i have 2 xfx hd7770
970 pro3 r2
phenom II X4 965 3.4GHZ
8 GIG 1600 corsair
now with a very cheap ace 750 w psu
with the following connections
3 x sata
motherboard is a 8 pin i have 4 to 8 pin power
one card has a 6pin
im using the molex line to run 2-4 120mm fanns and a molex to 6 pin pcie
the mobo crossfire runs 1x 16@2.0
second one 1x4@2.0
........
i looking to change a couple of bits
PSU = OCZ ZS Series 750W 80+ Bronze PSU with 135mm Fan & single +12V Rail
MOBO = AsRock 990FX Extreme3 Motherboard
