I have the THERMALTAKE 470 WATT
and the THERMALTAKE 650 WATT with cable management
Now i would like to make a crossfire between two HD5770, i have 4 hard drives, i7 930, ASUS rampage extreme, 6 Gb DDR3 - 1600.
the case will be Coolermaster 690 advanced with all 10 fans.
All the calculation i made shows that i need at least 789 Watts.
Can i use the 2 PSUs that i have or should i spend more money for a new psu??
if you can fit both PSU's then you can, the trick is getting a way to tell the second PSU to power up, the one way I know of how to do that is by shorting one of the green colored pins on the 20/24 pin connector to any of the green ones... as long as that 'short' is connected, the PSU will be powered up.
I have a first gen coolermaster stacker, and that one had a special jumper cable that attached to both PSU's and the motherboard, maybe someone can find the schematics of it and you can make one similar to it?
all in all, if you can get just one PSU to power everything, it would be allot easier on you. (less cool, IMO, however.)
oh, and that seems like -allot- of wattage for that system... where did you get the numbers for that?
if your case fits two PSUs then all you have to do is get this adapter and your good to go.
this adapter plugs into the motherboard and both PSUs plug into it, the motherboard takes the power from one PSU but controls both PSUs
but it would be easier just to run one big psu than two
I dont know I just get in to one of the calculators at google and it showed me 739 WATTS - Is it possible ???
its possible but slightly unreasonable, what are your complete specs?
