Plus its First ATX12VO PSU
Intel’s new (or revised) ATX12VO was first introduced back in early 2022, but it’s only now we’re starting to see some motherboards with this new standard being implemented. Let’s see how long before it becomes the norm.
Taken from TPU … MSI is planning to expand its small lineup of motherboards with ATX12VO power connectivity—the new desktop motherboard power standard that does away with the 5 V and 3.3 V power domains, and relies entirely on 12 V, with the aim of simplifying PSU designs and desktop PC power cabling. ATX12VO is still an emerging standard that hasn’t gained traction in the DIY channel, but PC OEMs and systems integrators are beginning to catch on, for the cost savings to be had. MSI has been targeting this class of customers—OEMs and small SI, with motherboards under its mainstream PRO series. For the Socket LGA1700, the company has the PRO H610M 12VO, and now the company has its first ATX12VO motherboard for AMD Socket AM5—the PRO B650M 12VO/WiFi.
The company hasn’t finalized the board design, but we know from its silhouette to be a Micro-ATX (240 mm x 240 mm) board, with the Socket AM5 wired to two DDR5 DIMM slots, a PCI-Express 4.0 x16, a handful M.2 NVMe Gen 4 slots, and some basic connectivity, including onboard Wi-Fi. As with all ATX12VO motherboards we’ve seen to date, onboard VRM is used to switch 12 V to lower voltage domains, including 5 V and 3.3 V needed for SATA drives, and the likes. MSI also revealed that it is working on a branded ATX12VO power supply series, so both the retail and OEM/SI channel customers can buy the motherboard+PSU as combos from a single source. Not much else is known about these PSUs at this point.
