So I upgraded from a radeon 6850 to a 290x BF edition this weekend.
The exact card I got is this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202058

Anyways I have a few questions. First off the recommended PSU for this card is 750w. Now I have a corsair gs700w (discontinued now). So every calculator I run says I should be using close to 600w, but I'm still worried. Should I be? Is there a way to test the watts used?
My full system specs:
i5-2500k
2x4gb ram
290x
1 x 240 gb SSD
2 x 1 tb HDD ( one at 7200, one at 10000)
2 x 5400 HDD (old laptop drives)
8 x 120mm fans + a fan controller.

My second question is regarding heat issues with the 290x. I know this card is "supposed" to run hot but it still worries me. I was ideally looking to go with an nvidia card but I bought this one for $150 of craigslist so it seemed worth it. Is there a cheap fix to the heating issues? Is something like this worth investing in? http://www.newegg.com/Product/Product.aspx?Item=N82E16835186097 I don't feel like buying after market cooling now because than I might as well have bought a 970. I may buy it in a few months, but is there an easy fix such as replacing the stock fan or removing the chasis of the card? Bear in mind I have never modded a gpu.

Thanks and sorry for the long and indirect questions, basically I'm just second guessing my purchase haha.
 


Well it runs at 95 c under load, which again is supposedly standard, but still worrisome. That's why I was hoping for a quick/cheap fix such as replacing the stock fan, but I don't know if this is possible or worth it. If not I may buy after-market cooling down the line.
 
This is my case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811139027
I have 2 intake fans in front and 4 exhaust fans( 2 at top of case, 1 by cpu, and 1 at bottom under the video card). They are all 120 mm. This case limits the cooling a tad, but again from what I've researched it's very standard for first generation 290x cards to get to 95c. I was hoping to reduce fan noise and increase card longevity. I personally doubt case cooling will improve my temps much.

Oh and my cpu temps are fine, basically in the 30-50 range depending on load.
