For your convenience we summed up all the Intel DZ77BH-55K technical specification sin the following table:
As you can clearly see, Intel DZ77BH-55K mainboard from the “Media” series is not as primitive as we assumed it would be. The generally good features set offered by the Intel Z77 Express chipset has been successfully expanded with a number of additional controllers and interfaces. The board supports IEEE1394 (FireWire), has two additional SATA 6 Gbps ports and an eSATA 3 Gbps port on the back panel. Another onboard USB 3.0 pin-connector, which could have been placed at a little more convenient spot, allows adding two more USB 3.0 ports to the front or the back panel of your system case. Although there is some free space on the back panel, they managed to load it with various important connectors and ports, despite the fact that there are a lot of video outs of all kinds there, too. We have already mentioned a number of nice bonus functions that make working with this mainboard much easier, such as Power On and Back to BIOS buttons, POST-code indicator, VR Status LEDs and Board Status LEDs. So, after all, Intel DZ77BH-55K mainboard is a pretty contemporary fully-functional mainboard with right set of features.
