I use a high-end workstation with a 285K processor, RTX 5080, 64 GB of DDR5 memory, and a 5 TB SSD. It draws around 100 watts even while idle, and electricity is expensive, so I shut it down whenever I'm not using it. Some days I turn it on and off two or three times. Could these frequent power cycles or the temperature changes damage the components, or is it better to leave the computer running?

Turning it on and off a few times per day is perfectly normal and shouldn’t harm the PC. The small amount of thermal cycling is generally insignificant compared with the electricity saved by shutting down a system that consumes about 100 watts at idle.
There’s no need to keep it running just to avoid power cycles. Since your storage is an SSD, you also don’t have to worry about a mechanical hard drive repeatedly spinning up and down. Leaving the machine off when you aren’t using it can reduce operating hours and may even protect it from some power disturbances, especially if you don’t have a UPS.
Two or three power cycles a day is a very light workload for modern components. A normal shutdown is safe; just avoid cutting power with the switch or unplugging the system while it is running. If you want faster startup, sleep or hibernate are alternatives, but they are not required.
The only practical reason to leave it on is convenience, such as needing remote access or wanting background tasks to continue. Otherwise, shutting it down when you’re finished is a sensible way to save power. Restarting occasionally is also useful for applying updates and clearing up software problems.
That makes sense. I was mainly worried that the repeated temperature changes would be worse than the constant heat from leaving it on.
