Board Layout

Keeping with that camouflage theme that the box has going for it, the B650E Steel Legend WiFi heatsinks and PCB uses this same pattern. The motherboard has three distinct color variations; one being the gunmetal gray for the heatsinks, white for the Rear IO and of course the overall camouflage pattern found throughout. The back of the motherboard is as basic as it gets. There is no backplate for extra PCB strength to prevent flexing with heavier graphics cards, which can double as a hazard guard from accidental damage.


AMD's changes to the socket also comes with some compatibility challenges as well. Many brands currently selling AM4 CPU coolers already have forwards compatibility, but not all will work. What changed is the backplate, which was previously removable for the AM4 (PGA) socket, and is now an integral part of this new AM5 (LGA) socket. This means any cooler that has its own backplate as part of the installation will be incompatible, unless a an adapter is available from the manufacturer.

ASRock provides an ample amount of space for a majority of the AIO coolers on the market. Air coolers like AMD Wraith Prism will not have any problems, but larger ones may and conflict depending on the orientation. The ASRock B650E Steel Legend WiFi has four potential conflict zones, with the obvious being the two VRM sections to the top and left of the AMD CPU socket. Below is the M.2 heatsink and to the right is the DIMM slots. This means the air cooler in question needs to be compact enough to fit in the space allotted space or tall enough to avoid collision with the surrounding heatsinks and system memory.

Note: AMD recommends 240-280 mm AIO (or better) for the Ryzen R9 7950X/7900X to keep the turbo frequency on target. Thermal observations from using the AMD Ryzen 7950X during this review place the CPU at 95°C, which is perfectly normal. The AIO solution isn't a requirement if heavy multi-threaded application performance is a priority, though it will provide the highest boost clocks overall. Undervolting and using PBO is also an option, to circumvent CPU cooler thermal limitations.

The ASRock B650E Steel Legend WiFi has two PCIe slots, with the first being Gen 5 x16 and reinforced for extra stress support. The second PCIe slot is physically x16 as well, but internally wired for x4 and will only operate in PCIe x4 Gen 3 mode regardless of the AMD processor or amount of M.2 sockets populated.


After removing the heatsink, we can get a closer look at the B650E chipsets (PCH).


Above the PCIE x16 Gen 5 slot (top) is a single M.2 Gen 5 x4 compliant socket connected directly to the CPU. Below the bottom PCIe slot is two Gen 4 x4 M.2 sockets which are routed through the B650 chipset. These all have heatsinks that provide passive cooling.


The ASRock B650E Steel Legend WiFi includes startup LEDs for easier troubleshooting. Considering that the AM5 socket is new to everyone, it is always good to get a readout of what stage the boot process is on, or what it may be stuck on. However, due to the long boot sequence, the DRAM light will blink while training, which happens to the same when the memory does not work. This can make troubleshooting a bit of a challenge for memory overclocking.


As requested by some readers, here is a close up of the Wi-Fi 6E card used. This one is by Mediatek (MT7921K).


The ASRock B650E Steel Legend WiFi uses a two 8-Pin EPS connector for higher power management.


The motherboard has four RGB headers for fans, coolers and whatever else needs the RGB treatment. Next to the onboard audio section is a a single 12 V (4-pins) and one ARGB 5 V (3-pins). In the top right of the motherboard are two more ARGB 5 V (3-pins) headers.

One of the major differences you'll notice between the X670 and B650 chipset is the amount of internal USB headers and external high-speed connections. This is because the B650 only has one chipset, with less overall PCIe lanes available to be allocated towards SATA ports, USB and PCIe slots. Of course motherboard vendors can rework the allocation to a certain degree and we can see here that the B650E Steel Legend WiFi has done just that. Two USB 3.1 Gen 1 (5 Gbps), two USB 2.0 and a single USB-C (20 Gbps) headers can be found internally.


The B650E chipset can supply up to four 6 Gb/s SATA ports natively. ASRock has taken away two of these and used the bandwidth elsewhere, leaving just the two SATA ports.


ASRock has used the Realtek ALC897 Audio Codec for its on-board audio solution which supports 7.1 HD Audio with Nahimic Audio software. This 7.1 setup configuration requires the use of the Front Panel audio jacks on the case. Without doing so, the audio output is limited to two channels from the Rear IO outputs.


An up close inspection of the Rear IO panel, reveals a good balance for this product tier. Since all Ryzen 7000 (X) CPUs (currently) support onboard graphics, ASRock included HDMI and DisplayPort for video output. Next to those is the WiFi 6E and BIOS Flashback button. This button allows the motherboard BIOS to be flashed without a processor present. This feature is built into the AM5 platform, so there's no reason for manufacturers not to take advantage of it. Moving along, ASRock has a number of USB ports are well. First is two USB 2.0, four USB 3.2 5 Gbps (Blue) ports and the final two are USB 3.2 10 Gbps (Teal / USB-C).
