SKU CH-XEP5-690JT

  • LGA 1155 socket fits compatible Intel CPUs

  • HDMI output drives displays without extra cards
  • SATA 6Gb/s ports deliver fast storage speeds
  • USB 3.0 ports provide quick data transfers

TZ75B LGA 1155 motherboard

The Biostar TZ75B is an ATX motherboard built for the LGA 1155 platform. It targets system builders who need a tested replacement board or a base for a legacy Intel build. The board arrives without original packaging and includes only the I/O shield. A 60-day warranty covers the unit.

Connectivity and daily handling

The rear panel provides HDMI video output alongside SATA 6Gb/s ports and USB 3.0 headers for fast storage and peripherals. UEFI BIOS replaces the older legacy interface for cleaner configuration. Pins in the CPU socket are delicate; the supplier warns that bent pins void coverage, so the protective cover must be opened with care.

Upgrade context and fit

This board suits owners of an existing LGA 1155 system who need a working Z75 foundation without buying a full platform change. It does not serve builders who require newer socket types, modern storage protocols or current-generation memory support. The jump makes sense only when the rest of the components already match the 1155 ecosystem.

Questions about this item

What does the SATA 6Gb/s interface cap in practice?

The SATA 6Gb/s interface caps the maximum theoretical throughput of connected drives at six gigabits per second.

What physical items are included so the board can mount in an ATX case?

Only the motherboard and the I/O shield are included; no original packaging or extra brackets are supplied.

How is the CPU installed in the LGA 1155 socket, and what step do people often get wrong?

Lift the socket cover carefully, align the processor notches, lower the CPU without forcing it, then close the lever; the step people miss is opening the cover gently to avoid bending the socket pins.
