Just as the title says, the ASUS Matrix R9280X requires a 8+8 pin pcie power requirement, does the z87 ud4h only have 1 8pin? if so am i better getting the ASUS R9280X DC2 where it needs 6+8 or better getting a new Mobo with 8+8?? If you could explain what the pins and technical stuff is as well would be appreciated, having difficulty researching the two products.
