This standard ATX12VO ("O" says "Only", "only" in English) will force manufacturers to reuse their components, because + 33V and 5V rail is removed, which generates electrical energy just supply the +12V rail motherboard, graphics card, hard drives, etc. This obviously has its consequences in terms of construction.
Greet the 20 + 4 ATX wing connector
Another very important change at that level The 20X + ATX triangular connector has been removed power supplies, too replaced by a smaller 10 pin that will simply supply all the energy needed. However, 4 + 4 EPS connector connector is retained but will be optional
For its part, the train 5VSB (Standby) which uses devices such as USB peripherals to keep even the PC off, will be replaced by 12VSB, even though USB output will still be 5V by using the converter on the motherboard itself.
For SATA devices, such as 2.5 ″ SSDs that require 5V input, power will now be given to the mother board instead of connecting to the supply of electricity directly, so what Intel wants is that motherboards now have SATA power connectors mounted next to SATA data connectors to make this connection.
Should we buy another motherboard and an electric one?
As you can imagine, all of these changes proposed by Intel with the new ATX12VO standard include the redesign of both the electrical components and motherboards. But don't worry because right now, and even though a new standard has been released this year, we won't have to buy new things
Initially, the ATX12VO standard will only be used by system integrators, ie on OEM machines. The reason for this is because for a motherboard manufacturer, for example, making a change in construction is much easier if you already get an order from multiple units, which will make this change profitable. Intel may have remembered a charge that was previously determined by the BTX standard
Over the past few years, power equipment has already evolved their design to focus on AC-DC to 12V direct (12VDC) conversion, and then make small modifications from those 12V to 5V and 3.3V currently use. -ATX12VO will remove this last step, allowing the motherboard to make modifications (they already do).
All this Simplify the internal structure of resources and wires and connectors to use, so in theory it should lower your costs and greatly improve their performance (less power conversion, less power loss and great efficiency). Of course, as far as motherboards are likely to be complicated by their own electrical design.
