Powercolor HD4850 crash

[HawkEye1]

Hello, I bought my graphics card (Powercolor HD 4850 GDDR3 512M) 3 days ago. So I'm mounting as usual, installing the correct drivers. I have a surprise. I see in the ATI CCC that my temperature is 78 degrees idle. After research, it seems that it is normal ... Short, and I run stalker ... its march but once 2. (although its no longer works at all) Just after loading the level, I have the right of a pretty graphic artifacts (fraction of a second) then the screen light turns orange. I re-boot and the desktop switches to 16bit. (Same for the game trackmania).

So I wanted to know if it's because of the temperature, although its is normal, or a supply problem (Blue Storm Fortron 400W v1).

The power supply cable is not plugged into the graphic card either forgot to save (which I doubt) or your power supply is not powerful enough

I actually think that 400 watts is just good. I have a 520 Watt from Corsair for SLI and no problems with HD 4850

Finally, although I had not seen your config signature when compared to your configure the food should be sufficient. You plugged the 6 pin PCIe?
