Something that Intel is keen on introducing as part of its upcoming Intel Z690 motherboards for 12th Gen Core “Alder Lake” processors is support for a new power standard called ATX12VO that promises reduced idle desktop power for lower energy use. Recent reports suggest that many motherboard manufacturers couldn’t care less and have opted to retain the traditional 24-pin ATX12V specification for their upcoming products, however. According to one insider, Yuuki_ans, some manufacturers are merely offering ATX12VO to ATX12V adapter boards, while others, more humorously, have designed a single ATX12VO motherboard that won’t actually be released and exists solely to meet Intel’s alleged requirement that there must be at least one board supporting its new power standard. Two ATX12VO motherboards that are already available on the market are MSI’s Z590 PRO and ASRock’s Z590 Phantom Gaming 4SR.

绝大多数厂商选择保留传统的24PIN供电,只会有少部分型号推出12vo供电策略。
(有些厂商甚至拿出了12vo转24PIN的转接板)

据说intel要求主板厂商必须推出至少“一款”支持12vo供电的主板。 pic.twitter.com/W3HlLMTCEj
1. Intel AlderLake is the same as TigerLake's Xe, and will be used until the 14th generation.

2. Some manufacturers say that intel requires us to "make" at least one 12vo-powered motherboard, but they didn't say that we must "release" it. (Laughs🤣) pic.twitter.com/d9aCH0H7vP
Featuring support for Alder Lake Desktop CPUs, the Z690 motherboards were going to adopt the new standard which is shown to reduce idle power by half, but the power efficiency gains are not as significant as power increases all the way up to a full load. To get ATX12VO running, you would need a proper PSU & a motherboard with the necessary power connectors. This is just too much of an upgrade for existing users and could be one of the many reasons why motherboard makers are deciding against using the standard.
