Yes, the ASUS ROG Strix B550-F Gaming WiFi II is worth its £139.99 for anyone upgrading a PC that already has an AMD Ryzen 3rd Gen processor on socket AM4, because the chip and the DDR4 modules you own drop straight in and Wi-Fi sits on the board rather than on a card. 3,685 buyers have rated it 4.6. Nothing else in the case needs replacing: the same 24-pin power supply plugs into the same header. It is not the right board for a machine built from nothing in 2026. This AM4 board takes DDR4 to a 128 GB ceiling and stops at Ryzen 3rd Gen, so a fresh build would spend the same £139.99 closing a platform off rather than opening one. Buy it to finish a PC you already have, not to start one. ## How many ports does the ASUS ROG Strix B550-F Gaming WiFi II have? Fourteen ports at £139.99 works out at £10.00 a connection, and the split is: 11 USB sockets, one of them USB 2.0, six SATA 3 ports for drives, two PCIe slots, one HDMI output and one optical S/PDIF connector for sound. A keyboard, a mouse, a headset, a microphone, a phone cable and an external drive can all stay plugged in at once, which is what that £10.00 a port actually buys on a desk. The ASUS ROG Strix B550-F Gaming WiFi II also takes 128 GB of DDR4 across four DIMM slots and posts a memory speed of 2133 MHz. Four slots leaves room to add a second pair of sticks later instead of replacing what you have. The main power connector is the standard 24-pin type, so a modular supply already in the case needs no adapter. ## What comes in the box with the ASUS ROG Strix B550-F Gaming WiFi II? One item: the board. The processor, the DDR4 memory, the cooler and a 24-pin power supply are separate buys, so the £139.99 buys the ATX board alone, with Windows 11 as the platform it runs. Budget for those four parts before ordering if you are moving an old PC across. Living with it is simple once it is mounted. Wi-Fi is built into the board, so a PC in a room without a network socket still gets online, and the single Ethernet port covers the wired setup when a cable is within reach. The HDMI output drives a display when the processor has integrated graphics, and the optical S/PDIF connector feeds a DAC or an older surround system while the two PCIe slots stay free for a graphics card and a capture device. ## What does the ASUS ROG Strix B550-F Gaming WiFi II get wrong? The socket is the real cost. AM4 pairs with Ryzen 3rd Gen and DDR4 and takes nothing newer, so the ASUS ROG Strix B550-F Gaming WiFi II is the last processor upgrade this PC will ever take. Anyone who plans to move to a newer Ryzen chip later pays twice, once for this board and again for a new one. It also costs more than the same-socket alternative. At £139.99 it sits £40.00 above the £99.99 MSI MPG B550 Gaming Plus, and £12.00 above the £127.99 ASUS TUF Gaming B650-Plus WiFi, which takes AM5 chips and DDR5. The 128 GB ceiling is generous for games now, but the MSI B850 Gaming Plus WiFi boards on the same shelf double it. ## Which board should you buy instead of the ASUS ROG Strix B550-F Gaming WiFi II? Against the MSI MPG B550 Gaming Plus at £99.99, the ASUS ROG Strix B550-F Gaming WiFi II asks £40.00 more for the same socket and the same DDR4. What the £40.00 covers is on this board: Wi-Fi without a card, 11 USB ports and six SATA 3 ports for a stack of drives. Take the MSI when the PC sits beside a network cable and two drives is the whole plan; take this one when the desk is crowded and the case is full. Against the ASUS TUF Gaming B650-Plus WiFi at £127.99, this board is £12.00 dearer and a platform behind, because that one takes AM5 processors with 128 GB of DDR5 and a PCIe 5.0 M.2 slot. A new build should go that way. The ASUS ROG Strix B550-F Gaming WiFi II is the better call only when the Ryzen 3rd Gen chip and the DDR4 sticks are already sitting on the desk, because then nothing gets bought twice. ## Specification | Field | Value | |---|---| | Listing title | ASUS ROG STRIX B550-F GAMING WIFI II ATX Motherboard Socket AM4 AMD B550 Chipset -90MB19V0-M0EAY0 | | Brand | ASUS | | CPU socket | Socket AM4 | | Compatible devices | Desktop PC | | RAM memory technology | DDR4 | | Compatible processors | AMD Ryzen 3rd Gen | | Chipset type | AMD 550X | | Memory clock speed | 2133 MHz | | Platform | Windows 11 | | Model name | ROG STRIX B550-F GAMING | | CPU model | None | | Processor Socket | Socket AM4 | | Memory Storage Capacity | 128 GB | | Ram Memory Maximum Size | 128 GB | | Main Power Connector Type | 24-Pin | | Graphics Card Interface | PCI Express | | Available Memory Slots | 4 | | Number of Ports | 14 | | S/PDIF Connector Type | Optical | | System Bus Standard Supported | SATA 3 | | Total SATA Ports | 6 | | USB 2.0 | 1 | | Total USB Ports | 11 | | Number of Ethernet Ports | 1 | | Total HDMI Port | 1 | | Total PCIe Ports | 2 | | Chipset Family | AMD B550 | | Model Number | ROG STRIX B550-F GAMING WIFI II | | Manufacturer | Asus | | Global Trade Identification Number | 04711081453314 | | Item Weight | 1 kg | | Manufacturer Part Number | ROG STRIX B550-F GAMING WIFI II | | Product Warranty | 3 Years Manufacturer | | Item Dimensions L x W x H | 23.4L x 4W x 30.5H centimetres | ## Questions people ask **What processor does the ASUS ROG Strix B550-F Gaming WiFi II take?** A socket AM4 processor from AMD's Ryzen 3rd Gen line. The chipset underneath is AMD B550, and the board runs Windows 11. Because the socket is AM4, newer processors do not fit it. **How much memory can the ASUS ROG Strix B550-F Gaming WiFi II hold?** 128 GB of DDR4 across four DIMM slots, with a memory speed of 2133 MHz. Four slots is what makes a two-stick upgrade sensible later, since you can add a second pair rather than replace the first. **How many SATA and USB ports does the ASUS ROG Strix B550-F Gaming WiFi II have?** Six SATA 3 ports and 11 USB ports, one of which is USB 2.0. Add two PCIe slots, one HDMI output and an optical S/PDIF connector and the board comes to 14 ports in total. **What comes in the box with the ASUS ROG Strix B550-F Gaming WiFi II?** The board on its own, counted as one item. A processor, DDR4 memory, a cooler and a 24-pin power supply are separate purchases, so plan them into the build before you order. **Does the ASUS ROG Strix B550-F Gaming WiFi II have Wi-Fi and Ethernet built in?** Yes. Wi-Fi is built onto the board, which is what the WiFi II in the name marks, and there is one Ethernet port for a wired connection. Both mean no network card is needed for the PC to get online. **What is the model number of the ASUS ROG Strix B550-F Gaming WiFi II?** The model number is ROG STRIX B550-F GAMING WIFI II and the manufacturer part number is 90MB19V0-M0EAY0. Either code identifies the exact board when you compare prices between shops.
