What power ratings of power supplies are used for LED displays, and what are the common brands?

The most widely used power supplies for LED displays come in three main power ratings: 200W, 300W and 400W. The popular mainstream brands include Chuanglian, Rongdian and G-energy. These brands enjoy large market circulation. Many lesser-known brands also deliver reliable quality, yet they have not achieved large-scale production and cannot offer prices as competitive as these major manufacturers.

Both LED display power supply manufacturers and LED display brands grow step by step, expanding scale first and then enhancing overall strength. The LED display industry has a history of over 30 years, and its related technologies and products are now fully mature. With 16 years of experience in this field, I am quite familiar with the industry practices. Many listed brands accept orders at high prices, and then outsource production and installation to smaller companies.
