Does MSI Z87 MPOWER 1150 take 7x7970 ?

[mrkengz]

Hi, i'm new here. I did some reading for a while and decided to build a 4x7970 system. I found this mobo, MSI Z87 MPOWER 1150, have 4 pcie-x1 and 3 pcie-x16, which typically takes 7 GPUs (w/ risers).

so, I just want to make sure that it will do before buying.
Thank you.
