Furmark is *VERY* demanding for graphic cards. To be honest, it will stress out your cards further than any realistic program. As such, some components cannot sustain the stress and fail. Video cards could fail (temperature or power draw), PSU could fail...

So, what are the ratings for the power rails of your DELL PSU? (how many Amps are stated for each voltage on the sticker) What is connected to each rail (particularly if you have multiple 12V)?
A full system shut down points towards the PSU, but I've seen video cards do that too.

Conclusion is that if your system works correctly normally, do not run Furmark anymore ;)

ratings look reasonable.

Can you make sure each graphic card is on its own 12V rail? The rail (12V1, 12V2,...) should be printed either in the manual or optimally on the PCIe connector.

Otherwise, it could be either of the 9800GTX. If you do not encounter any problem outside of Furmark, I would just recommend to forget about it and just enjoy your setup.

hi again ive got each graphics card on there own 12V rail
but as ive only got 2 PCIE connectors on the psu ive had to use the 4Pin molex connectors as well but as none of my devices use them that should be ok i would think ?

i could be wrong here
but i am looking at a corsair 850watt psu as a replacement
so fingers crossed its just that

i tried with the OCC on my original mobo and it works flawless my psu didnt turn off either
but now with this new mobo the 780i one
it cant handle it
so maybe its the psu thats at fault
but like u said if its ok otherwise i shouldnt worry
and to be honest i aint worried i just dont want this PSU to go out and take all my hardware with it as well
so replaceing it is on my top priority :)

Really furmark is to demanding and you will never have a game run your card that hard .Furmark has ended a lot of cards because they were just stressed to the max.I use 3D vantage and 3Dmark 11 and if they run fine ,then I know most any game is going to be fine.

well replaced the PSU and Upgraded The Case

and i have to say wow much more stable ive noticed since ive done this my temps have dropped somewhat so i dunno if the power falling under was causeing an heat issue but its certanly fixed the problem with testing as furmark runs now and it dont turn off :)
