Target platform

The Fatal1ty B85 Killer is an LGA 1150 ATX board built around the Intel B85 chipset for fourth generation Core i7, i5, i3, Xeon, Pentium and Celeron processors. It targets gaming and enthusiast builds that need legacy DDR3 memory support and classic expansion slots.

Thermal and power profile

The B85 chipset runs cool enough for standard air cooling with no active heatsink required. Turbo Boost 2.0 on supported CPUs raises clock speeds within the stock power envelope, so a typical case airflow setup keeps thermals and noise in check without extra measures.

Bundled networking advantage

The onboard Qualcomm Atheros Killer E2200 controller prioritises gaming traffic and reduces latency during heavy network loads. Realtek ALC1150 audio delivers 7.1 channel output with dedicated headphone amplification, improving positional sound in games and media playback.

Questions about this item

Will this board take a 4th-generation Core i5 and 32 GB of DDR3-1600?

Yes, the LGA 1150 socket supports 4th-generation Core i7, i5, i3, Xeon, Pentium and Celeron CPUs, and the four 240-pin slots accept up to 32 GB of DDR3 at 1600, 1333 or 1066 MT/s in dual-channel mode.

How many SATA 6 Gb/s drives can I connect without an extra controller?

Four SATA 6 Gb/s ports are provided on the board, so you can attach up to four drives directly.

Does the Killer E2200 LAN need a separate driver, or does Windows 10 include it?

Windows 10 includes a driver for the Qualcomm Atheros Killer E2200, but the vendor-supplied driver adds the traffic-prioritisation software that the chipset is designed for.
