Intel wants the new ATX12VO power supply standard to be widely supported by upcoming Alder Lake-S processors. This is evident from a document in the hands of the tech site VideoCardz.
He. She Document from VideoCardz Among other things, outlines the ATX12VO certification process by manufacturers of motherboards and power supplies. These producers must work with OEMs and ODMs by the end of this month to have these products ready in time for the Alder Lake release in the second half of this year. Sources from motherboard manufacturers confirm Intel’s interest in VideoCardz. At the same time, manufacturers of motherboards and power supplies themselves will be less interested in it The production of 12ATXVO products.
So, according to VideoCardz, it’s unlikely High end Alder Lake-S motherboards will receive support for the new ATX12VO standard. At the same time, the standard can be used more for low-profile motherboards, for example for use in pre-built OEM computers.
The ATX 12VO standard requires, among other things, a motherboard with a 10-pin connector for power, compared to a standard 24-pin connector. Additionally, users need an ATX12VO compatible power supply. This standard stands for “ATX 12 Volt Only,” which immediately demonstrates the process. ATX12VO power supplies only contain 12VRailroad, Where current power supplies also have bars for other voltages, such as 3.3V and 5V. This means that voltages lower or higher than 12 volts must be converted by the motherboard itself, rather than by the power source.
This increases the complexity of the motherboard, but at the same time the new standard should guarantee better efficiency. PC power consumption will be less with ATX12VO power supplies. Idle power consumption should be especially lower. Linus Tech Tips YouTube Channel I posted a test last year With ATX12VO power supply and motherboard, which confirms low idle consumption.
