I bought a new power supply for my PC, but it's too large to fit in the case. I need it for an upgrade from an RTX 2060 to an RTX 2080, paired with an i5-10400F and 16 GB of RAM. Can I temporarily or permanently operate the computer with the PSU outside the case, and what risks should I be aware of?

Yes, it can work as long as the PSU is positioned securely, kept dry, and has plenty of airflow. The main danger is physical: someone could knock it over, tug on a cable, or loosen a connector and damage the GPU or other components. Keep it away from pets, children, and anything that could spill on it. Replacing the case or getting a compatible PSU is the safer long-term solution.
The biggest concern is accidental liquid or debris getting into the exposed PSU. Don’t place it on carpet or somewhere unstable, and make sure none of the cables are under tension. Also check the PSU’s form factor and dimensions before buying a case—standard specifications cover the basic width and height, but power supplies can vary significantly in length.
Exactly. A PSU may technically be standard ATX but still be too long for a compact case, especially when the drive bays or cable space are close to the power-supply area.
