Power consumption Tags: New Build Power Consumption Systems Last response: January 1, 2013 5:01 PM in Systems Share CharlieBC January 1, 2013 4:32:36 PM What would be the lowest watt power supply i could have for these components, the cpu may be over clocked and it's very probable that i'll be crossfiring the GPUs.

Thanks. More about : power consumption lt_dan_zsu January 1, 2013 4:39:43 PM 600w would work, but your psu would probably burn out pretty fast. Look into a 700w maybe and get 8 gb ram. twelve25 January 1, 2013 5:01:23 PM AMD recommends 600W for Crossfire 7850, but it's better to overspec a little to leave room. I'd go 750W+ for crossfire. Keep in mind that 1GB Video RAM is going to be a major bottleneck after crossfiring. Can't find your answer ? Ask !
