1. Power supply requirements for desktop PCs
Note that the following only applies to desktop PCs.
Power supplies for laptop PCs are always designed with the correct Wattage.
The power supply is a very important component. An inferior quality power supply or too low Wattage may cause your desktop PC to reboot if it cannot cope with sudden spikes in demand while you're using Lumion and other demanding 3D applications.
For that reason, we strongly recommend using a power supply from a reputable manufacturer such as Corsair, Super Flower, EVGA or Seasonic.
The power supply should ideally be marked as Gold-rated 80+, Platinum-rated 80+ or Titanium-rated 80+, which means that it is very efficient and can maintain a steady current in spite of fluctuating demand.
2. Which power supply do you need for common desktop PC graphics cards?
Here's an overview of the power supplies you need for various NVIDIA graphics cards:
- NVIDIA RTX 3090: Minimum 800W. We recommend at least 950W.
- NVIDIA RTX 3080: Minimum 700W. We recommend at least 850W.

3. How many Watts does your power supply need?
This will depend on the graphics card and how many components, hard-drives and other components your desktop PC has.

3.2: Please click here to look up the minimum required Wattage if you have an AMD graphics card:
- External Link: AMD graphics cards
We recommend adding about 150 Watt to the NVIDIA or AMD recommendation to be on the safe side.
IMPORTANT NOTE FOR DELL & HP OWNERS: Some power supplies in Dell and HP computers with high-end graphics cards are known to make the computer restart when you start rendering Photos or Movies in Lumion. A number of users reported that the reboots stopped occurring after they replaced the Dell/HP power supplies with power supplies from reputable manufacturers (80+ gold-rated or better and with a sufficient Wattage).
Unless you can replace the power supply with a more suitable one, you will need to limit the amount of power to the graphics card via an app called MSI Afterburner, so that the graphics card runs slower. This will prevent the PC from restarting in most cases:
