This invention relates to the field of computer manufacturing technology, and in particular to a computer host power supply with a negative ion generator. The power supply includes a casing and an air inlet and an air outlet. A detachable dustproof frame is located at the air inlet on the casing. By having high-voltage electrode plates slide along with a scraper, the release point of negative ions changes from static to dynamic coverage, achieving wider air purification. Furthermore, while enhancing the ionization effect, it also breaks down the electrostatic saturation layer of dust on the surface of the collection plate, allowing the electrostatic adsorption capacity to be maintained for a long time, significantly improving the continuous collection efficiency of dust and particles. The auxiliary scraping mechanism works in conjunction with the scraper to automatically remove adsorbed dust and impurities. The dustproof frame is detachable, allowing for easy removal when deep cleaning or maintenance is required, thus achieving efficient, long-lasting, and maintenance-free active purification and dust removal of the air inside the computer case.
