3x7950s from tx850W PSU with 4*8 pin power cables

al3xms · Dec 2, 2013

Looking to see if i can use 3 7950s in my PC

Would the best way to power the third card be to use a 8pin to 2*6pin slitter..if they exist
or use 2 molex to 6Pin cables?

the 12V single rail has a max load of 70A
the PSU is 80 Plus

Use a molex to 6pin. It's easier and usually comes with the cards in the box.

thanks for your reply, is it safe to use them like this
card 1, 2x6 pin pci
card 2, 1x6 pin and 1x molex to 6pin
card 3, 1x6 pin and 1xmolex to 6pin

You can do it that way, but why not use the 2x6pin pci connector for 2 cards and 1 molex for the other? DOesn't really matter honestly either way though.
