DIY friendly

The PRIME B840-PLUS WIFI motherboard features EZ PC DIY innovations that simplify and speed up the PC building process, making DIY easy and convenient.

• Q-Antenna- With Q-Antenna, attaching a WiFi antenna to your PC is now easy and fast. Instead of slowly rotating two fasteners until they finally lock in, they just snap into place. Less hassle, and more consistent performance.
• Q-LED Core- The Q-LED Core display produces color-coded lights during the Power-On Self-Test (POST) that can help you troubleshoot potential issues.
• Pre-Mounted I/O Shield- Our pre-installed I/O shield safeguards ports, simplifies the build process, increases functionality, and enhances aesthetics for PC DIY enthusiasts.
• BIOS FlashBack- BIOS FlashBack simplifies BIOS updates. Just load the BIOS file onto a FAT32 USB stick, insert it into the BIOS FlashBack port, and press a button – no CPU or memory needed.
• SafeSlot Core+- SafeSlot Core+ is a one-piece stainless-steel brace that shields the slot to protect it from damage. The metal cover is tightly secured to the slot with hooks, and the entire assembly is firmly anchored to the PCB with strengthened solder points to provide a secure foundation for heavyweight graphics cards.
