Nice motherboard with plenty of features
Bought this for my project of building a newer PC to replace my 12 year old desktop. Decided to switch to AMD so had to do a lot of research on which motherboard to select as there are a lot of motherboards out there at a range of prices and with a variety of different features. Chose the Asus TUF Gaming B650 plus wifi as it had good reviews in general and it has a lot of features. It has built in wifi, which was essential for me and this has performed really well. I haven't had any problems with the onboard wifi. The sound quality provided by the motherboard is crisp and clear. Could it be better, yes, but with the speakers I have and at this price you can't get much better. There are plenty of M.2 connections and they all have heat sinks to keep them cool and help them running correctly and not overheating. Also, there are numerous USB 3.2 connections available as well as Type-C so should be suitable for all. All-in-all this is a well built motherboard with a lot of features and is at a reasonable price now that AM5 boards have started dropping in price.

Good quality AM5 matx board
Have been using this for about 3~ months now - Ryzen 7 9700x and 4x24gb Corsair DDR5 6000 RAM. It did have a slight stability issue (no doubt because of the 4 sticks of ram), which was immediately rectified by a BIOS update. Since then it's been totally reliable and performing as I'd expect. The promise of 6 fan headers is slightly misleading in that there are still only 4 PWM signals: 1 of the extra headers is simply full 12v, no control, and the other is a duplicate of the CPU fan header. Nonetheless it's useful to have extra headers and it did save me messing around with a splitter for the CPU cooler. I didn't really want too much RGB and this board doesn't have any built-in which is good. Though it does have headers for both 5v ARGB and 12v RGB lighting should I change my mind. Appearance wise it's smart in black and has plenty of heatsink surface for VRMs. Operation wise the only notable thing for me is that I've heard absolutely no coil-whine type noises from it, no buzzing etc. My previous board (Gigabyte AM4 itx) had a habit of buzzing even when idle. It wasn't too bad but as I keep a near silent PC most of the time it was a touch noticeable - this board is silent.

Good motherboard, not so good software
The motherboard was bought to replace an MSI B650m Mortar wifi that was broken (either it was the BIOS update or faulty memory controller that got it) The Asus TUF Gaming B650 Plus is a good replacement, I particularly like the extra slots of the atx board and the fan curve presets work well - for £165 it is good for the price at the time of purchasing. ***if you are having trouble installing the bluetooth and wireless network drivers, there are 2 different drivers on the Asus site for this board, one for Mediatek and one for Realtek, my board used the Mediatek drivers which was only visible when clicking on ‘see all’ on the page*** As for the add on software ‘Armoury Crate’ and ‘MyAsus’, I have found that these are not needed for my uses and actually used a fair amount of resources to run. The software was easy to use and lets me tweak overclocking settings, fan speed settings, RGB lights and can help with downloading and installing drivers - but I can change the settings from the BIOS (apart from the RGB settings) and you can find the drivers on the motherboard webpage. After uninstalling the both armoury crate and MyAsus, I found in services.msc that there were several Asus services that were still enabled (I suspect these relate to the MyAsus support app) so I disabled them as these were also taking resource, so keep an eye out for these if removing the software. I guess the Armoury crate software could be useful for a beginner in terms of installing drivers, but would suggest not keeping it installed due to the resource usage, and the software terms means they collect lots of data about the system, including games installed, hardware used, overclocking settings, screen resolution etc. which I think is a bit excessive just to change settings that are already available in the bios (not sure about the RGB settings as I didn’t need them) Compared to my old MSI board, the wireless hardware is a bit weaker, previously I was able to use bluetooth headphones with a wireless controller connected via the motherboard, however I was not able to do this with the Asus board and need to use the USB receiver for the controller. Once all the software was removed, the performance is good, the chipset, processor and memory is the same as my old MSI board so this was expected, however it is very nice to have a computer that boots correctly every time and in a few seconds rather than minutes!

Good fast board
Great entry board also ddr4 rgb 5v plus 2x12v led strip lights for under desk behind monitors. Hdmi,vga and dvi sockets. Easy ro install as it comes with a disk. But remember to take of encryption on ssd in your old bios menu. Highly recommend if you don't want to go through the new ddr5 setup.

ASUS PRIME B550M-A WiFi II, una scheda formato MicroATX, ci ho montano un processore AMD Ryzen 5 5500,me l'ha riconosciuto senza problemi, ci ho installato due banchi di memoria SP Silicon Power 16 GB (8 GBx2) XPOWER Turbine Gaming DDR4 3200 MHz (PC4 25600) 288 Pin CL16 1,35 V quindi lavorano in dual channel. Poi sono entrato nel BIOS ed ho attivato la funzione XMP riconoscendomi perfettamente le RAM 3200 MT/s/Timing 16-18-18-36 In dotazione troviamo l'antenna di tipo WiFi 6 (2,4 e 5 GHz) ed oltre i manualetti vari troviamo anche un bellissimo CD (che ormai è sempre più difficile trovarli) con tutti i drivers, questo mi ha permesso di risparmiare molto tempo per prepararlo. In totale ha 4 slot per le RAM due alloggiamenti per schede M.2 e tanto altro. Una scheda affidabile che può tenere dei lunghi carichi di lavoro o gioco. CONCLUSIONI Promosso a pieni voti, vale il prezzo pagato (circa 100€) però peccato che non ha in dotazione base almeno un dissipatore per lo slot M.2

Den bästa moderkortet för detta pris och med många funktioner inbyggda.
