FAQ - Frequently Asked Questions
Answers
1. I can calculate the recommended Power Supply wattage in Lite version. Why would I switch to eXtreme Power Supply Calculator Pro?
The eXtreme Power Supply Calculator Lite provides you with recommended total Power Supply Wattage only, which gives you a general idea on what to look for in Power Supply. However, wattage is NOT crucial factor in Power Supply selection!
Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage.
Example: Power Supply that you would like to buy has 400W total wattage output but only has 16A on +12V rail. Depends on the Video Card and CPU selected you might easily rich 18-28A on +12V! Consequences? Best case scenario:
your PSU has overload protection and it will shutdown the system. Worst case scenario: you might 'fry' some of your components, like motherboard, video card, hard drive, etc.
2. Are all computer components available in Lite version also available in Pro version?
Yes. Pro and Lite versions contain the same components.
