct position? Its possible that a few wires may not have been contacting, but would THAT fry it??

I would test to see if the power supply worked by itself.

Ok, the power supply will turn on when I short the green and black.

So... I thought that maybe the motherboard somehow was short circuiting, because I had to take it off last night to put on a zalman chipset cooler. This is what I found:

LOL

So last night, after working on this thing for hours already, I must have completely missed the fact that there was a metal molex remover tool on the mobo tray before I screwed it down. Wow.... So it must have been shorting out. I'm going to test the motherboard now, but I don't have too much optimism.

wow.... lol

anyone wanna sell me a s939 board for cheap?
