Aiming for a mid-range PC can still provide impressive results with the B660 chipset and Intel 12th Gen Alder Lake processors. We've rounded up the best budget B660 motherboards to lay the groundwork for your next build with a variety of sizes and feature sets.
Gigabyte DS3H B660M AX
Best overall
Onboard Wi-Fi 6 (802.11ax) and 2.5G LAN for super-fast networking pair with decent VRM and modern connectivity for a fantastic value B660 choice. PCIe 4.0 slot, USB-C 3.2 Gen 2, and two M.2 sockets provide plenty of expansion options on the B660M DS3H AX.
ASUS Prime B660M-A D4
Best alternative
Dropping the wireless on this ASUS Prime alternative, you still have a PCIe 4.0 slot for a modern GPU and USB-C 3.2 Gen 2 support next to two M.2 sockets. High-quality heatsinks make for reliable cooling and safe overclocking with the B660M-A D4.
ASUS Prime B660M-A WiFi D4
Wireless variant
If Wi-Fi is a must, you can push the budget up a touch and pick the wireless variant of the Prime B600M-A D4 from ASUS. Enjoy 2x2 Wi-Fi 6 (802.11ax) and Bluetooth 5.2 for cable-free networking and device management on top of its feature set.
Gigabyte DS3H B660M
Cheapest option
As cheap as it gets without sacrificing reliability, this AX-less B660M DS3H variant drops the Wi-Fi support from our best overall board but keeps the rest. Still touting 2.5G Ethernet makes this a mean choice if you can connect to your network via LAN.
ASUS Prime B660-PLUS D4
Budget breaker
On the higher end is the Prime B660-PLUS D4, pushing affordability but still a fantastic ATX choice. A PCIe 4.0 slot, three M.2 sockets, USB-C 3.2 Gen 2, and Thunderbolt 4 support make it a connectivity king. It's big, so check your case size first.
ASRock B660M PRO RS
RGB light show
True gamers need RGB, or so we've heard. The B660M PRO RS supports DDR4 RAM up to 5333MHz overclocked and features an 8-phase VRM. PCIe 4.0 and two M.2 sockets are available for expansion, including M.2 Key-E for Wi-Fi addition.
Choosing the best budget B660 motherboard
A decent motherboard is the foundation of a custom PC even when you're looking to save some cash, so high-quality components are critical. In the B660 chipset range, Gigabyte comes out on top with its DS3H B660M AX board offering the best range of features for a fair price. Even better if you don't need Wi-Fi built-in, since the cheapest board on our list is a variant of that same Gigabyte model.
For those aiming for a full-size build, the Prime B660-PLUS D4 is an ATX board from ASUS with plenty of options for storage expansion and modern GPU support via its PCIe 4.0 lane. ASRock even accommodates RGB-loving gamers with their B660M PRO RS, touting 8-stage power phases for overclocking. Compared to some of the best motherboards available, any of these budget B660 boards can take you a long way if you don't mind sticking with previous-generation DDR4 memory.
