Power Supply [Need feedback]

[kerovi]

Hello, I've bought some parts for my new build.
RAM: Patriot Viper Extreme 8GB @ 2133MHz. (2x4GB)
MOBO: Asus Maximus IV Gene-Z
Graphic Card: AMD RADEON HD 6990 4GB
AMD Radeon HD 6990 Graphics
Processor: Intel Core i7-2600k

And the question is: I currently got unboxed 600W modular power supply, will it hold my setup? I don't really want to risk my graphic card from being damaged. And I do NOT use Crossfire, only using single GPU.

Need feedbacks/your opinions please. Thanks in advance!

Can you tell me how did you come up with that?

You're on the edge of what your PSU can handle.

I recommend trying some benchmarks at stock settings, no overclocks, if the computer turns off, your PSU can't deliver enough power to the GPU.

PSU calculator. You can probally run this at lower (700+), but 820+ is reccommended due to capacitor aging and such.

Why would you run a 6990 with only one of the gpus enabled? Just curious.

What do you mean bro? It has 2 GPUS inside? I got this card as a gift so explanation would be great

Yes it's a dual gpu card. : ) You're lucky to get that as a gift!!! =D Games need to support crossfire though, otherwise it will just use one gpu.
