I'm putting together a Ryzen 7 7800X3D system with an RTX 5070 in a DeepCool CH160 case and need a suitable Micro-ATX motherboard. My preferred features are the B850 chipset, four RAM slots supporting up to 128GB, built-in Wi-Fi and Bluetooth, and at least two M.2 slots. I've seen some worrying reports about certain boards or power cables overheating, so reliability is important. Since the nearest computer shop is a long distance away, I'd especially appreciate recommendations for brands and models with a good track record and fewer RMA problems.

A B850M Eagle or Aorus model should offer solid value for this setup. TUF and Mortar boards are also good higher-end choices, but their extra features probably aren't necessary for a 7800X3D.
The Gigabyte B850M Aorus Elite WiFi6E is worth checking out. It has the features you're after and is positioned as one of the more affordable higher-quality B850 Micro-ATX options.
Use a motherboard comparison tool and filter for B850, Micro-ATX, four memory slots, integrated Wi-Fi/Bluetooth, and two M.2 slots. That should narrow the list quickly and let you compare prices, power delivery, and warranty support.
There isn't anything inherently wrong with wanting B850, but make sure you're choosing it for features or upgrade support rather than assuming the chipset alone guarantees better reliability. A good B650 or B650E board could also be worth considering if it meets your requirements and costs less.
I mainly wanted B850 to have a newer platform and avoid compatibility surprises, but I'll compare it with well-reviewed B650 options too.
