Recommended 400W+80+ silent power supply

If you are looking for mute, I recommend you to look at the power supply of Annette or Haiyun. Many Annemes are magnetic bearings, which have a good mute effect. Haiyun has patented mute circuit technology, but the price is high. The pirate ship is also very good, 12CM fan, double ball bearings and active PFC. As for the power cord, if it is not long enough, buy an extension cord, which is available in Computer City, and it costs 2 yuan each. Generally, 350W can save electricity under the same power consumption output as 450W, because most power supplies need to consume more than 80% to achieve the best conversion efficiency. I don't know the brand of extreme cold, so it's hard to evaluate.
