My power supply has been running for more than eight years, and I'm wondering whether its age or quality means it should be replaced proactively. The system uses an Intel i5-13500, Gigabyte B760M DS3H DDR4 motherboard, 32GB of Kingston HyperX memory, a Gigabyte Aero RTX 4060, two NVMe drives, one 2.5-inch SATA SSD, two 2.5-inch hard drives, and several RGB fans with a controller. The PSU is a Corsair VS450. I also use an inexpensive AVR that is more than ten years old. There are no current signs of failure, but I'd like to know whether upgrading the PSU would be sensible and what wattage or quality level to look for.

I’d replace it when practical. The VS450 is a budget-oriented model, and after eight years its internal components have had plenty of time to age. Look for a reputable modern 550W or 650W unit with a solid warranty and good independent reviews. A quality replacement should be more dependable for the next several years without needing an excessive wattage rating.
Dust it out periodically and make sure the PC has good airflow, but don’t assume every old PSU is about to fail. Some power supplies last well beyond their warranty period. I’d treat this as preventative maintenance rather than an emergency: back up important data, watch for instability, and replace the unit before a planned upgrade or if any symptoms appear.
There’s no automatic expiration date for a power supply. A well-built unit can run for ten years or more if it has been kept reasonably cool and dust-free. If the computer is stable and there are no crashes, burning smells, unusual fan noises, or power issues, replacement isn’t immediately necessary. Still, replacing it now would reduce the risk of an unexpected failure, especially since the unit is already eight years old.
The 450W capacity is actually adequate for this particular system. An RTX 4060 uses relatively little power, and the rest of the components are unlikely to bring the total anywhere near 450W during normal gaming. You don’t need a higher wattage just because of the current hardware, though a 550–650W model would give you more room for future upgrades.

That’s the important distinction here: the wattage isn’t the main concern. The age and the fact that the VS series is an entry-level line are bigger reasons to consider replacing it.
