ASUS PRIME B250M-K is a Micro-ATX motherboard built around the Intel B250 chipset and the LGA 1151 socket. It’s designed to support 6th-generation (Skylake) and 7th-generation (Kaby Lake) Intel Core, Pentium and Celeron processors.
💡 Key Features
🧠 Processor Support
Uses LGA 1151 socket for Intel 6th & 7th Gen CPUs (e.g., Core i7/i5/i3, Pentium, Celeron).
Does not support newer Intel generations (8th Gen and later) because those use a different socket/chipset.
🧠 Chipset
Intel B250 chipset — a mainstream chipset offering essential features without advanced overclocking.
💾 Memory (RAM)
2 × DDR4 DIMM slots
Maximum memory: 32 GB
Supported speeds: DDR4-2400 / DDR4-2133 (Dual-Channel)
🖥️ Graphics Support
If your CPU has integrated graphics, the board offers:
1 × DVI-D port
1 × VGA (D-Sub) port
(So you can use the motherboard without a separate GPU.)
🧱 Expansion Slots
1 × PCIe 3.0 x16 slot (for a graphics card)
2 × PCIe 3.0 x1 slots (for expansion cards like sound or USB cards)
💾 Storage Options
6 × SATA III (6 Gb/s) ports for SSDs/HDDs
1 × M.2 Slot (Socket 3) — supports SATA & PCIe SSDs (NVMe).
🌐 Networking

🔊 Audio
Realtek ALC887 8-Channel HD Audio — standard onboard audio.
🔌 USB Connectivity
6 × USB 3.0 ports (some on back panel + internal headers)
6 × USB 2.0 ports (mix of back panel + headers)
🛡️ Protection & BIOS
ASUS 5X Protection III — hardware safeguards against overvoltage, ESD, and more.
UEFI BIOS with EZ Flash — easy BIOS updates and settings.
📏 Form Factor
Micro-ATX (mATX) — compact size (about 22.6 × 18.5 cm), fits in most mid-tower and compact PC cases.
📊 Pros & Cons
👍 Pros
Affordable and reliable for everyday computing builds.
Good storage options with SATA + M.2.
Standard USB connectivity and onboard LAN.
Compact micro-ATX size fits smaller cases.
👎 Cons
Only compatible with older 6th/7th Gen Intel CPUs (no newer CPUs).
Limited to 32 GB of RAM.
No built-in Wi-Fi or USB-C ports.
🧠 Good For
Basic gaming (with a separate GPU), home office, school/work builds, and everyday use.
Systems where budget and simplicity are more important than cutting-edge performance.
