Which power supply do you need?

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 or transient spikes in demand while you are 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.

 Your chosen unit should carry an official certification rating of 80 PLUS Gold, 80 PLUS Platinum, or 80 PLUS Titanium. These designations guarantee high-efficiency electrical conversion thresholds, maintaining clean continuous power delivery despite rapid system demand fluctuations 

 For current-generation components, ensuring your hardware is certified for the ATX 3.1 specification standard is strictly required to securely regulate power excursions and transient surges. 

Here's an overview of the power supplies you need for various graphics cards:

For models not listed here, please see the section below: 3. How many Watts does your power supply need?

Examples of some high-quality power supplies:

• Seasonic Prime TX-1600 Noctua Edition
• EVGA SuperNOVA 1600 P2 1600 W "80 Plus Platinum"
• Corsair HX1500i ATX 3.1
• SeaSonic PRIME PX-1300 1300 W "80 Plus Platinum"
• Seasonic Vertex PX-1200 ATX 3.1
• EVGA SuperNOVA 1000 G+ 1000 W "80 Plus Gold"
• Bitfenix Whisper M Series 850W 
• 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"
• Corsair AX850 850W "80 Plus Titanium"
• Seasonic Prime 600W Titanium Fanless

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:

We recommend adding at least 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:
