Long full-load work needs a strong power delivery and room for storage. Every pick uses a high-end X870, X670E, Z890 or Z790 chipset, ordered by M.2 slot count.

The order reflects M.2 slots, wired LAN and wi-Fi from maker specifications; we did not test these motherboards ourselves, and a missing wired LAN is flagged, not filled in.

Most M.2 Slots1 of 5

ASUS ROG Strix Z890-E Gaming WiFi

The Strix Z890-E lists seven M.2 slots, an 18+2+1+2 layout and Thunderbolt 4.

Best for

Buyers who put M.2 slot count first.

Skip if

Pass if a published wired network speed matters; this one has none.
ASUS ROG Strix Z890-E Gaming WiFi

Why we like it

It is the most expandable board here. On M.2 slot count it leads this guide at 7, ahead of the Z790 Tomahawk MAX (5). No other pick in this guide offers 18+2+1+2 power stages; compare the Z790 Tomahawk MAX, which has 16+1+1 power stages.

No other pick in this guide offers an LGA1851 socket; compare the X870 AORUS Elite, which has an AM5 socket. You get a Z890 chipset here, which sets it apart from the TUF X870-PLUS and its an X870 chipset. It also comes with AI overclocking, cooling and networking tools.

It uses Intel's LGA1851 socket for Core Ultra 200S processors, not older 12th to 14th Gen chips. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. Only the Strix Z790-E came close to it on price at the time of writing; it cost the most of the 5 picks.

Skip if

Skip it if this is a deal-breaker for you: m.2 slot count of 5, behind the Strix Z890-E (7).
MSI MAG Z790 Tomahawk MAX WiFi

Why we like it

It is the most complete Z790 board for its price here. On M.2 slot count it ties with the Strix Z790-E at 5. 16+1+1 power stages is unique to it among these picks, while the TUF X870-PLUS uses 16+2+1 power stages.

It shares an LGA1700 socket with the Strix Z790-E; the Strix Z890-E goes with an LGA1851 socket. It also comes with Bluetooth 5.4 alongside Wi-Fi 7 and a PCIe 5.0 graphics slot. It uses Intel's LGA1700 socket for 12th, 13th and 14th Gen Core processors; check the CPU support list for the BIOS version your chip needs, since early boards shipped before 14th Gen launched.

Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. It was the cheapest of the group when we checked; the X870 AORUS Elite was the next step up.

Choose another pick if you can't accept this: wi-Fi 6E rather than Wi-Fi 7.
ASUS ROG Strix Z790-E Gaming WiFi

Why we like it

It is the premium LGA1700 board here. It matches the Z790 Tomahawk MAX on M.2 slot count (5). No other pick in this guide offers a wi-Fi 6E; compare the X870 AORUS Elite, which has a wi-Fi 7.

Strong Alternative4 of 5

GIGABYTE X870 AORUS Elite WIFI7

The X870 AORUS Elite pairs four M.2 slots and USB4 with Gigabyte's five-year warranty.

Best for

Buyers who want EZ-Latch for tool-free card removal.

Skip if

If budget leads, the Z790 Tomahawk MAX was cheaper at our last price check.
GIGABYTE X870 AORUS Elite WIFI7

Why we like it

It is the X870 board with the longest cover here. It matches the TUF X870-PLUS on M.2 slot count (4). Like the TUF X870-PLUS, it has an AM5 socket, while the Strix Z790-E uses an LGA1700 socket.

It also offers EZ-Latch for tool-free card removal and a PCIe 5.0 graphics slot. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. When we checked, only the Z790 Tomahawk MAX cost less, and the TUF X870-PLUS cost more.

How We Chose These Motherboards for Heavy Workloads

Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

What we compared
We lined up five boards on M.2 slot count, wired network speed, wi-Fi and power stages, using each maker's published specs. We did not test them in-house, and wired network speed and power stages are missing for at least one pick.
What every pick has in common
All 5, from the Strix Z890-E to the TUF X870-PLUS, state M.2 slot count, wi-Fi and form factor.
Where the specs have gaps
The Strix Z890-E gives no wired network speed; the X870 AORUS Elite gives no power stages.
Price range
At our last check the picks ran from the Z790 Tomahawk MAX ($150 to $250) to the Strix Z890-E ($250 to $500).
