ASRock B550 Phantom Gaming Itx/ax vs Asus ROG STRIX B550-I GAMING? - CPUs, Motherboards, and Memory - Linus Tech Tips
August 27, 2020 - I'm planning a new build inside the NZXT H1 with a 3900x (or the Ryzen 4000 equivalent), 32gb cl16 16-16-16-36 bdie 3600mhz ram, and a B550 mini-itx motherboard. Because I want a board that has a USB-C header for the H1 case, my options are between the MSI MPG B550I GAMING EDGE WIFI, ASRock B550 ...

Asus ROG Strix B550-I Worth the extra $50 over the ASROCK Phantom Gaming?
FWIW I got my Asus B550i from amazon warehouse for $190 and it was basically a returned item that hadn't even been opened it seemed. At that price it's an easy pick over the Asrock imo for the much nicer BIOS alone. More on reddit.com

ASUS ROG STRIX B550-I Gaming Mini-ITX Motherboard Review | KitGuru

r/sffpc on Reddit: Asus ROG Strix B550-I Worth the extra $50 over the ASROCK Phantom Gaming?
April 8, 2022 -

I bought the ASROCK B550 Phantom Gaming for my Meshlicious build (5600X, ROG Strix 3080), but I'm having second thoughts about whether I should exchange it for the Asus ROG Strix B550-I. The ASROCK is $50 cheaper right now and it didn't seem like the Asus had much to justify the price difference beyond brand reputation/recognition and aesthetics. My main hesitation is I've never owned an ASROCK motherboard and have read mixed things over the years. It sounds like most of the ASROCK sensor issues have been resolved, but I haven't found much about that lately. I use the PC for work from home a couple of days a week, so reliability and customer service are important for me.

The Gigabyte isn't a consideration because I will use the front USB-C frequently and it doesn't look like the MSI is compatible with my cooler.

Any thoughts from experience with either one? Thanks!

r/sffpc on Reddit: Asus, MSI, Gigabyte, ASRock B550i: What exactly are the differences between these ITX boards?
September 5, 2020 -

I'm planning to build a new PC using an ITX motherboard and a B550 chipset. Due to its niche, there thankfully are only a few boards to choose from... but I can't see many major differences between them.

So far I've found these unique attributes:

Asus STRIX B550-I GAMING ($219, Amazon) Gigabyte B550I AORUS PRO AX ($179, B&H) MSI MPG B550I GAMING EDGE WIFI ($199, Amazon) ASRock B550 Phantom Gaming-ITX/ax ($199, Amazon)
- Offers two PCIe 4.0 m.2 slots (Others have just one 4.0 and one 3.0) Mistake; it only has one PCIe 4 m.2 slot like the other boards. - Uses a higher end audio processor compared to the others (no data though) - Has a large selection of audio jacks - Has basically nothing good worth mentioning??
- Fan on chipset (not always on) -All USBs in the back are 3.2. Also, more display connections. -Fan and heatpipe on m.2 slot -Cannot flash bios without CPU/RAM
-No PCB LEDs -Has no internal USB-C Header - Has severe compatibility issues with heatsinks without mentioning it it. Also a hidden CMOS Jumper behind the IO. - (Kitguru) VRMs and CPUs tend to be hotter with this board. Perhaps due to higher clock speed?

Overall, I'd probably pick the Gigabyte board since I do enjoy better audio, and likely wouldn't use the extra featues that the other boards offer. It is suspiciously cheap though... then again, it isn't sold on a major online store like Amazon.

Are there any other features in these boards that I'm not aware of?Any info is helpful!

February 2, 2025 - As with all ITX boards, you do have to compromise with the functionality to some extent, however. The B550 Phantom Gaming ITX/AX is limited to two DIMM slots and, of course, a single (reinforced) PCIe slot for your graphics card.
