I've been getting some crazy crashes lately with my rig. When I have SLI disabled I'll get a black screen telling me that the driver has stopped and recovered. When SLI is enabled I get a black screen and the whole pc reboots giving me the windows did not shut down properly screen. I'm feeling like it may be the PSU but I just wanted to get some other input first.

G.skill 24gb DDR 1.5v 1600mhz

Cool man. I also got this http://www.thermaltake.com/products-model.aspx?id=C_00001777 do you think it'll help me test the PSU appropriately?

Not sure if that tester actually puts a load on the PSU or not....

Dear Sajin,
i would appreciate your valuable input solvoing the Nvidia Drivers issue on a 4SLI configuration.
I am EVGA enthusiast since many years and i am always making SLI builts since SLI introduced.
Now here is the issue:
With allways the latest Drivers installed, even though the nVidia control correctlly recognizes the 4 470GTX GPUs on board,
when i use the 4SLI bridge, the nVidia control panel sets me up with 2Way SLI and requests me,
to connect the sli connector to maximize perfomance. At the momment i am using the 3SLI bridge in order to get
the 3 Way SLI with the forth card not interconnected (For your information, Drivers automatically use the no2 card for Fyzics produsing
a considerable amount of heat between the no1 and no3 card, pls keep in mind that the Cool Laboratory Liquid Ultra perfomace thermall compount is used
to all of the cards and a slim exhaust fan is installed out of the case to help the cards heat dissipation i am allways running below 80c with ambient temps at 21-25c at all
stress tests and games and i am happy with that).
Do nVidia drivers  configure the 4Way sli automatically? or there is a special trick with the Z87 Classi?
Anticipating your input.

470's only support up to 3-way SLI. http://www.geforce.com/ha...gtx-470/specifications

Dear Sajin,
Since now planning upgrading GPU's, what would be your choice for an affordable 4sli capable upgrating?
