How to Run Minecraft on 64 Batteries: A Crazy Desktop PC Experiment

Imagine this: the power is out, but your desire to build a new house in Minecraft outweighs the circumstances. An enthusiast and creator of the YouTube channel ScuffedBits took a bold step and assembled a fully functional desktop PC powered solely by 64 standard AA batteries. And yes, you can actually play on it.

Why build a battery-powered PC?

Sometimes, we just need a good technical challenge. For ScuffedBits, this project became a major learning experience. In his first attempt, he managed to keep the PC running for only about five minutes, barely enough to load the operating system, let alone launch games. So, he decided to completely rethink his approach to maximize the potential of standard batteries and prove that autonomous gaming is possible even under such unusual conditions.

Technical Magic: What's Inside and How It Works

The experiment was based on a modest but functional setup: an Intel Core i3-530 processor, 8 GB of RAM, and a WD SATA SSD. The main issue with the previous failure was the power supply design — thin wires caused excessive resistance.

To ensure stable operation, the creator made several critical changes:

• Modified the battery block configuration, raising the starting voltage to about 25 V.
• Installed three parallel voltage regulators, which provided a steady 12 V required to power the PC components.
• Abandoned unreliable crocodile clips and soldered all wires directly to the contacts.

Thanks to these modifications, the PC was able to start and load Windows without any additional power from the outlet.

From Synthetic Tests to Block Mining

The new power setup delivered impressive results. The system ran for 33 minutes and 19 seconds, increasing the autonomous runtime sixfold compared to the first attempt.

During this half-hour, ScuffedBits achieved a lot. First, he successfully ran the demanding Cinebench CPU test to check the system's stability under load. After confirming the PC's resilience, he installed and launched Minecraft. After playing in the blocky world, he attempted to download Portal 2, but at that moment, the batteries finally ran out.

Later, the creator tested the same setup with a standard 12-volt car battery. The PC could have easily run for 3–4 hours on it, but the author rightly noted that such a solution lacks the spirit of adventure and fun.

What Do You Think?

The experiment proved that with a proper approach to electronics, even a handful of simple batteries can power desktop hardware. How do you evaluate this approach to autonomous gaming? If you had exactly half an hour of PC runtime on batteries, which game would you launch first? Share your choice and thoughts in the comments!
