Introduction

Investing in quality PC parts means expecting longevity, but no component lasts forever. Understanding the average lifespan helps plan upgrades proactively.

CPUs and RAM

CPUs and RAM modules are generally the most durable components, often lasting 10 to 15 years under normal thermal conditions. They are more likely to become obsolete before they fail.

Graphics Cards (GPUs)

GPUs have a shorter practical lifespan, typically 5 to 7 years. Heat is the primary killer here. Look out for artifacting or fan failures as early warning signs.

Power Supply Units (PSUs)

PSUs are the silent heroes, but they degrade fastest due to constant electrical stress. High-quality units should last 7-10 years, but failure can be catastrophic. If your PSU is over 8 years old, consider proactive replacement.

Storage Drives (SSD/HDD)

SSDs are rated by Terabytes Written (TBW). Most modern SSDs far exceed the needs of average users. HDDs, however, are mechanical and have a higher risk of sudden failure, usually after 5 years of heavy use. Back up critical data religiously.

Conclusion

Component longevity is heavily dependent on cooling and power quality. Good thermal management is the best insurance policy for your investment.
