Perhaps many people think that Intel is just a CPU seller, but as a semiconductor giant, Intel has penetrated into all areas of PCs, and has also developed a considerable number of standards, such as ATX power standards, in the past, Intel has also worked with partners to continuously adjust the corresponding standards for graphics, CPU and other power supply monsters to guide power manufacturers to launch and manufacture corresponding power supplies. Intel officially released the new ATX 3.0 standard specification just last night, which can be said to be the biggest change in 19 years.
Considering that the power supply standard will affect the hardware development and manufacturing in the next few years or even more than a decade, the ATX standard always has the meaning of being ahead, and this time ATX 3.0 is also the same. The first is the power supply of 12V, in the latest ATX 3.0 standard, it adds a 12VHPWR 16-pin interface, equivalent to the 12Pin power supply interface and the signal interface of 4Pin, through the PCIe 5.0 transmission channel can provide up to 600W of power supply, of course, the premise is that the 4Pin signal needs to be connected with the graphics card to meet the transmission of data, in addition, Intel also said that with the help of the signal interface, the power supply can provide different power, such as even 12Pin power supply, 450W, 300W or 150W power supply interfaces are also available.
In addition to this 12VHPWR interface, the second is to provide a power supply standard for PCIe 5.0 expansion cards, so that PCIe 5.0 expansion cards can run stably, after all, with the increase in power consumption of external devices, this is also a power supply scenario that has to be considered. In addition, it is the stability of the power supply interface, such as how many times the power supply is switched, and the power supply efficiency under low voltage. In addition to ATX 3.0, Intel also introduced the ATX12VO 2.0 power standard, replacing the current 24Pin motherboard power supply, making the motherboard cable more concise, but for the motherboard designers are more demanding.
At least now it seems that the flagship graphics card in the second half of the year should have a relatively large increase in power consumption, and the use of a new power supply interface may be a good choice at this time, after all, 3 8Pin interfaces on the graphics card is really a headache.
