Intel wants to motherboard vendor to adapt its ATX12VO power connector to better support Alder Lake

Intel has been pressing hard for motherboard vendors to adopt the ATX12VO power connector on future Intel 12th Gen Alder Lake LGA1700 motherboards. Its been a year since intel is pushing the 10-pin power connector to replace the conventional 24-pin power connector on modern motherboards.

The 10-pin connector in question will ditch the 3.3V and 5V rails and only maintains the 12V rail. A more compact power connector minimizes power supply production costs, as well as cable clutter for the end-user. on the other hand, motherboard manufacturers even after implementing the 12V pin power connector will have to implement DC-to-DC converters on their motherboards to transform the 12V voltage down to usable 3.3V and 5V voltages. Since many components still use them.

According to Intel, the ATX12VO is more power-efficient at idle or low power loads and has a 20W load and its 500W 80 PLUS Gold power supply offers a power efficiency of up to 83%, compared to an ATX 500W 80 PLUS Gold unit’s 64%. Alder Lake features a hybrid combination of high-performance Golden Cove cores and low-power Gracemont cores.

According to sources, Intel is very committed to the ATX12VO power connector, but the power supply and motherboard vendors aren’t very fond of the idea. The power supply and motherboard vendors would have to sacrifice and ultimately redesign their best power supplies and best motherboards to embrace the ATX12VO standard, which cost both money and time.

We still don’t know as to whether the power supply and motherboard vendors will accept the intel’s push for a 12-pin power supply connector. However, let’s hope that Intel’s ATX12VO power connector sees more success than Nvidia’s 12-pin PCIe power connector. Only time will tell whether the ATX12VO will ever become a mainstream power connector, for now, the other standards are pretty well established in the market. for more updates, stay tuned.
