Have I damaged my SLI motherboard, PSU or both?

[davidflynn12]

I was swapping out my PSU and inadvertenly plugged the ez_plug as well as the ATX plug into my sli motherboard which is using just the one graphics card. Would i have inadvertenly damaged the mobo,graphics card or PSU doing this?

In order to test the PSU does one need one of does specialised testers. I simply installed the PSU, turned on the rocker switch and using a simple voltmeter/multimeter tested the majority of pins on each plug using the com pin as ground?

1- EZ Plug and ATX 12V at the same time cannot hurt anything

Thanks for the update. What is meant by step 1) in that procedure:

Unplug the leads to the case switch at the mobo and jumper them with a small piece of wire. Now turn on the main power switch at the back of the PSU. If nothing happens, we're a long way to proving the PSU is dead.

Is this the sytem connection panel which houses the case switch, reset button and LED indicators?

Ask the author or wait until someone who has done it replies.

HDD & PSU replaced and PC working, system ok?

The connector is for LED which can be installed in the door. I twisted ALienware's arm to answer this. On rechecking my system connection panel, i discovered my pwr switch connect was wrongly connected into the wrong slot(my fault)!I installed a new hard drive as well and my system now appears fixed and stable. I am hoping the inital problems with with system resets, usb connections and damaged file segments on HDD were to do with either the PSU or HDD. I hope the mobo is unaffected( i hope so the warranty ends in january). Any suggestions to ascertain if i need to check anything else would be helpful?

Just install and run on HIGHEST settings any recent game.
