The standard MOQ for switching power supplies ranges from 500 units for commercial orders to 1,000 units for bulk wholesale purchases, with larger distributors requiring 20ft container quantities (approx. 10,000 units) to optimize shipping and production efficiency. Direct manufacturers often offer lower MOQs (200–500 units) for wholesale buyers, while smaller suppliers may require 100–200 units for private label or custom voltage models. Higher volumes reduce per-unit costs and cover tooling and logistics expenses, making it ideal for industrial, telecom, or data center applications.
