from completed build FLIP VIII | R7 5700X3D | RTX 4070S
At current retail prices, the B550 Tomahawk is a much better value than the launch MSRP. It has a fairly standard feature set, but is unfortunately lacking in I/O in comparison to similarly priced AM4 motherboards.
Pros:
- aesthetics; I like the industrial look of the heatsinks.
- storage; 2x M.2 slots, 6x SATA ports
- Flash BIOS button
- internal USB-C header for case I/O
- power delivery; 10 phase 60A power stage VRM
- audio; Realtek ALC1220P Codec
Cons:
- lackluster rear I/O; only 5x USB-A ports and dual LAN ports, space that otherwise could have been used for additional USB ports.
- lack of dedicated Clear CMOS button
- no onboard WiFi / Bluetooth

Has yet to even hiccup at the stuff I have thrown at it. Owned since 2021 and it still feels like its brand new, one of if not THE BEST midtier motherboards on the market!

from completed build 2020 “pre”-covid build “stuff was just starting to hit the fan”
For a higher tier B550 board, it was perfectly reliable and got the job done and then some. Fully recommend.

OK, for the price it should really come with WIFI, but its not a deal breaker.

This motherboard is great. I like the option to disable the RGB, but I haven't needed it because it adds a nice glow bellow the GPU. The motherboard looks good in my opinion.

Only nitpick is that I wish it had a few more USB headers. Otherwise, great motherboard if you know you won't need bluetooth or Wifi.

Great motherboard! Small amount of light that gives it a nice glow. Plenty of USB ports! Nicely fits with my build, very happy with this!

from completed build 5800X3D + 4070 SUPER
Good board, RGB is not great since all it does it light up the front panel connections on the bottom of the board. I've disabled it with the handy switch built onto the board.

from completed build c:/BOOBLESS
if you don't care too much about wifi or bluetooth, this is a beautiful, sturdy motherboard with incredible functionality. the 2 aRGB headers lend themselves to a lot of creative freedom with flashy builds. TONS of usb and fan headers for fancier builds as well. the m.2 slots are lightning fast if you pair them with good hard drives.
