PSU problem

[The Apathetic]

Hello,

I previously posted that my new OCZ 600W broke down my old MB, once I plugged everything and started up, the MB LEDs started shaking, the CPU and GPU fan went crazy (they were much much faster than usual) and finally 3 ram slots died...

I changed the PSU with an identical 1, bought a new MB, bought a new GPU card, plugged everything in and.... the LEDs were shaking, the CPU and GPU fans went crazy.. luckily nothing died on the new MB..

Before I bought the PSU, I saw it working with my own eyes on a different PC (however it should be noted that that PC was much more powerful compared to mine, specs were High)

So, could some1 explain to me why this PSU is acting like this with my pc?

 

[bobkn]

Explain? Not really, based on the limited information.

Sounds like it may be time to test the motherboard outside of the case, using minimal components (RAM, graphics card, one HD, one optical drive, no additional USB devices, etc.)

It could be something as simple as a short circuit to ground due to an error in placing one of the motherboard's mounting standoffs.

 

[The Apathetic]

Done, same result..

If the info are not enough, please let me know what else should I add ..

Sorry to hear that.

I guess you might have to go further: disconnect all drives, install only 1 stick of RAM, and see if you can get into the BIOS settings.

Is there a chance that your CPU was fried, along with the first motherboard?

Bob:

I was on the OP's original thread. He seems to think he has 3 dead RAM slots, but I don't know if that has been confirmed. I asked him to try memtest. Two PSUs yielding the same behavior would imply motherboard or RAM.

Wannabe: are you satisfied all of the connections from PSU to motherboard are proper and intact??

Are you satisfied that you have the right RAM for that board---particularly that the RAM is the correct voltage?

Have you been attempting an overclock?

No, thank God, the CPU is still intact..

I tried connecting only 1 RAM and still the same result, nothing shows on the screen, all fans are going crazy fast, etc...

I tried different RAMs on that motherboard (my original Microns and 2 others) still nothing..

Everything was installed correctly, I'm 99% sure.

And this is all the info of my RAMs that I use on my current MB (which also acted crazy after connecting it with the PSU but thanks to God, nothing happened to it)

Never tried to OC on the old MB.

2 different mobo's,2 different psu's, same problem? sounds like user error somewhere along the way, double or triple check all power connections ,check for shorts etc i know of one person who actually cut off the location tab on a connector because it would'nt fit the way he wanted it to!!!

 

[ignatzatsonic]

Yeah, I think pebbly is on the right track.

Wannabe:

Identify a stick of RAM that you know is good. Don't attempt to use the other sticks. Set them aside.

Here is your manual if you don't have it:

GA-EP41-UD3L (rev. 1.0) - GIGABYTE - Support&Download - Motherboard - Manual


Here is a picture of your board.

Tell us where you are connecting your cables from the PSU to the board.

Tell us what single slot you are attempting to use with your known good RAM stick.

 

[The Apathetic]

Well, the only thing that I noticed when the guy at the store was trying the PSU on their computer was that he plugged in both 4-pin CPU cables into their MB, my MB only needs 1..

Could that be possibly the problem?

 

[ignatzatsonic]

Refer to your motherboard manual for proper connections.

The connections required on the store's motherboard has nothing to do with your situation unless that board was identical to yours and I assume it was not.

 

[pebbly]

can you try a wired kb and mouse just to eliminate cross channel interference just a thought?

 

[The Apathetic]

Yeah, I think pebbly is on the right track.

My EP41 is the 1 that didn't have any damage, the 1 that was damaged is GA-P31, the only DIMM that is working is DIMM4.

I highlighted where I connected the PSU and the working DIMM in the following picture>>

Everything was connected correctly, I didn't force in any cables or anything, everything just went into the MB smoothly like how it's supposed to be..


@peb Actually I don't even use the WL KB+M anymore, I'm all wired now, better go update my specs.

 

[ignatzatsonic]

If I understand you correctly:

You have the model 41 board and as far as you know it is not damaged?

Does your manual say you made the correct connections as shown in your diagram?

 

[pebbly]

clear the cmos by using the correct mobo jumper ,load bios defaults and see what happens , you could place a sheet of A4 paper between mobo and outer case to eliminate shorts

 

[ignatzatsonic]

Confusion:

You say in post 12 that only slot 4 is working.

What makes you think that is true?? How can you prove that? What makes you think you have ANY good slots?

 

[pebbly]

on the ocz 600 the main 20+4 connector, are you using the correct 4 pin connector there a 3 different 4 pin connectors on that psu all should be identified

 

[ignatzatsonic]

Pebbly:

I think that may be it. He needs to connect the 20 of the 20/4 to the only 20 pin port on the board and to connect the square 4 of the 20/4 to the only square 4 pin port on the board. I hope he is simply using the wrong lead from the PSU.

I looked at the OCZ manual and it doesn't show the cables--only the connections on a mobo. So if there is another similar looking square 4 pin leading out of the PSU, that may be what he has mistakenly used.

But I don't know yet why the OP thinks he has good or bad RAM or good or bad slots.

The mobo manual says a single stick should go in one of the yellow slots (1 or 3)

hi ignatz , he does need to connect all 24 pins ,the 4 pin connectors should be identified as power,cpu and pci-e they also should have foolproof configurations to suit the different 12v power rails

Pebbly:

Here is a pic from OCZ site for a 600 watt PSU. As far as I can tell, it is the ONLY 600 watt unit they make, so I hope this is it:
