What are the differences between the 16A and the 20A?
If the actual power is less than 500W, there is no difference between the 2 power supplies. If the power is greater than 500W, the 800W must be used.This is a matter of capacity, and 20A can do much more work than 16A does.
This is the +12V output current, and the 20A is stronger and more stable than the 16A.Buy power depends on your computer configuration, the CPU graphics card, hard disk, motherboard, memory, CD-ROM, mouse button, fan power all add up, the power rating power consumption than the actual power consumption of about 20% is appropriate.Too much is just a waste of money, and 800W itself doesn't cost much more than 500W, mainly because the computer consumes a lot of power.If your computer total power consumption is 400W, the actual consumption is 380W, then buy 450-500W rated power supply can be.In addition, the 20A is higher than the 16A version, and the 20A is a dual +12V output and is more stable.Buy according to actual needs.
16A, 25A three-phase four wire, to the specifications of the 440V voltage, but can use one of three holes, sometimes in order to meet the requirements of 3P air conditioning on the current is relatively large, so also can choose 16A, 25A three-phase four wire, but it belongs to the four eyes, connection time, as long as the use of the three holes you can rest, a space is of no use, then the four hole plug configuration 16a, 25A, the corresponding connection, can achieve high power or Guiji water heaters and other equipment.
Because the 10A and 16A of three three three and Jack 20A distance and size are not the same, the use of 10A socket plug is not ordinary insert 16A plug, also cannot use 16A common socket insert 10A. 20A three Jack more, 10A, 16A, socket and plug 20A, must use the corresponding.
Socket 10A and 16A and 20A, there is a difference between with and without switch switch, commonly used in the home appliance is 10A current (ordinary electrical plug has obvious signs, current home) is the most commonly used 10A five hole socket (10A) suitable for ordinary home appliances. Air conditioning socket (1.5-2P) is used as 16A, 2.5P-3P control cabinet, electric water heater power is likely to use 16A or 20A to the socket (the specific configuration of air conditioning air conditioning on how much current can plug wearing labeled to configure according to),
