i tried many fresh installation of win7 and win8

I'm going for the PSU. Cougar (OEM HEC) is known for bad quality PSUs.

 

Try plugging in your display to your second card and play games on it. If it works, it's your PSU. If it crashes, take the first out and put the second card in the place of the first. If it crashes again, it's the second card. If it works, try the first card in the second slot and try playing a game. If it crashes, it's the motherboard.

no at all
every card runs very good
stand alone only
both of them (even disabling crossfire from catalyst ) will crash and rebooting

will seasonic 850 watt bronze ?
be enough ?!

thanks

Yes that will be enough. I own the 520 watt version for one of my builds and it`s great.

Yup, it's the PSU. A Seasonic 850w is enough for your cards. Happy gaming thumbsupsmiley.png.
