ASUS sells more motherboard families than most makers, and the names tell you a lot once you know the code. ROG is the enthusiast range, TUF Gaming is the durable mid-range, Prime is the plain all-rounder and ProArt is built for creative work. This guide decodes the range so you can read any listing on our ASUS motherboard deals page and know roughly where the board sits.

The product lines, from top to entry
- ROG Maximus (Intel) and ROG Crosshair (AMD): the flagships, sold only on the top chipsets such as Z790, Z890, X670E and X870E. Within them, Extreme is the largest and most heavily equipped (often E-ATX), Hero is the standard ATX flagship, Apex is aimed at memory and CPU overclockers and has only two memory slots, and Formula and Gene appear in some generations.
- ROG Strix: the upper mid-range gaming line and the ROG boards most people actually buy. A letter after the chipset ranks them: -E is the best equipped, then -F, with -A usually a silver or white-themed board at a similar level, -G normally a micro-ATX board and -I the mini-ITX model.
- TUF Gaming: mid-range boards sold on durability and sensible features rather than lighting. -PLUS and -PRO are the usual tiers. TUF boards are a common sweet spot on B650, B850 and B760.
- ProArt: the creator line. These lean towards fast networking, plenty of high-speed USB and, on many models, Thunderbolt or USB4, with restrained styling. The exact ports vary by board, so check the listing.
- Prime: the mainstream range, from well-featured -A and -PLUS boards down to basic -K and -E micro-ATX models. If a board has no ROG, TUF or ProArt in its name, it is almost always a Prime or one of the plain business-style boards.
- Pro, Pro WS and CSM boards: business and workstation models. CSM stands for Corporate Stable Model, a version intended for companies that need the same board to stay on sale for longer. For a home build it behaves like the ordinary board.
How to read an ASUS model name
Take TUF GAMING B650M-PLUS WIFI. The family comes first (TUF Gaming), then the chipset (B650), then a size letter, then the tier (-PLUS), then extras (WIFI).
| Part of the name | What it means |
|---|---|
| M after the chipset (B650M, B760M) | Micro-ATX board |
| -I (B650E-I, Z790-I) | Mini-ITX board |
| No size letter | Normally full ATX |
| WIFI | Wireless and Bluetooth are built in. Without it, assume the board has wired networking only |
| D4 | A DDR4 version of an Intel LGA1700 board. The same name without D4 is the DDR5 version |
| II | A revised second version of an earlier board. The layout or ports can differ from the original |
| -CSM | Corporate Stable Model, as above |
The D4 suffix deserves care. LGA1700 boards take DDR4 or DDR5, never both, and the two versions of an ASUS board can look identical in photos. Our DDR4 vs DDR5 guide explains which to pick. AM5 and LGA1851 boards are DDR5 only, so the question does not arise there.
BIOS FlashBack
ASUS calls its update-without-a-CPU feature BIOS FlashBack. On boards that have it, you copy the renamed BIOS file to a USB stick, put it in the marked USB port, connect the power supply and press the FlashBack button. The board updates itself with no processor, memory or graphics card fitted. That matters when you buy an older-stock board for a newer CPU, which is common with Warehouse boards.
It is present only on some boards. Most ROG, ProArt and TUF Gaming models of recent generations have it; many cheaper Prime boards do not. Look for the button on the rear panel in the listing photos, or check the specification on the ASUS product page. The full picture is in our guide to BIOS updates and CPU compatibility.
Warranty and support in the UK
ASUS motherboards are generally sold in the UK with a three-year manufacturer warranty, but terms can differ by model and over time, so confirm on the listing or the ASUS support site. In practice the retailer is your first port of call for a faulty board, and with Amazon that usually means a return or replacement through your order page.
Boards from Amazon Warehouse are covered by Amazon's returns policy, and may not carry the full manufacturer warranty that a new board does. Check the terms shown on the offer before you buy, and test the board promptly using our used motherboard checklist. Support experiences with any large maker are mixed, and we hold no data that would let us rank one against another.
What to look for when buying
- Choose the socket and chipset first, then the family. A TUF Gaming B850 board and a ROG Strix B850 board run the same CPUs; the difference is ports, power delivery, M.2 slots and audio. See how to choose a motherboard.
- Read the whole model name. WIFI, D4 and II each change what you are getting.
- Do not pay for a Maximus or Crosshair unless you will use what it adds. Our guide to how much to spend covers where the extra money stops buying anything.
- Number of M.2 slots, USB4, WiFi version and PCIe 5.0 wiring all vary by board, not by family. Check the listing.
When you know which tier you want, compare current prices and price drops on the ASUS deals page.
Questions people ask
What is the difference between ROG Strix and TUF Gaming?
Both are gaming ranges. ROG Strix sits higher, usually with stronger power delivery, more M.2 slots, better audio and more lighting. TUF Gaming aims at the mid-range with fewer extras. On the same chipset both run the same processors, so choose on the ports and slots you need.
What does D4 mean on an ASUS motherboard?
It marks the DDR4 version of an Intel LGA1700 board. The same model without D4 takes DDR5. The two memory types are not interchangeable, so match the board to the memory you own or plan to buy.
Do all ASUS motherboards have BIOS FlashBack?
No. It is common on ROG, ProArt and TUF Gaming boards and missing from many cheaper Prime models. Check the specification for the exact board. Without it you need a supported CPU fitted to update the BIOS.
How long is the warranty on an ASUS motherboard in the UK?
Generally three years from the manufacturer on a new board, though you should confirm for the specific model. Deal with the retailer first. Amazon Warehouse boards fall under Amazon’s returns policy and may not carry the full manufacturer warranty, so check the offer terms.
