6+2+1 Phases Hybrid Power Design

Cleaner and more efficient power delivery to the CPU with better thermal performance ensure stability under high CPU frequencies and heavy loading.

  • 6+2+1 Phases Low RDS(on) MOSFETs
  • Solid capacitors to improve transient response and minimize oscillation
  • 8-pin Solid Pin CPU Power Connector

M.2 Thermal Guard

GIGABYTE Ultra-Efficient M.2 Thermal Guard

With durability in mind, GIGABYTE provides a thermal solution for M.2 SSD devices. The M.2 Thermal Guard prevents throttling and bottlenecks from high speed M.2 SSDs as it helps to dissipate heat before it becomes an issue.

CONNECTIVITY

First adopter on 2.5 GbE LAN onboard

2X Faster than ever

Adoption of 2.5G LAN provide up to 2.5 GbE network connectivity, with at least 2 times faster transfer speeds compared to general 1 GbE networking, perfectly designed for gamers with ultimate online gaming experience.

ULTRA DURABLE

Q-Flash Plus

Update the BIOS easily without installing the CPU, memory and graphics card.

With GIGABYTE Q-Flash Plus, you don’t need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) on the USB flash drive, then press the dedicated Q-Flash Plus button and you’re good to go!
