Deal Details
YMMV — open-box, limited quantities, may sell out fast.

Open-box warning up front: open-box motherboards are a gamble — check the socket for bent pins and confirm all accessories are in the box as soon as it arrives, and be ready to return it if anything's off. Only buy if you're comfortable with that.

Best Buy has the ASUS TUF Gaming Z790-Plus WiFi (LGA1700, DDR5, WiFi 6E) in Open-Box Excellent condition for $79.99 with shipping available. For reference, a new one is $239.99 at Best Buy and $243.99 at Newegg, and Micro Center's open-box starts at $123.96 — so $79.99 is about 67% below the new street price.

Platform note: LGA1700 supports Intel 12th/13th/14th gen — great for a budget build with a used CPU, but it's not the current socket.

(For transparency: Walmart had this board at $75 as an in-store clearance back in June — long gone for most people and never shippable.)

Local pickup worked for me, bent pins bent anything I'll pass.

Z790 has 8xDMI 4.0
vs
the 4xDMI 4.0 you get on the B760
Since the "southbridge" handles twice the bandwidth. Your 10Gbps network ports, WiFi, sata, non cpu-direct nvme slots, and non CPU-direct pcie all share the bandwidth out of the chipset.

The chipset lanes aren't an issue with this particular board.

One PCIe 4.0 16x @ 4x, one PCIe 4.0 4x, and two PCIe 3.0 1x doesn't provide you with many expansion options. Even physically accessing anything besides the 16x @ 4x will be tough if you drop a 2.5 or 3 slot GPU in the 5.0 slot.

Also, not sure what you're talking about with the networking... this has a 2.5Gbe port.

Did you accidentally paste part of a chatgpt conversation where it hallucinated?

I picked one up last week. Dozens of bent pins. I returned it before I left the store.

THIS is why the only thing I wont purchase pre-owned is a Mobo. I am extremely frugal, but putting together a PC only to find issues with the mobo is a nightmare.

Nope.
Not hallucinated, though it probably would do this better.since I left the part out about my specific use case of using this specifically for a NAS build. and I utilized everything I could on the one I already made with this board, and I could use another one. FWIW I use the onboard 2.5GBe for Management, then use the PCIe x1 and x4 slots and the CPU direct M.2 slot with an PCIe x4 adapter for Prom21, 10GB NIC's and HBA's.

As to your limited connectivity options on the x1 and x4 slots, that is just not true. NIC's HBA. or thunderbolt all happily fit.

The newer low power RTL8127 Chipset based NIC has 10GB SFP+ or 10GBe on a PCIe 4.0 x1 and Lekou (sp?) has one that uses PCIe 3.0 on x2 (x4 physical) for under $50 on AliExpress.


But even a older server grade card like a Mellanox ConnectX with its dual 28SFP can use and negotiate on a PCIe 3.0 x1 to utilize up to 0.985GB/s or 7.88Gb/s. Sure it isn't True 10G, but the card will negotiate at 10G cage to module, and top out at 7Gb/s in transfers. The TUF's x4 slots will give you 3,94 GB/s or 31.51Gb/s - That is more than enough for 1 SFP28 port to hit 25GbE or both SFP to hit 10GbE. If you need to plug in a physically larger card into an x1 or x4 slot you can either tape off the card and cut the notch permanently into the card with a dremel, or less effort, use a fine tip soldering iron or even a knife held over a flame to press into the edge and pull away to melt away the end of the PCIe slot on the board so its open ended and can take any size card. There are no Caps in the way up to an x8 card on the top x1, the middle x4 can take a full x16 length, the bottom is limited again to x8 unless you are using the NVMe slot without or with a low profile heatsink.

I guess my point was if anyone was planning on using all the slots you have ~16GB/s to play with on the Z790 vs the B760 at only ~8GB/s among everything not on the x4 and x16 slots closest to the CPU.

Sure its an LGA1700 board, but that makes it cheap and quicksync and gaming work fine and the only thing Ultra has over it is AV1 encode.

Would be better if this was DDR4, as a DDR5 board you're locked into over-priced memory at which point go AM5 or LGA1851

Ddr5 boards seem to have bad resale value and seem to always be cheaper. Mylocal microcenter has wall full of AM5 returned motherboards. I guess people purchase and get home then contemplate how much they just spent on ram/build cosf and return everything. Just a guess.

Just returned mine, bent pins on CPU socket out of the box
