Why Do Power Supply Units Fail?
When any part of your computer has trouble, it will let you know! In our last blog, we explored the signs of a power supply unit (PSU) needing to be replaced. Today, we want to dive into the world of PSUs and just what makes them fail, because the better you understand PSUs, the easier it is to keep them running.
Why Do PSUs Fail?
Electric interference damages them
- Whether it’s a power spike or lightning, when a blast of electricity hits your PSU, it may not be able to handle it and end up fried. Turn your computer off if there’s a significant thunderstorm coming your way!
They get old
- A PSU’s lifespan depends on how often you use your computer. Most warranties last from five to 10 years, but they don’t guarantee anything (except perhaps that the unit will fail after they expire).
They get clogged up and damaged
- Foreign substances like dirt, smoke, and dust damage PSUs and shorten their lifespans.
They struggle with brown-outs
- If the voltage drops but doesn’t completely cut out, a PSU has a difficult job. The main reasons brown-outs happen are for emergencies. A portable supply unit can help protect your PSU.
- Along with lightning, overheating is the most common reason for PSU failure. A computer case without proper ventilation is deadly to PSUs, so make sure you find a good case!
- Sometimes, PSUs simply stop working. You can give them the VIP treatment and they still fail. The best solution is to seek the highest quality unit you can afford.
