It’s been a few years since the alternative power supply standard ATX12VO was created, which is reduced to a pure 12V power supply, from which other voltages such as 3.3 V and 5 V are already generated by the motherboard itself. Among other things, this kind of power supply should have the potential to reduce idle consumption, which could perhaps be a little less distant from laptops. Until now, ATX12VO was mainly the domain of Intel, but now MSI has also produced a B650 board for Ryzen processors.
According to HardwareLuxx, MSI is now preparing some new boards that will use this type of power supply. Among them will be the Pro H610M 12VO model for Intel processors on the LGA 1700 platform, but another model marked MSI Pro B650 12VO WiFi is an AM5 board for AMD Ryzen 7000 processors (and later). It should be a full format ATX board.
HardwareLuxx learned about these boards during a field trip to MSI’s facilities in Taiwan. The company wants to launch them during 2024, and they will probably be on display next week at CES 2024. Due to the small distribution of ATX12VO in the retail component market, this board, along with the ATX12VO power supplies, will be primarily aimed at companies that assemble PCs (MSI demonstrated an assembly that used resource produced by FSP, but also preparing its own). It would be nice if they were also sold more widely, so that interested parties could possibly try out the claimed benefits of better energy efficiency.
It is said that ATX12VO sources could improve energy efficiency by up to 30% (but this will probably only apply to certain situations). In addition to low idle loads, there could be savings in higher loads as well, but there is also an advantage in the fact that the source can be reduced. With the ATX12VO standard, it could thus be easier to build powerful power supplies in the SFX size instead of the traditional larger “ATX” boxes.

If these kinds of power supplies and boards are to take off, then it’s positive that it won’t just be an Intel platform thing. Except for the differently solved location of the converters for the 5V and 3.3V branches (the wiring of which must be connected by cables to the connectors on the board), the ATX12VO does not change the concept of a desktop computer, so it is compatible with all cards, disks and cases and can coexist with traditional power supplies and boards. The only downside is that you can’t pair the board with an older source. The advantage of ATX12VO boards becoming commonly sold in retail would also be that it would be easier to upgrade OEM computers that will already be built on this basis.
Project Zero
In addition to the ATX12VO, MSI is also trying other new trends, including “Project Zero”, meaning motherboards that have moved the internal connectors for power, SATA, USB, front of the case or fans to the back of the PCB so that they flow directly into the cabinet space for cable management and cabling you didn’t have in the “tidy” lighted cabinet space. MSI should launch a range of these boards, including some model for AMD processors (B650M Project Zero).
More companies are experimenting with this (also Asus, for example) and it is possible that this style will become widespread in gaming PCs in the future. But it is complicated in that the connectors have to fit into the cutouts in the cabinet, so of course such a board has significantly limited compatibility.
