Overview

Standard motherboards are the most common type of circuit board found inside desktop computers. They serve as the central platform that connects the CPU, RAM, storage, and expansion cards - effectively the backbone of the entire system.

 

Most are ATX or micro-ATX in layout, with a familiar mix of CPU sockets, RAM slots, PCIe connectors, and rear I/O ports.

​

In recycling, these boards form the baseline category. They offer moderate yields of precious metals, especially when fully populated with chips and connectors. But, they generally lack the high-density gold and specialised components found in server or telecom boards.

Identifying a Standard Motherboard

​​

Typical features include:

• A large CPU socket with metal bracket or pins

• 2–4 RAM slots, long and parallel

• Several PCIe slots for graphics or expansion cards

• I/O ports such as USB, HDMI, or Ethernet along one edge

• Flat, low-profile capacitors and visible copper traces

 

The reverse side is usually smooth, showing solder points but few mounted components. Boards from gaming or high-performance systems may include decorative heatsinks or RGB fittings, but these do not usually add scrap value.

Preparation for Recycling

​

Before selling or recycling:

​

1. Remove the CPU and its heatsink - the CPU has separate value, and the heatsink adds non-recyclable weight.

2. Other heatsinks can remain, as they are typically attached to voltage regulators or chipsets and are accounted for in standard grading.

3. Remove the coin-cell battery from the motherboard - these cannot be accepted due to hazardous material regulations.

4. Detach metal backplates if easily removable.

 

A complete board with intact ICs and connectors will always achieve a better grade.
