hi, yes it is an immediate reaction when the GPU is used
when i use GIGAPIXEL using only CPU it works, when i activate GPU , PC shut down on the spot.
With video games, if i up the settings 1 by 1 (shadows, aliasing, ...) same result.
Using Heaven Benchmark 4.0 it work for the first test, and same result when trying GPU stress test.
My pc is a monster x2 SSD 1 TO into my motherboard. x2 Classic Hard Drive 2TO
many USB device connected (4to x2 + on rack) , a scanner ...
cable connection on the GPU are ok, i can't mismatch anyway. Only one way to connect them.
i just order an -ATX Seasonic G12 GC - 850W- i think and hope it will be ok
i need this computer to be a rock-star for my work, i do not care at all about games, i use them to test my problems.
