Which power supply should I choose?

Power supply can't just look at the rated power, and some brands will falsely mark the power. Therefore, the first choice of power supply is brand. At present, most of the first-line brands are Taiwan Province brands, such as Haiyun, Delta, Quanhan, Zhenhua Kingdee and Kang Shu. You can also use some models of power supply, such as Annaimei, Antaike and Pirate Ship. According to your configuration, you only need to buy a standard rated 450W, which can also be used when upgrading your computer in the future. You can buy Delta nx450 or Amei nx450.
