Recently, a client came to our computer workshop in Tallinn, ARVUTIABI-ESOFT OĆ, with a PC that wouldnāt turn on. He explained that he had assembled the computer himself, carefully selecting components from different stores to reduce costs. It was his first experience building a PC, and while he approached the task responsibly, he made a critical mistake that damaged one of the systemās key components.
šØ The Clientās Story: A Mistake That Cost Him a Motherboard
The client purchased new components for his build, including a case, motherboard, processor, 64GB of RAM, and a liquid cooling system. Everything indicated that this would be a powerful and reliable machine. However, to save money, he decided to reuse the power supply unit (PSU) from his old computer, as it was relatively new, modular, and powerful enough for the build.
The problem began when the client realized he had lost some of the cables (āharnessesā) for his modular PSU that he hadnāt needed in his previous build. The new motherboard required two 8-pin connectors to power the processor, but he didnāt have an original additional cable. Instead, he found a solution: he borrowed a cable from a modular PSU of a different brand, connected it to his PSU, and plugged it into the motherboard.
The result? The computer wouldnāt power on. After several failed diagnostic attempts, the client brought the PC to our workshop. Upon inspection, we found that the motherboard had been damaged due to incorrect voltage from the incompatible cable.
ā” Why You Should Never Use Cables from Other Modular PSUs
Modular power supplies from different brands use unique wire layouts. Even if the cables look identical, their internal wiring can differ significantly. Using a cable from another PSU can cause short circuits, damage components, or completely destroy them.
Important to Remember:
- A cable from another PSU may physically fit, but that doesnāt guarantee compatibility.
- Always use original cables provided by the manufacturer.
š ļø Personal Experience: Store Your PSU Cables Properly
From personal experience, I can emphasize the importance of keeping PSU cables. When my modular PSU from MSI failed, the service center required the full PSU set, including all original cables. Luckily, I had kept everything intact, which allowed me to get a replacement PSU under warranty.
Tip: Manufacturers like MSI often include convenient pouches for storing PSU cables. Use them to avoid losing essential components.
ā How to Avoid Such Mistakes?
- Use Original Cables: Never connect cables from other modular PSUs.
- Store All Components: Keep all cables and accessories together with the PSU. This is essential for compatibility and warranty claims.
- Consult Professionals: If youāre unsure about compatibility or fear damaging components, trust professionals to assemble your PC.
