Socket LGA 1151 ATX Motherboard

The GIGABYTE B250-HD3P is an ATX form factor motherboard built around the Intel B250 chipset and the LGA 1151 socket. It accepts 6th and 7th generation Intel Core i7, i5, i3, Pentium and Celeron processors. Four DDR4 DIMM slots support up to 64GB of system memory for mainstream desktop builds.

Sustained Load Behaviour

The board delivers a single PCI Express x16 slot wired for x16 operation, keeping a discrete graphics card at full bandwidth during extended rendering or compute sessions. Six SATA III ports, one SATA Express connector and one M.2 interface provide multiple storage pathways that maintain throughput without thermal throttling under continuous read and write cycles.

Interface Practical Limits

Onboard connectivity centres on USB 3.1 Gen 2, with one rear Type-C port and one red Type-A port each capped at 10 Gbit/s. Additional USB 3.1 Gen 1 ports from the chipset run at 5 Gbit/s. The Intel Gigabit Ethernet controller tops out at 1000 Mbit/s, while the Realtek ALC892 codec handles up to 7.1 channel high definition audio output.

Highlights

  • Supports 7th and 6th gen Intel CPUs with LGA 1151 socket

2 PCI Express x16 slots with x4 operating specifications (PCIEX4_1/PCIEX4_2)
* Since SATA Express, PCIEX1_2 slots share bandwidth with PCIEX4_1 slots, PCIEX4_1 slots * operate at x2 bandwidth when SATA Express interfaces have expansion cards installed, and PCIEX4_1 slots * operate at x1 bandwidth when PCIEX1_2 slots have expansion cards installed.

Questions about this item

How much power does the B250-HD3P draw and how hot does it run under all-day load?

The board uses the Intel B250 chipset and LGA 1151 socket; actual power draw and temperature depend on the installed CPU and cooler, not the motherboard alone.

Which DDR4 memory and LGA 1151 processor must I already own for this motherboard to work?

You need a 6th or 7th generation Intel Core i7, i5, i3, Pentium or Celeron for the LGA 1151 socket, plus up to 64 GB of DDR4 across the four DIMM slots.

Will my existing SATA drives and PCIe add-in cards work alongside the B250-HD3P?

Yes — the board provides six SATA III ports, one SATA Express interface and one PCI Express x16 slot plus two PCI Express x1 slots for older expansion cards.
