Problem with new MSI Twin frozr HD7950

[stuuk]

Hi
Hope someone can help
Just installed the MSI twin frozr HD 7950 in my sons PC.
Previous card was an XFX 6870 which worked perfectly no problems at all.
MB is Asrock Extreme 4 and Intell i5 3570
PSU is EZCool 700 watt.
Graphics card installed no problem and seems to run windows fine.

Counter-Strike go - After around 10 mins of game play PC suddenly shutdown and restarted as though someone had flipped the power switch.
Prior to the shutdown the fans were quiet and temps 60-70

BioShock Infinate same thing again after about 10 mins gameplay.

The driver is 13.1 off the cd

Should this be rma'd or is there anything I can try?

thanks
Stu

thanks for the reply
The psu has 2x 6 way pcie power plugs off different rails
The card has a 6 way and 8 way pcie power sockets
Plugged one of the 6 way straight in the card and used the 6-8 adapter that came with the card for the other socket
I'm d/loading the latest msi driver now and will also try a jeantech 700watt modular psu i have and let you know
