PSU problem

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?

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.

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!!!

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.

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?

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.
