It will fit no worries if the motherboard has a PCI 16x slot. To help you understand, the number 1, 2, 3 (in your case 3.0) stand for the version of the PCIE slot and x4, x8 and x16 is the size of the slot. If your motherboard has a 16x slot your RX570 will fit. If it has a x4 or x8 slot it will not fit.
With that specific motherboard it will fit as your motherboard has 2 3.0 16x PCIE slots.
Hope this helps.
