im in a hurt here, i setup two systems out of 6 yesterday not a problem, bottom of the rack. then today i wired the rest very neatly etc. go to turn on the 3,4,5,6 and first one fire on the vrm under the heatsink next to cpu. 4th same place but caught it before it got bad, 5th i heard a pop but couldn't find anything, 6th a chip on the top of the mb burned a little. This sucks but things happen. i took pics of the mb setup and my pdu. you can see i have the mb's on aluminum standoffs 1" and its sitting on a piece of flashing. the pico ground in on the standoff cause its a round jack for pico power from a pcie cable. not sure what i need to do to fix this possible short? like i said i didnt have a problem with the two on the bottom but then 3-4,5-6 had problems... any help is good help.
