In preparation for the launch of Intel’s Alder Lake later this year, the company has been trying to convince manufacturers to move to its more energy-efficient ATX12V0 power standard, ready for to these 12th generation monster CPUs. But because this would involve major and potentially uncomfortable changes for motherboards and PSUs, Intel has encountered a "united front of rejection" on both sides.
The proposed power standard would deliver only a single 12 V DC lane through a 10-pin connector, as opposed to the 24-pin AC standard, but would require a revision. complete of motherboard designs and components. It is potentially expensive. Reports from Igor Laboratories (via Sweclockers) consider the concern related to compatibility issues and the potential to cause significant industry-wide loopholes.
There is, therefore, a real reluctance to move away from the current 25-year rule. Not only are manufacturers dissatisfied, but they also cite users who have recently purchased high-performance PSUs that could be easily reused in future PC versions, they are also unlikely to accept the changes.
Want to buy a whole new and probably more expensive power supply, as well as a new mobo just for Intel Alder Lake? No thankyou.
Given that the first round of Alder Lake S CPUs is slated for release in late October / early November with the K and KF models, along with the Z690 motherboard chipset, it doesn’t look like the power standard gain a lot of traction before then.
Perhaps by the time the rest of the training is launched around CES 2022, along with the H670, B660 and H610 chipsets, there will have been an agreement, otherwise this could end up being a great job lost by Intel.
