Is my PSU large enough! Please help. Ordering soon and I need to know.

Solution
You linked to the 850W, but you said 650W. Which is it?

The 650W is plenty for what you have. The 850W is plenty to add another 7970 for crossfire later



my bad, i mean to link to the 650 one 🙂 thanks
 


my friend just now recommended that i change to this build? what do you think? link to a screenshot.

That is also a solid build but I would replace the motherboard with a 990FX Extreme3.

what would the difference be?
