Post by: ptshamrock on June 01, 2011, 11:25:37 AM
..without using extra adapters? wich PSU is good for that?

how much is the maximum watt? 4x375 on full power right?

mainboard is MSI 890FXA-GD70     (Socket AM3

AMD Sempron 145 2.8GHz Box

POWERCOLOR Rad. HD 6990 4096MB Rt.  

 CORSAIR CMPSU-1200AXEU 1200W was planned but is that enuff??


and of course i want do downclock the memclock ..what would be a good value??

how much can i reduce the watt per card and still run them at around 800mh/s?

The heat will be too much of a problem unless you water cool.  They will not last.

where they say i have 30% less heat ..is ith workbale then?

i have added all possible coolers and maybe will only work 3 of them at every machine..

but for now i need to know if it works out with the power consumption on the 1200watt PSU ?

thank u very much for ur help!

Do note, You will still need a radiator/pump and reservoir for those water cooled cards. All they come with is a waterblock preinstalled.
