QUESTION
Which power supply do you need?

ANSWER
An inferior quality power supply may cause your PC to spontaneously reboot if it cannot cope with sudden spikes in demand while you're using Lumion (and other demanding 3D applications).

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- or Titanium-rated 80+ which means that it is very efficient and can maintain a steady current in spite of fluctuating demand.

Here's an overview of the power supplies you need for high-end Nvidia GTX graphics cards:

Nvidia GTX 1060: Minimum 400W gold-rated power supply but we recommend at least 550W.
Nvidia GTX 1070: Minimum 500W gold-rated power supply but we recommend at least 650W.
Nvidia GTX 1070 Ti: Minimum 500W gold-rated power supply but we recommend at least 650W.
Nvidia GTX 1080: Minimum 500W gold-rated power supply but we recommend at least 650W.
Nvidia GTX 1080 Ti: Minimum 600W gold-rated power supply but we recommend at least 750W.

Examples of good power supplies:
  • Seasonic Prime 600W Titanium Fanless
  • Bitfenix Whisper M Series 750W "80 Plus Gold"
  • XFX XTR Series 750W "80 Plus Gold"
  • Super Flower Leadex GOLD 750W "80 Plus Gold"
  • EVGA SuperNova G3 750W "80 Plus Gold"
  • Corsair RM Series RM750X 750W "80 Plus Gold"
  • Corsair RM1000i 1000W "80 Plus Gold"
  • Super Flower Leadex Platinum 750W "80 Plus Platinum"
  • EVGA Supernova P2 750W "80 Plus Platinum"


Regarding the Wattage of the power supply, this will depend on the graphics card and how many components, harddrives etc your PC has.

Please click here to look up the minimum required Wattage if you have an Nvidia graphics card.
Please click here to look up the minimum required Wattage if you have an AMD graphics card.

We recommend adding about 150 Watt to the Nvidia/AMD recommendation to be on the safe side.

NOTE FOR DELL & HP OWNERS: Some power supplies in Dell and HP computers are known to cause instant reboots when you start rendering images/movies in Lumion. A number of those users reported that the reboots stopped occurring after they replaced the Dell/HP power supplies with power supplies from reputable manufacturers (80+ gold-rated).

The power supplies of certain Dell workstations will only work with the graphics card that they are delivered with (or low to medium-end graphics cards). Unless you can replace the Dell power supply with a more suitable one, you will often not be able to use high-end graphics cards like the GTX 1070, 1070 Ti, 1080, 1080 Ti and Titan Xp.
