Sapphire 5870 Crossfire power requirements

post #1 of 6
Thread Starter 
So I have the PC Power&Cooling Silencer MK2 750W PSU and i was wondering if this is enough to power two Sapphire HD 5870 Vapor-X in crossfire? or would i need a more powerful PSU?

Thanks

You'll need at least 2 flux capacitors. 750W should be plenty.
