Gigabyte Z97X-Gaming G1 WIFI-BK Board Review

With every new chipset launch we see couple of motherboards standing apart from rest of the crowd; in terms of features, innovation, and performance. Gigabyte's Ultra durable Z97x-GAMING G1-WIFI Black Edition board is one of such board. Based on the Intel Z97 Express chipset , with more conservative heatsinks with Custom Water-Cooling support, better multi-GPU capabilities, and true overclocking features, one can safely assume that the Gaming G1 WIFI-BK resembles an OC board just as much as a pure gaming board.

Package - Inside the box

Looking at the front of the box, we see gigabyte logo with Ultra durable and Black Edition graphics and motherboard model no. At the rear of the box, we find that Gigabyte goes into great detail on the specifications of the motherboard. Opening the box gives a glimpse of the actual product.

Moving into the bundle, we've actually got a fair bit included. Since the Gigabyte Z97x-GAMING G1-WIFI is capable of 4 way SLI, Gigabyte has provided nearly all the options available for SLI but only 1 Crossfire bridge alongside a front 3.5 bay USB 3.0 Connector, PCI-e Wi-Fi 802.11 a/b/g/n/ac, supporting 2.4/5 GHz Dual-Band card with antennas , rear I/O, SATA cables, drive disk, manual and last a Certificate of Unmatched Stability and Reliability indicating that the board has passed an extra 168 hours of stress testing. Cool.


Board is a solid build in a black and red colour theme.
