I'm relatively new to PC setups, and I need some advice on reducing the power consumption of my desktop to make it last longer during power outages. In the winter, we experience scheduled outages where there's 4 hours of no power for every 2 hours of electricity available. I have a charging station that allows me to power my PC without electricity, but I can only get about 2 hours of use so far.
I've already tried a few things, such as enabling power-saving modes in both my BIOS and Windows, which haven't helped much, and lowering the screen brightness, which did improve things a bit. My PC specs are average, but I suspect the older PSU might be contributing to the issue. I'd like to find ways to extend the battery life without having to invest in a new charging station or switch to a laptop immediately.

The most straightforward advice is to use your PC as little as possible during outages. If you're looking to extend your time, consider switching to a laptop, which generally consumes much less power—around 20 watts compared to desktop setups that can easily range from 50 to 150 watts. Laptops can often run well under load, allowing for more battery-efficient use.

My desktop was drawing about 200W last time I checked. I think if I could trim it down to about 100W, I'd easily last the full four hours.
