I made a thread before but i couldn't find it.

Basically i want to crossfire a HIS iceq 7950 with my current HIS iceq x2 7950. My current 7950 is clocked at 1150/1500 and my CPU is clocked at 4.5ghz.

But i am not sure if a 650watt PSU is enough, it's a corsair TX650 enthusiast model. IIRC someone said it would be fine but generally i see people speccing 750watt plus for dual card setups.

It would be handy to measure the actual amount of watts my system is using, but im guessing that would require some electrical testing equipment.

I have used a couple of online PSU calcs only to get substantially different results, so i was wondering which you would recommend and find to be the most accurate.

The other alternative is to sell my card and buy a 290/290x depending on pricing, im sure 650 will be fine for that setup.
 
Yeah i don't want to risk anything, that could be £10 towards a new PSU or 290x though :P

I might get a tester tbh so i can see what my power usage is during certain games/tasks :)
 
think ill order a tester and the card tbh, its the only way to be 100% sure im not going to overload it :)

I will run the system with each card and without to calculate how many watts each card pulls when overclocked and playing bf3/4. Then fit them both if the numbers add up in my favour.

Thanks for all the advice, if it goes **** up ill share the pictures lol
