Intel is shaking things up with Alder Lake, as it looks like its new CPUs will be up and running later this year. Not only is the architecture configured to mix high- and low-power cores with the latest memory standards, but you’ll also see an influx of Intel ATX12VO power supplies.
According to a document sent to Videocardz, and claimed to be from Intel, Intel hopes to influence manufacturers towards its new more efficient PSU standard at the time of the release of Alder Lake CPUs. To do so, it should give manufacturers an approximate delivery time of four to five months, so it is pushing OEMs to start work later this month.
This would suggest a September to October release at Alder Lake. November also remains a possibility.
Last year Intel launched the ATX12VO Desktop Power Supply Design Guide, a list of specifications, rules, guidelines and more for your new power standard. It was effectively proposed to introduce a new, more efficient low-load power supply, which is where current power supplies, while efficient at medium or high load, do not work as well when low power demand of 10%. This makes these PSUs more hungry than they should be when your PC is idle.
The new PSUs would deliver only a single 12V juice rail for added efficiency, leaving the rest of the power rails (for storage and some peripherals) on the motherboard. This requires a rethink and redesign not only for PSU manufacturers, but also for motherboard manufacturers.
For this reason, ATX12VO PSUs are not expected to immediately replace the multi-rail PSUs of today's computers. At least not in the short term. In any case, the ATX12VO standard will appear first in pre-made and high-energy machines. If you’re building a new gaming PC, you’ll want one of the best PSUs for PC gaming and you’ll be in luck because we just gave this guide a new review in 2021.
But that doesn’t mean our gaming PCs couldn’t be activated one day. Anything that makes these machines less energy hungry seems good to me.
