Yet another one crashing

I am at my wits end here.

Started with a new cpu and a gtx780. Crashed under having been under load for a while. Oh well, I thought. New PSU it is. Going from a 700w ocz is no biggie. Crash again. Oh well.. Boxed fans are shite, toss a corsair 75 in there. Crash. Go from win 7 to 8.1... Why not. Crash.

So I went shopping big time.

Current setup :
Mb: Asus z87 pro.
Cpu : i5 4670k with corsair h75
GPU: 2x Asus gtx 780 direct cu ii oc (yeah. Splurged a bit).
RAM : 16gb Kingston Hyperx beast 2400mhz
PSU: cooler master v850.

Overall decent airflow and no noticed heatspikes...
And for those tempted to suggest the v850 can't run two 780 in sli, it should be, and I have ofcourse tried to run the system with a single card..

Tempted to put my olde amd 720 and gtx 470 in the box just to be able to ramp up a bit of bf4 without having unannounced and instant pc reboot after 5 to 25 minutes .

Suggestions?

Aye, well. Clean install of new os. On new ssd. Old ssd formated. GPU and chipset drivers followed. Everything is clean as a whistle.. I am starting to have suspicions about the Mb being off somewhere, but right now any suggestion is of course a good one

Nope, I figured it would be a dead end as I also went from corsair dominators (8gb 1333mhz) to the ones mentioned above in the process. However, it has occurred to me that it could be my new Mb not being to chipper with either of the sets, but not quite sure how to test for that

dl memtest 86 and you will have to let it run for a few hours
3 passes should be suffiecient
http://www.memtest.org/

before you do that though can you take out the 2nd 780 of your setup? physically take it out and play a game and see if it crashes

do you have the memory set up in dual chanel... slot 1 and 3 or slot 2 and 4?

Second 780 has been out a couple of times during the process (also switched them around to check for faulty card).

Will run memtest overnight and follow up with some folding to test GPU while at work, and an evening of stressing the cpu.. Just got to keep reminding myself that this is supposed to be fun.

New primary is a crucial 240gb of some sort. Old one is a ocz 120gb of some other sort. + two 1tb barracudas for good measure. And crash only happens some time during load, but only tried with bf4 and 30 mark so far.

What really makes this difficult for me to understand is that the instareboot happens very inconsistently in regards to runtime...

If the various testing does not reveal anything, I'll set up a completly independent environment and test components (outside of mb and cpu) independently to try and provoke a similar shutdown. Hopefully. Just posting here hoping someone will mention something that is either beyond the realm of my knowledge or so superiority simple that I'll kick myself into the next world for having missed it.

Thank you for all the good suggestions so far!

if the 30 mark is on your ssd try unplugging the 2 barracudas and see if it still crashes (believe it or not it does happen to cause crashes and artifacting sometimes)

also did you clone the old one to the new one or clan install?
