Potential upgrade to 6990?

[Sharp]

I am not considering buying it yet, as I have a 6870 which does all my games smooth. This question is more for maby half a year in the future when there has hopfully been release a 6990 with good enough cooler.

All I realy wanna know is if my power supply could do this.

My rig is:

Intel i7 950

Gigabyte UD3R v2

Chieftec Super Series 650W PSU, ATX 12V V2.3, 80 Plus, Modular

Corsair XMS3 DDR3 1600MHz 6GB CL9

And of course dvd drive and a singel 7200 rpm harddrive

The question is if anyone knows how much watt my sustem takes.

It would be very handy if anyone could try to calculate it as I'm pretty much a noob when it comes to hardware as I had my first desktop which I built myself 1 mounth ago.

As allways much love to the oc3d community for their awesomeness and advice

Regards

Sharp

Assuming you haven't overclocked anything and that's 3 sticks of RAM. eXtreme Power Supply Calculator says what you've got takes 253W and 6990 under load can take 375W meaning you are within margin by about 20W. That could easily change of you've overclocked your CPU, not so much if you've got 6 instead of 3 sticks of RAM.

750W of quality, and 2 nice 8 pin pcie connections as standard.

I was looking into these myself today .. for a certain other card's requirements ..

nice

I've got one 8 pin electric and I can change a 6 pin with a 8 pin with a friend so I'm alright there

And I have 3 sticks of ram.

Plus I just thought of something, if you overdo your watt to your power supply, will that increase the chance of your power supply shutting down?

If you take more watts than your power supply can handle it will shut down, there's a safety feature for that I believe. You've always got a little more than what is stated on your power supply though.
