Discussion Overview

The discussion revolves around the necessity of a 12V 4-pin square power cord for a computer upgrade involving a specific motherboard and CPU. Participants explore the implications of power supply requirements and compatibility issues related to hardware upgrades.

Discussion Character

  • Technical explanation, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions the necessity of the 4-pin power cord as indicated in the motherboard installation manual, expressing uncertainty about whether it is essential for booting the system.
  • Another participant asserts that if the installation manual specifies the need for the 4-pin connector, it is likely required.
  • A different participant emphasizes that power supply specifications have changed over the years, suggesting that an upgrade to the power supply may be necessary to meet the demands of the new motherboard.
  • Several participants agree that upgrading the power supply is advisable when upgrading the motherboard and CPU, particularly if the existing power supply lacks the required 4-pin connection.
  • One participant raises the possibility that the current power supply may not provide sufficient wattage for the new components, indicating a potential need for a new power supply.

Areas of Agreement / Disagreement

Participants generally agree that a 4-pin power connection is likely necessary for the CPU, but there is no consensus on whether the existing power supply can adequately support the new components without an upgrade.

Contextual Notes

The discussion does not resolve the specific requirements for the power supply or the implications of wattage needs, leaving these aspects open to interpretation based on individual hardware configurations.

Who May Find This Useful

Individuals upgrading their computer hardware, particularly those dealing with power supply compatibility issues related to motherboards and CPUs.

Hi There Please Anybody Than Can Help
I Am Upgrading Computer Running Into Problem
Mobo Msik9n Sli V2
Cpu Amd Athlon 64x2 4600

If the installation manual says you need it you probably need it.

An extra 4 pin molex is sometimes needed to give power to the CPU or graphics card. If you're using a standard ATX power supply there should be a few extra connectors there.

Yes, you really do.
They changed the power supply specifications several years ago.
You need to upgrade to power supply to match the new mobo.
 
Always upgrade your PSU if you upgrade the motherboard and CPU, especially if the existing one doesn't have a 4pin connection.
 
You might also need a new PSU because it can't give your components the wattage they need in the first place.
