Actually I just noticed it's for an i5 4460 which is an original Haswell. The i5 45xx and i5 46xx would be risky. You wont need to worry with that chip.
It means that the chipset of that board (the ?8??? series) was released with the first Haswell CPU's, and the new Haswell had their own chipset (the ?9??? series).
You just need to update BIOS first, which is simple. Just DL from motherboard website onto a USB and update, provided the board has a feature to let you update without CPU but that board does support new Ha\swells.
