As stated several times through this thread, if you're doing a gaming build you should stay with LGA1155 and Z77 chipset (with either an i5 3570K or i7 3770k). Going LGA1156 or 2011 will only make you spend a crapload of extra money for almost neglige benefits. Same goes for RAM speeds, unless you're going to use the PC for hardcore benchmarking anything above 1600 is diminishing returns. Put that extra money in something like a 680 instead.
For the black-red-white theme, get an Asrock Fatal1ty or Asus Maximus mobo.
And about the Power Supply, I'm more than sure it can be scaled down a bit unless you plan on adding a second GPU later down the line.
Anyway, you have the final word but at the very least, I'll say that the mobo you chose is extremely overkill and overdimensioned unless you're going to install those 4 GPUs it allows.
Edit: sorry, but I'm still wating for feedback about this particular PSU:
