ASRock B550 PG Velocita Review & Specifications – 2020

ASRock B550 PG Velocita ReviewOur list of ATX AMD B550 motherboard reviews is expanded with this new ASRock B550 PG Velocita review, now a more versatile version presented by the manufacturer for this mid-range chipset.

It is provided with 4 PCIe slots with Multi-GPU capability and a double M.2 slot supporting PCIe 4.0 in one of them. It also has an M.2 E-Key slot for Wi-Fi 6 (not included) and a high-end sound card. All this is completed with 14 phases of 50A DrMOS to support the Ryzen 3000 CPUs and their overclocking.

In the first instance, we have a flexible cardboard box that serves as the first wrapper, which lets us see the large “Phanton Gaming” logo on its main face. This is accompanied by a lot of information about the support, platform, and a description of components on the backside that uses photographs of various parts.

The bundle is made up of the following elements:

  • Motherboard ASRock B550 PG Velocita
  • 4x 6 Gbps SATA Cables
  • 3x screws for SSD and Wi-Fi installation
  • 2x support extensions for M.2 SSDs
  • Manual
  • Support DVD
  • Cable and indicator stickers
  • Two velcro straps to hold cables

Not having an integrated Wi-Fi card, the possible antenna has been omitted, something that is perfectly understandable. Otherwise, we do have everything expected, including some decorative stickers and the DVD with drivers.

ASRock B550 PG Velocita Review – Mid-Range Motherboard

Design and Features

The ASRock B550 PG Velocita boasts a wealth of aesthetic detail in a standard ATX design with a size of 305 × 244mm. On the background in matte dark grey, we have serigraphy that combines the distinctive white and red color of the Phantom series, which in turn merges with the lines of the heatsinks. In the back areano type of protection or metal casing has been provided, and we only have the antistatic coating for the electric tracks.

This time we have two lighting zones located on the rear I / O panel protector and above the chipset heatsink. It has Polychrome Sync technology and can be managed from the board software. Additionally, the four headers for lighting strips, two of them with 3-pin 5VDG for addressable strips, and another two 12VGRB for RGB strips.

Standing in the upper area, we find a large aluminum double heatsink that is responsible for cooling the two areas of the power supply phases. To increase effectiveness, we have a copper heat pipe that joins both blocks and conductive silicone thermal pads that improve heat transfer.

We go down to the bottom half of the board, and we see that the B550 chipset has been covered with a passive aluminum heatsink which in turn is under an aluminum and plastic casing that liven up the design of the area. 

Although we may not see it, here is a “PG” logo that lights up. But the most exciting thing in the area is the two passive aluminum heatsinks that have been installed in the M.2 slots. In the present scenario, these types of heatsinks are essential, since high-performance SSDs generate enough heat, and much more if they are PCIe 4.0 like the ones that this board supports.

As for details of connectivity and internal accessibility, we have a good number, with a total of 7 4-pin headers for fans and support for water pumps of liquid cooling systems. To this are added a pair of internal buttons to start and restart the board and a debug LED panel to notify the BIOS status codes. This time we have no buttons on the I / O panel for Clear CMOS and BIOS update, and we only use the internal jumper.

VRM And Power Phases

After seeing the main and aesthetic characteristics, it is time to focus on the components. And the first will be the power configuration, which consists of 14 phases in total divided into 12 for Vcore and 2 for SoC

For the current input, we have two headers, one of them with 8 pins with a steel coating, and the other with 4 pins. Both have a high-density solid pin that reduces energy loss by 23% and reduces the temperature. The ATX connector also has these types of pins, but without steel reinforcement. Added to this is a double layer of 2-ounce thick copper tracks that improve the energy delivery to the phases.

In the first stage, we have 12 50A capacity DC-DC SIC654 converters for the Vcore and another 2 SIC632A for the SoC. These DrMOS MOSFETS are of good quality and should be prepared for high-power processors and more than 8 cores. In the next two stages of signal smoothing, we have 14 premium solid chokes with 60A capacity and Nichicon Back Caps 12K capacitors that last over 12,000 hours.

We still have an important element, the controller or EPU, which this time is an AA229004 to manage all the power phases. It is important to know that these 14 phases have signal doublers, being installed on the back of the board. So they will not be real phases as such, since their management will be in sets of two elements.

Socket, Chipset And RAM Memory Support

We will now see in more detail about the elements that define the platform to which this ASRock B550 PG Velocita board belongs, as well as the RAM support.

The socket is, as usual, the AMD PGA AM4, and it will continue at least until next year. It ensures compatibility with AMD Ryzen 3000 Zen 2, AMD Ryzen 4000 Zen 3 and AMD Ryzen 4000 Zen 2 APUs with Radeon integrated graphics. But as with the rest of the boards on the platform, it will not support Zen and Zen + processorsincluding APUs belonging to these generations. So do not buy a board as a mere update if you have any of these processors. At least it does ensure compatibility with Zen 3 and the new Ryzen 3000XT CPUs.

The chipset that gives life to the Southbridge of the plate is the AMD B550, having made a significant update for the previous B450. This version has a total of 8 PCIe 3.0 instead of 2.0 and allows us to use the 20 PCIe 4.0 lanes available in the AMD Ryzen 3000 Zen 2 processors without problem or limitation.

The communication interface between the Chipset and the CPU does change, going from having 4 PCIe 3.0 lanes to 4 GB / s instead of 4.0 as in the X570. We must add about the support for 6 or 8 SATA ports depending on the lanes that are taken from the chipset, and connections for peripherals with a maximum of 4 USB 3.2 Gen2 ports, or the equivalent in USB 3.2 Gen1 or USB 2.0. Remember also that Ryzen 3000 CPUs natively support up to 4 USB 3.2 Gen2.

The RAM capacity goes up to 128 GB through 4 DDR4 DIMM slots with Dual Channel support. For all the CPUs that we install, a maximum frequency of 4733 MHz will be supported thanks to the support for OC XMP 2.0 profiles. You already know that from the BIOS, you can activate and manage the characteristics of these profiles if the board does not automatically detect it.

Storage And PCIe Slots

Let’s review the internal expansion slot capacity of the ASRock B550 PG Velocita mobo. The distribution of storage capacity results in two M.2 PCIe x4 slots, one of which will support PCIe 4.0 and the other PCIe 3.0. In both cases, we have passive heatsinks with conductive silicone thermal pads to ensure good temperatures and durability of SSD drives. And next to them, the 6 SATA III, 6 Gbps ports, located in a lower right panel. Let’s see the particular characteristics of each M.2 slot:

Slot M.2_1 is directly connected to 4 PCIe lanes of the CPU. This supports formats up to 2280 or only PCIe SSDs.

The M.2_2 slot is found under the B550 chipset block. It does support PCIe and SATA SSDs, as well as sizes up to 22110.

So we can easily install one of the high-performance PCI 4.0 SSDs that are available on the market. Being two slots, these will support RAID 0 and 1, while the SATA ports will support RAID 0, 1 and 10 from BIOS. Support for AMD StoreMi 2.0 will be added in the final stretch of the year. They will also offer support for the ASRock U.2 Kit.

Now we continue with the configuration of expansion slots, of which we find 2 PCIe 3.0 in full x16 format and another two PCIe x1. 

Network Connectivity And Sound Card

We continue inside the PCB to see now what is the network capacity of this B550 PG Velocita and its sound card, and we anticipate that it is not bad.

The first question is easily answered since we have a Realtek RTL8125B Ethernet LAN chip that offers a good bandwidth of 2.5 Gbps. This is one of the most used together with the Intel I225 of the same capacity, and they are the definitive steps to the standardization of 2.5 G in wired connections for new generation boards.

Although it is true that on this board we do not find a Wi-Fi card, we do have an M.2 E-Key slot with the clear Wi-Fi distinctive between the PCIe1 and PCIe2. Besides, the rear backplate has two openings to install the extension headers for the external antenna, which is also not included.

The second main element will be the sound card, which in this case is the high-end codec Realtek ALC1220. This supports up to 8 stereo audio outputs or in configurations up to 7.1 surround thanks to the 5 rear Jack outputs and an optic.

It offers a maximum sensitivity of 120 dB SNR in stereo output with support for 32 bit / 192 kHz audio and DAC with a differential amplifier. Also included are Japanese capacitors and a NE5532 Premium headphone op-amp that supports up to 600 ohms impedance. All this can be managed using Nahimic 3 technology and the corresponding software.

Rear Ports And Internal Connections

We are approaching the final stretch of the component analysis of the ASRock B550 PG Velocita without losing sight of the connectivity for peripherals.

In terms of USB ports, we have a total of 8, of which 2 of them work at 5 Gbps and another 2 at 10 Gbps. It is not an extraordinary capacity, but at least we have the eight that we usually order in these new plates. An HDMI 2.1 video port has not been missing in case we want to install a new generation APU with support for 4K @ 60 Hz resolutions.

We note the absence of the Clear CMOS button on this rear panel, which should be present as a Phantom Gaming, but we will have to resort to the internal jumper.

We have already seen at the beginning that ASRock has had the detail of including buttons for power on and restart. We as the gamers are quite satisfied with the variety of internal connectivity since we could incorporate up to 7 USB ports of which one of them is 3.2 Gen2 Type-C, which many high-end chassis already include.


As for the BIOS of this board, it is presented with a single 256 MB CMOS with an interface practically the same as the rest of the higher-range Phantom Gaming boards and other chipsets such as the X570. If there is something that almost always characterizes the ASRock BIOS, it is the simplified interface and how little it costs to detect new components, such as this CPU or RAM.

This version has support for updating using Instant Flash, as a usual method from USB memory. RAID system configuration is added very easily with the integrated tool and secure-erase functions for SSD. It may be time to introduce an advanced tool to manage onboard fans, Fan Xpert style and more.

And being a chipset with overclocking support, we will have at our disposal the advanced management of offset voltages and VRM performance, and the possibility of storing them in up to 10 quick access profiles. It is a very good BIOS, stable and with guarantees for the user, and in this regard, we have nothing to object to.

Temperatures And Overclocking

Finally, it’s time to check how the VRM has performed with duplicators of this board by overclocking the AMD Ryzen 9 3900X CPU. This time we have set it to 4.4 GHz in all the cores in a stable way at 1.33V and activating the 4000 MHz XMP profile of the RAM.

On this occasion, we have not been able to check the internal temperatures of the VRM because it could not be monitored from the software. However, we see a good surface temperature around 60ºC maximum and 50ºC in stock. Besides, the tested processor is the second most powerful of the generation.

We are finalizing this review with our conclusions about this ASRock board. After thoroughly reviewing it, we can confidently declare this board as one of the most attractive high-end board within the category to which the B550 chipset belongs.

If what we are looking for is aesthetics, ASRock gives us an unbeatable appearance in pure Phantom Gaming style. Along with screen printing, it has two RGB lighting zones and a large part of the key areas covered, for example, the EMI protector, sound card or Chipset, although it has plastic elements in all three places. It also has 4 RGB headers and power buttons and on-board reset.

For cooling, a good amount of aluminum has been used in the double block of the VRM and the two M.2 slots. They are elements that generate enough heat, and it is always good to have certain guarantees on a board like this that PCIe 4.0 SSDs are supported in one of the M.2 slots.

The connectivity is at a very good level in all the sections. Its 4 PCIe slots do not share a bus with anyone. It is a good thing to fit the possibilities of the platform. The two M.2 slots and 6 SATA ports with RAID support are also not missing as usual. The minimum requirements of 8 USB ports and expansion capacity up to 7 more are met, with an internal USB-C header. The network section offers a 2.5 G LAN link and the possibility of mounting Wi-Fi 6, something to consider.

The stability with high-performance processors like this Ryzen 9 3900X has been remarkable, even allowing overclocking with good stability. We have a complete BIOS and easy to use, although it is true that for these types of processors an X570 is always better.

Finally, the price of the ASRock B550 PG Velocita will be around 220 dollars or less. At this point, it should no longer surprise us, since the platform was born with somewhat high prices.
