Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Design and revisions : one component is produced by several partner manufacturers: cooler, backplate, RGB lighting and printing change with the version delivered.
  • Quantity : an image showing two memory modules or several fans does not mean the set is sold that way — check the packaging in the specifications.
  • Cooling : a processor may be sold without a cooler, and not all the fans visible inside a case are supplied.
  • Accessories : cables, adapters, screws, brackets and software licences are supplied only if the specifications say so.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

The slightest doubt about a specification? Contact us before ordering and we will check for you.

1 year warranty — free repair in Morocco if it breaks down during the warranty period

1 year manufacturer's warranty

This product is covered for 1 year by a manufacturer's warranty (the brand's official warranty). Your iris.ma invoice serves as the warranty document: keep it safe.

A problem with your product? Don't worry: contact us by phone, WhatsApp or e-mail. Depending on the brand, we direct you either straight to the repairer appointed by the brand to fix your product, or to us — and we take care of the rest.

  • If a repair is possible, it is carried out free of charge.
  • If the product cannot be repaired, the brand offers an exchange for another product.
  • If no product is available, a refund is issued as soon as the brand confirms it.

Faulty straight out of the box? Some brands offer an immediate exchange, others a repair. Contact us to find out what applies to your product.

The warranty covers breakdowns occurring under normal use, as defined by the brand's terms. Product breakage (drop, impact, liquid…) is not covered, nor are certain consumable parts.

Frequently asked questions about this product

Which processors does the ASUS TUF GAMING B850M-PLUS II support?
AMD Ryzen 7000, 8000 and 9000 series processors, on socket AM5 with the AMD B850 chipset. The board takes only one processor, and an AM4 Ryzen does not fit this socket.
How many M.2 SSDs can I install on this motherboard?
Three: one PCIe 5.0 x4 and two PCIe 4.0 x4, with NVMe RAID support. The Gen5 slot is the fastest — that is where the system SSD goes.
Is the rear panel of this motherboard corrosion-resistant?
Yes: it is pre-installed and made of stainless steel, and ASUS specifies a 72-hour salt spray test. This matters by the sea or in a humid workshop.
How much memory does this B850M motherboard support?
4 DDR5 slots in dual-channel, up to 8,000 MT/s and beyond when overclocked. DDR4 does not fit these slots: the connector is different.
How is the processor power delivery designed?
As a 14+2+1 phase design with 80 A power stages, on an 8-layer PCB and under enlarged heatsinks. Enough to handle the most power-hungry Ryzen processors under sustained load.
Do I need a screwdriver to mount the SSD or remove the graphics card?
No: the M.2 Q-Latch holds the SSD in place without screws, and the PCIe Q-Release lever frees the graphics card in one move, even under a large cooler.
Can I update the BIOS without a processor installed?
Yes: the BIOS FlashBack feature updates the board without a processor or memory installed, from a USB flash drive. This is what gets past a build refused by an outdated BIOS.
Can I connect my case's front-panel USB-C port?
Yes: a 10 Gbps USB-C header is provided for the front panel, in addition to the 20 Gbps USB-C port on the rear panel. Your case's port will not go unused.
Will this motherboard fit in a small case?
Yes: it is a micro-ATX form factor measuring 244 × 244 mm, shorter than an ATX board, while keeping PCIe 5.0 and three M.2 slots. It also fits in a mid-tower.
Is the graphics card slot reinforced?
Yes: the PCIe 5.0 x16 slot is fitted with ASUS SafeSlot reinforcement, which protects the connector from bending under the weight of a modern graphics card.
Can I connect a monitor to this motherboard without a graphics card?
Only if the processor has an integrated graphics core: the motherboard has no graphics controller of its own, it passes through the Ryzen's. Without it, a graphics card is essential.
What is the audio quality of this ASUS motherboard?
A Realtek ALC1220P codec with 7.1 channels and DTS processing. It is a higher-grade codec than the common ALC897: enough to drive demanding headphones without a sound card.
Is this ASUS TUF GAMING B850M-PLUS II motherboard new and under warranty?
Yes, it is a new ASUS product, reference 90MB1MT0-M0EAY0, barcode 4711636181853, with 2.5 Gbps wired networking and four SATA 6 Gbps ports. The invoice serves as the warranty document, for 1 year.
