The history of the ATX power standard has been around for 25 years, and the classic connector on the motherboard with 24 contacts is familiar to anyone who has assembled a computer at least once. But soon the familiar connector, as well as the power supplies for the PC themselves, are waiting for major changes.
Intel announced the launch of the Advanced Technology eXtended 12-Volt Only (ATX12VO) standard before the end of this year. Unlike the usual 24-pin connector, it involves the use of a 10-pin connector and a transition exclusively to 12-volt lines.
The new generation of power supplies, in turn, will abandon lines with a voltage of 3.3 V and 5 V. Instead, the corresponding step-down elements will be integrated into the motherboard, which will also have SATA power connectors next to the interface ports.
It is expected that this approach will get rid of the connectors for additional processor power (with the exception of older and overclocker models). In addition, the design of the power supplies themselves will be simplified, which will no longer require a buck converter for 5V and 3.3V lines. It is expected that in the future, the transition to a new standard can also reduce the cost of equipment.
