At the beginning of last year, Intel officially released the ATX12VO power supply specification and will give up support for the old 3.3V and 5V, and only focus on 12V. Intel hopes that the ATX12VO power supply standard can help desktop computers meet increasingly stringent government power consumption standards and environmental protection requirements while improving the power efficiency of the computer host. In fact, according to the test, the effect is still obvious, and the power consumption of the system is greatly reduced when the system is idle.
In the new specification, Intel abandoned the 24Pin interface in the original motherboard and recreated a new 10Pin interface with a pure 12V input. The original 3.3V and 5V are handed over to the motherboard for voltage conversion, and then output. For ordinary users, this can greatly simplify wiring.
According to VideoCardz, Intel is still committed to promoting the ATX12VO power supply specification on the upcoming Alder Lake-S processor. In the relevant instructions issued by Intel to manufacturers, it is pointed out that if you want to prepare motherboards and power supplies compatible with the ATX12VO power supply specification when Alder Lake-S is launched, you need to prepare related work before the end of May.
However, motherboard manufacturers and power supply manufacturers generally do not accept the ATX12VO power supply specification and are unwilling to participate in it. This is also easy to understand because, in order to adapt to the ATX12VO power supply specification, manufacturers have to redesign their own products, including the best motherboards and power supplies, which not only wastes money but also takes time. It is reported that some entry-level motherboards and OEM manufacturers may adopt the ATX12VO power supply specification because it can meet the more stringent power consumption standards of governments around the world. In fact, the XPS 8940 desktop computer currently sold by Dell is already using the ATX12VO power supply specification.
