The straightforward way onto Intel's Core Ultra platform
Quick Specs
- Intel B860 chipset on LGA1851 for Intel Core Ultra Series 2 desktop processors
- Two DDR5 DIMM slots, dual channel, with XMP profile support
- PCIe 5.0 x16 graphics slot fed directly by the CPU
- M.2 sockets for PCIe NVMe storage plus four SATA 6Gb/s ports
- Micro-ATX board with 2.5 Gigabit Ethernet and modern rear USB connectivity
Current-generation Intel without the extras you will not use
LGA1851 and the Core Ultra Series 2 chips bring a genuinely more efficient Intel desktop platform, and the B860M-K is the cleanest way to get there. You get the PCIe 5.0 graphics link straight from the CPU, DDR5 with proper XMP handling, 2.5G Ethernet and the modern NPU-equipped CPU support that Windows increasingly leans on. For a South African buyer replacing an aging Intel machine, the efficiency gain is worth noting on its own: lower package power means a smaller cooler, a quieter case and less strain on the PSU you already own.
Honest limitations
This is the K variant, the leanest board in the Prime B860 line. Two DIMM slots rather than four means your memory capacity is fixed by the kit you buy at the start. There is no onboard Wi-Fi or Bluetooth, no Thunderbolt, and B860 does not allow CPU core overclocking, so a K-series chip runs at its stock boost profile. Power delivery is sized for mainstream Core Ultra 5 and 7 chips rather than the top of the range under sustained heavy load. If you want four DIMM slots, wireless in the box, or overclocking control, step up to a B860-A or a Z890 board.
FEATURES:
- PCIe 5.0 x16 graphics slot ready for next-generation cards
- DDR5 support with XMP profiles and ASUS memory training
- M.2 NVMe storage with heatsink coverage and Q-Latch tool-free mounting

Questions
Before you buy
Which processors fit this board?
It takes LGA1851 processors on the B860 chipset. Socket and chipset together decide what will run: the socket has to match physically, and the chipset decides which generations on that socket are supported. For a chip released after the board, check the manufacturer’s CPU support list to see whether a BIOS update is needed first.
Which cases will this board fit?
It is Micro-ATX. A case supports its own size and anything smaller - an ATX case takes ATX, Micro-ATX and Mini-ITX boards, a Micro-ATX case takes Micro-ATX and Mini-ITX. Each case we sell lists the board sizes it accepts under Specifications.
What memory does it take?
DDR5 across 2 slots, up to 128GB in total. DDR4 and DDR5 are not interchangeable - the notch in the module is in a different place, so the wrong type will not seat. Buy the memory as a matched kit rather than as single sticks wherever you can.
Is it in stock, and when will it ship?
Yes - this one is in stock. Order before 12:00 on a working day and it ships the same day; after that it goes out the next working day. We are open 09:00 to 16:30, Monday to Friday, so an order placed over a weekend or a public holiday ships on the next working day.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
