Now that it has been installed or upgraded to a new platform, given that the tenth and eleventh generations of high-end, high-level electricity consumption (not heat tdps) have reached about 200 w, and that the power of the medium-high-end graphic card is around 300 w, plus other accessories, the power of 600 w+ power, which was previously felt to be beyond the scope of attention, became a necessity. But looking at these power sources shows something confusing, so let's talk about it today。
As we mentioned earlier, the 12v power supply in computers is now the most important, and it is believed that many small partners will also be concerned, and then find that some of the 12v output of electricity is essentially the same as the overall supply. Is the other equipment useless? It's actually about the internal design of power. In the old structure, the 5v+3. 3v, which is still important, has dedicated circuits for generation, and 12v, although increasingly valued, usually reaches a total power of 80 to 90 per cent。
In the new architecture, because of the increasing importance of the 12v, all designs revolve around the 12v power supply, 5v and 3. 3v are at the end of the circuit and are obtained on the basis of the computer's need for pressure relief, so the maximum power of the 12v is, of course, almost the total power. That's right, the difference between it and atx 12vo is that it dares to abandon the old voltage, which is a "doorside." as for options, as long as the 12v meets the needs of all, the old and the new structures will not be very different。
Another question is why the total supply of 5vs and 3. 3vs is so small as the sum of their individual electricity supply. This is also related to the power structure, where 3. 3v of the current majority of the power supply is a 5v power relief, and only the maximum power of any voltage is measured by crowding out the power of another voltage, so the maximum total power is certainly less than the sum of the single maximum power. Moreover, in the new structural power source shown above, as the power supply is reduced to 5v power and then 3. 3v, the maximum current of the two is fully consistent and the power of 5v is essentially the same as the maximum total power of both。
Many small trenches partners may also find an interesting problem when they select to purchase, and there does not seem to be a supply of 900 w or 950 w between 850 w and 1,000 w. Of course, there are models, just because the power supply in this class is the same as the one in 1000 w, but apparently not as bright as the one in the kilowatt, plus the price space and market demand between 850 w and 1,000 w and higher power, so production and sales are small。
