As soon as upon a time, the elements in your PC required all kinds of voltages. The ATX normal defines 3.3V, 5V, and 12V connections in addition to -12V and 5V standby energy connections. Solely a few of that is really used at this time. Just about all fashionable PC elements simply take 12V and convert it to no matter voltage their elements really require. This is because of each developments in energy supply circuitry and the truth that most fashionable PC elements require sufficient energy that delivering the present over 3.3V or 5V turns into problematic.

ATX12VO is an Intel normal, so that you won’t anticipate it to look on AMD motherboards. Properly, you would be mistaken—ATX itself is an Intel normal, in spite of everything. The primary firm to indicate off a Socket AM5 motherboard designed for ATX12VO is MSI, who has at the very least a pair of boards on the way in which: the MSI PRO B650 12VO WiFi for Socket AM5, and the MSI PRO H610M 12VO for LGA 1700.
Each of the upcoming motherboards look like entry-level choices, nevertheless it most likely would not matter as a result of they are not more likely to seem on retailer cabinets both manner. MSI advised the location that the upcoming {hardware} is primarily aimed toward system integrators, and that it’s going to additionally offer its own-branded energy provide to associate with the brand new motherboards. In spite of everything, you’ll be able to’t run ATX12VO off of a typical ATX PSU.
Certainly, that is why ATX12VO hasn’t actually penetrated the market regardless of being unveiled in 2019. There are actually no downsides for customers—you find yourself with cheaper and extra environment friendly energy provides, cooler-running and quieter techniques, and drastically much less cabling to handle. It is potential that ATX12VO motherboards could possibly be barely dearer than normal ATX boards, however pretty unlikely because it’s a lot simpler to step down from 12V to 5V or 3.3V on the motherboard if crucial, and in any case the price ought to equalize. Hopefully we see extra ATX12VO adoption within the DIY market in 2024.
