Updated: 04/26/2017 by Computer Hope

For users planning on building a computer, a motherboard can be a confusing and sometimes frustrating decision. Below we have listed some considerations and tips when looking at purchasing a computer motherboard.

Type

The type, or form factor, of the motherboard is a crucial consideration when looking at a motherboard. There are various form factors and not all computer cases can accommodate each form factor. Today, the most commonly found and used motherboard is the ATX motherboard. When looking at the motherboard, make sure your case supports your motherboard form factor. Additional information and help with the form factors can be found on our motherboard page.

When looking at who to purchase a motherboard through, consider all brands motherboards since all motherboards have positive and negative reviews. A listing of motherboard links and manufacturers can be found on the motherboard section of our network.

Considerations

CPU socket or slot

There are a wide variety of different CPU sockets and slots. When looking at purchasing a motherboard, ensure it is compatible with the CPU you have or that it will be compatible with the CPU you plan on purchasing.

Additional information about CPUs and the sockets or slots can be found on our CPU buying tips page.

Drive connectors

Drive connectors can be an important consideration when purchasing a computer. Determine the interface of the drives you plan on using, and ensure that the motherboard supports that interface or has the connector for that interface. An example of such an interface is IDE, EIDE or SCSI.

Slots

The available slots can be an important consideration. Below is a listing of the different slots used in motherboards.

  1. PCI Express - The latest and greatest slot and bus type.
  2. AGP - AGP, or Advanced Graphics Port, is used for video cards as a replacement for PCI.
  3. AMR - AMR, or Audio Modem Riser, is a slot that is used for audio and modem cards and is found on some motherboards. This is not a critical slot and has been replaced by the CNR.
  4. CNR - CNR, or Communication and Network Riser, is a slot that supports audio, modem, USB, and Local Area Network cards. This slot is highly recommended for any user building a large amount of computers as the cards are cheaper than the standard PCI or ISA cards.
  5. ISA - Today, ISA is becoming obsolete and is not found on all motherboards. Unless you have old ISA cards that need to be used, it is recommended you purchase a new motherboard with no ISA slots and additional PCI slots.
  6. PCI - The most widely and commonly used slot.

Jumpers

Jumpers are overlooked when considering a motherboard; however, they can be an important consideration, especially for users who plan on overclocking their computer. Below is a listing of some of the jumpers that should be asked about or known when purchasing a computer motherboard.

  1. Does the motherboard have a clear CMOS jumper?
  2. Does the motherboard have CPU settings jumpers? Or is it configured through CMOS? Is it auto detect?
  3. Does the motherboard have onboard video or sound? If yes, can they be disabled with jumper or is it done through CMOS? Note: either way is fine as long as it can be disabled.

USB ports

While all motherboards today have USB ports, ensure that the motherboard you plan on purchasing has USB ports.
