Gigabyte Aorus Z270X-Gaming K5 Motherboard In Detail

Gigabyte’s Aorus Z270X-Gaming K5 is currently the lowest priced board we'll be showing you here today. Though it is available for under $160 at the moment, it features a ton of sought-after features, typically found on more expensive boards. In fact, a muted color scheme and fewer LEDs are the main differences between this board and the company’s pricier Aorus Gaming 7, which makes the K5 a tempting and more affordable option for gamers on a tight budget.
