7 years agoThe power estimator is deliberately cautious. Your design is particularly low. I'm not surprised it's a long way out.
Based on what you're measuring - no, the tool is not correct (assuming the numbers you've put in reflect your design accurately).
The spreadsheet will get considerably more accurate for higher power designs - although still conservative. It's there to ensure you design sufficient capacity into your power supplies.
