The Gigabyte GA-Z87X-OC is a special mainboard optimized for overclockers. It is designed to be used as an open testbed for overclocking experiments and some of its features have already been implemented in other products. For example, it has switches that let you change the configuration of your PCI Express x16 slots without physically removing your graphics cards. It offers connectors and check points for measuring voltages manually with a voltmeter. It also has some unique features like the OC Brace for fastening expansion cards and the OC Ignition button for shutting the computer down while keeping the fans and drives powered up. It uses an unconventional speed formula for the PCI Express x16 slots, allowing you to install up to four graphics cards without using additional PCIe switches.
This mainboard has few additional controllers, actually. And even though the Intel Z87 chipset is very functional, the GA-Z87X-OC may not be quite appropriate for a home PC. Its numerous onboard buttons, switches and connectors won’t be accessible in a closed computer case. Moreover, like some other mainstream and top-end Gigabyte mainboards, it is not economical and has some problems with power-saving technologies.
Thus, the GA-Z87X-OC is best used for its intended purpose, i.e. for overclocking on an open testbed. For a home PC, you may want to prefer some other models, perhaps even from some other brand, considering that Gigabyte’s LGA1150 products are somewhat inferior in terms of power consumption.
