Is it necessary to choose a gold power supply?
80plus, bronze, silver, gold In fact, 80plus is only a certification standard for power conversion efficiency.

1, low-end office home: the use of I3-class CPU, the use of nuclear display or a discrete graphics card not higher than 1,000 yuan, low power, recommended power supply rated about 300W.
2, the mid-end game platform: the use of quad-core processor + no more than 2,000 yuan of discrete graphics, you can play online games and play some small 3D games with less special effects, the whole machine power consumption is about 200-300W It is recommended to select a rated 450W~650W power supply.
