This is a genuine Creality 350W switch power supply, designed as a direct replacement for a wide range of Creality 3D printers. It delivers stable 24V output with built-in over-voltage, over-current, and short-circuit protection. If your printer won't power on, shuts down mid-print, or shows erratic behavior, a failing power supply is often the cause. Swap it out with this official unit for a reliable fix.
