Analyzing B450 for AMD Ryzen: A Quick Look at 25+ Motherboards
by Gavin Bonshor on July 31, 2018 8:00 AM ESTASRock B450 Gaming K4
Both the B450 Gaming K4 and B450 Gaming ITX/ac feature similar designs with gunmetal grey heatsinks which feature fins to help direct airflow through the channels, which in turn should help dissipate any excess heat. The boards both feature support for ASRock’s Polychrome RGB technology, with the B450 Gaming K4 having customizable LEDs under the chipset heatsink and additional expansion through a single addressable LED header and standard RGB LED header.
From a quick glance, it looks as though the B450 Gaming K4 has a 9-phase power delivery which appears to be operating in a 6+3 configuration - the Gaming K4 has a heatsink covering the entirety of the MOSFETs, compared to the smaller Gaming-ITX model which only covers the CPU section of the power delivery.
The rear panel of the Fatal1ty B450 Gaming K4 consists of a two USB 3.1 10 Gbps ports (Type-A and Type-C), four USB 3.1 5 Gbps ports, two USB 2.0 ports, an HDMI output, a DisplayPort 1.2 output, a D-sub output and a combo keyboard/mouse PS/2 port. The single LAN port is controlled by a Realtek RTL8111H Gigabit networking chip with the three 3.5mm audio jacks being powered by a Realtek ALC892 audio codec.
The ATX sized B450 Gaming K4 has a host of gaming-themed features, AMD 2-way CrossFire multi-graphics card support (x16 + x4) and integrated RGB. The new ASRock B450 models directly replace the currently available B350 offerings and as it stands currently, the B450 Gaming K4 sits at $99.99.

ASRock B450M Pro4 is not a 6+3 power system but a 3+3. You have to remove the heat sink to see the MOSFET Hi and Lo combos and IC controlersQuarterPunder - Tuesday, March 5, 2019 - link
So if i buy this motherboard do i still need to buy a wifi card/Bluetooth receptor???msroadkill612 - Wednesday, March 20, 2019 - link
"Strix B450-F Gaming ..... Also present is a duo of M.2 slots with both having support for PCIe 3.0 x4 M.2 drives, while the top slot which supports both PCIe and SATA drives up to a size of M.2 2280 (22 x 80 mm), the bottom slot only supports PCIe 3.0 x4 drives with a sizing up to M.2 22110 (22 x 110 mm)."ALARMINGLY WRONG!
Newegg:
"AMD Ryzen 2nd Generation / Ryzen 1st Generation Processors: *
1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x4 mode)**
1 x M.2 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (PCIE 3.0 x4 mode)***"

edit - to remove any doubt - in full, the specs are:"AMD Ryzen 2nd Generation / Ryzen 1st Generation Processors: *
1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x4 mode)**
1 x M.2 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (PCIE 3.0 x4 mode)***
AMD Ryzen with Radeon Vega Graphics Processor: *
1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (SATA & PCIE 3.0 x4 mode)**
* Support StoreMI and NVMe RAID.
** When the M.2_1 Socket 3 is operating in SATA or PCIE mode, SATA6G_5/6 ports will be disabled.
*** When the M.2_2 is occupied by M.2 device, PCIe x16_1 will run at x8 mode."

I run windows from external SSD so I need fast USB ports for it to run smooth. Can I replace the USB ports by 3.2 gen2 when needed?g0rnex - Sunday, June 23, 2019 - link
I run win10 from an external SSD. for that I need a fast USB connection for windows to run smooth.Would it be possible to change the USB ports in the future? OR even now already by a 3.2 gen2. Or wouldn't replacing the ports speed up my connection with the external SSD?
Also I would like a good bluetooth connection. Do I need to use an adapter?
looking into making this build:
