Course Introduction：1. How to calculate the power of assembled computer power supply? The power supply works relatively stably within the rated power. The peak value can be reached but it is easy. ggtdp actually refers to the thermal power. It is usually used to indicate how much tdp u the radiator can press. Generally, the silent frequency of the CPU is much lower than that of the marked tdp graphics card. The normal gaming power of 1066-1080ti is between 140w-250w, so if you want to replace the power supply, generally add cputdp + graphics card gaming power, plus 100w, and the resulting power is the rated power of the power supply you need. 2. How to calculate the computer power supply ? |Detailed explanation of computer power supply power calculation method When assembling or upgrading a computer, it is crucial to choose the appropriate power supply.

Course Introduction：The power bank can charge the power bank. Detailed introduction: When the user uses a power bank to charge the power bank, one of the power banks will be in a discharge state, while the other power bank will be in a charging state. If they are connected in reverse, the charging and discharging states will be reversed, and the charging state will be reversed. There will be "power loss" in the process. Although power banks can charge each other, if the cycle continues, the power that can be converted into the power bank will become less and less. , Therefore, this charging method makes no sense. It seems to be "brain-burning", but it is actually a "brainless" problem.
