In fact, this 500w power supply only refers to the maximum output power, not to say that the power consumption of 500w is turned on as soon as the chassis is powered on. The specific power consumption can only be calculated according to the actual power consumption of other hardware in the chassis, such as CPU, graphics card, memory, hard disk and so on.

Power rationing in university dormitories generally refers to limiting instantaneous power. The maximum power of each university dormitory is different, but the minimum power is around 300w W W. As long as you don't play some large-scale games with high performance and high power consumption, it is no problem.

Extended data:

If you have to buy a desktop in an environment with limited power of 300 watts, the following scheme is recommended:

1, discrete graphics cards are often large power consumers, so you can't choose high-end graphics cards with hundreds of watts. Graphics cards above GTX 1660super100W should be the first choice. Although GTX 1650 and RX5500 have low power consumption, their performance is relatively weak.

2, CPU, most mainstream models are enough to meet the needs of students, a Core i3 and Ruilong 3 series CPU can get it, TDP power consumption is only a few tens of watts.

3. Try to choose those power supplies with high conversion efficiency, recommend those big brand power supplies with gold medal certification, and try not to save money on the more expensive power supplies.
