According to the manual, there are Marvell SE9172 SATA controllers that add an additional four SATA 6Gbps connectors to the pair that is supported by the chipset of the board. The SATA 3Gbps connectors are supported by the board's Intel Z77 chipset.
As we move to the bottom edge of the board, we see another pair of on-board buttons that power and reset the board accordingly. The button have this bronze finish and is slightly depressed in their silver plastic housing to prevent accidental presses by the unsuspecting rig builder. Located along the bottom edge of the board are the usual front panel connectors, including a 4-pin Molex power connector that will supply extra power in the event of multi-GPU setups (though most people don't use this connection).
The rear I/O ports of the board are rather run-of-the-mill; however, it does feature six USB 3.0 ports due to the presence of third-party Etron controllers. ASRock seems to have taken a leaf from the books of fellow motherboard manufacturer MSI, by including a keyboard/mouse PS/2 port just above a pair of USB 3.0 ports, as a nod to gamers who swear by the touted responsiveness of such gaming peripherals. There is a lone HDMI display port and RJ-45 LAN port. We ponder the reasons why ASRock has left out the usual suspects for video connectivity like DVI and DisplayPort, but it's quite likely they don't think they would be of use for motherboards of this class.
Besides such visible features of the board, ASRock also touts quality build of the PCB as it features a 8-layer design and comes with four sets of 2-ounce copper inner layers, that is said to ensure lower temperature and higher energy efficiency for overclocking. Hence, with that said, we shall examine the board in terms of its performance to see if it lives up to its OC accolades.
There is a velvet drawstring bag that is bundled with the motherboard and its contents had the usual offerings of SATA connector cables plus a few other surprises. One of the interesting items is a package of rubber standoffs for the motherboard that we mentioned on the earlier page. The standoffs allowed the board to be raised from any flat surface so that system builders can set up the board without the need of a dedicated test bench. There is also a syringe of GELID GC Extreme Compound that allows for easy application of the thermal paste. Another equally valuable finding is the bundled USB 3.0 front panel that supplements what your casing might have and makes reaching to the back of the system to access the rear USB 3.0 ports a last resort.
