Enough Wattage for CrossfireX?

post #1 of 4
Thread Starter 
Hey everyone!

I have a Rosewill Capstone 450W LINK HERE

I was wondering if this is strong enough to power crossfirex Radeon HD6850's. As of right now, I'm using 1 HDD, 1 SSD, Intel i5-3450, oem dvd-rw drive, 2 sticks of ram, 3 fans, and one hd 6850. I used PSUCalc and it said I'll need 500 watts, but the description on the power supply said it can do crossfirex. I want to make sure I don't have to buy a new PSU when I buy another 6850. I'm also doing some slight overclocking on my 6850, but nothing with the voltage.

Defs 600. I got 2 6850s running right now on my 620w antec high current gamer.

If you dont have them yet, getting a $300 single card would be a lot better.

Plenty, there's also no overclocking restriction.. you have a very good PSU.
