i5-12500 vs i5-13500 - low power with Frigate 4k face recognition.

I currently have this set, but I want to buy something better for permanent face recognition for the main 4K stream from the camera, and in the future, more 4K cameras (20FPS). The goal here is to minimize power consumption.

Mobo:MSI B250M MORTAR

CPU:i7-7700

RAM:16GB DDR4 (1)

60TB HDD, 1TB nvme, 1TB SSD

PSU:BE QUIET! Pure Power 11 400W 80 Plus Gold

3x120mm FAN

Idle - ~22W.

Frigate 4k 20FPS record, 720p substream face recognition 12FPS + objects ssdlite_mobilenet_v2 model - igpu/openvino - ~26W.

Frigate 4k 20FPS record, 4k 5FPS face recognition - constantly jumps between 32W and 40W, which is too much. Especially when I add more 4K cameras, it will increase significantly.

In the future, there will be a trigger and HA, which will minimize power consumption even further, but we are focusing on continuous face recognition in 4K and power consumption. I would prefer to buy the i5-13500 because of the Intel UHD Graphics 770, but I am concerned about stability issues during C - am I right? Does anyone have this CPU, with which motherboard, and what is its power consumption from the wall when idle? I think the safest option is the i5-12500 with the same igpu, but the processor itself is less efficient and less future-proof.

I would like a motherboard with at least 6x SATA + preferably 2x m2 (I will accept 1x m2). Preferably with 2.5GbE Lan, because then I won't have to use my card and there will be an additional slot for SATA. DDR 4, because I have a lot of those chips.

I am initially considering the MSI MAG B660M MORTAR. I have no idea how this motherboard performs in terms of power consumption. Can you recommend any proven motherboards and how much power your sets consume from the wall?
