The ASRock B365M Phantom Gaming 4 has a design that uses the three-color combination that is characteristic of the Phantom Gaming product series. The same design is found on other ASRock motherboards, such as the Z390 Phantom Gaming 9 or even the Z390 PG X motherboard. The overall color scheme of the motherboard includes a matte black texture on the PCB and the heatsinks, with subtle dark red accent placed on all surfaces. The dimensions of this motherboard are: 24.4 cm x 24.2 cm.
The B365M Phantom Gaming 4 uses a 10 Phase VRM system which is used in a 6 + 2 configuration. The CPU VRM is split into a 6 + 1 + 1 configuration while the memory benefits from a 2 phase VRM. The MOSFETs used are manufactured by SinoPower and are the models SM4337 for the High Side and the SM4336 for the Low side. The SM4337 MOSFETs are also used on the 2-phase memory VRM.
The capacitors used on this motherboard are manufactured by Nichicon and are the model 12K, part of the Black Caps series. These have been used on plenty of high-end motherboards with very good results across the board.
The power delivery for the CPU is achieved through a single 8-Pin connector found in the standard position, on the upper left corner.
The cooling for the VRM components is done by a single metal heatsink that is mounted on the left side of the CPU socket. This type of VRM cooling has been used before with mixed results, mostly with average cooling. However, these motherboards which use the Intel B365 chipset are only meant to be used with a CPU that has a maximum TDP of 95-watts.
The B365M Phantom Gaming 4 has a total of five (5) 4-pin fan headers that can either be controller through software or the Bios, or can be configured to work as either CPU fan headers, water pump headers or basic fan headers.
The first two fan headers are found on the top edge of the motherboard, one above the CPU socket and the other above the RAM Slots. The next fan header is located in between the VRM heatsink and the top M.2 socket. The last two fan headers are positioned on the lower edge of the motherboard, next to the internal USB headers.
The B365M Phantom Gaming 4 has a maximum RAM capacity of 64GB DDR4, and offers a total of four RAM slots. The DDR4 frequency supported starts at 2133MHz non-ECC and can go as high as 2666MHz. Memory kits that run from the factory above 2666MHz are compatible, but will run at 2666MHz by default. This is a limitation of the B365 chipset.
The motherboard has only a single internal USB 3.0 header, found under the 24 Pin ATX connector, on the right side of the motherboard.
The RGB connectivity is done through a total of three headers, two of these headers are the regular 4-Pin RGB header while the last one is the new 3-Pin addressable RGB header. One of the standard 3-Pin RGB headers is right angled for easier cable management.
The fast storage available on the B365M Phantom Gaming 4 consists of two Ultra M.2 sockets. The top M.2 socket is covered by a metallic heatsink that will provide passive cooling for the installed SSD.
The standard storage available is located in two positions on the motherboard, to aid with the cable management and the overall accessibility of the SATA ports. The main four SATA ports are located on the right side of the motherboard. The last two SATA ports are placed on the lower right corner of the motherboard.
The B365M Phantom Gaming 4 features an additional M.2 socket, also called M.2 E-Key. This socket is dedicated for the installation and usage of a Wi-Fi network card and antennas, the choice of what model of network card, being left to the user.
The motherboard has a total of two PCI Express 3.0 x16 slots and only one PCI Express 3.0 x1 slot. Only the top PCIe 3.0 x16 slot is reinforced with metal, this is often done to add more depth and complexity to the design of the motherboard.
The Bios configuration uses a single 128Mb AMI UEFI bios chip, which has a label that states the installed Bios version from the factory. The bios chip is placed above the two SATA ports and under the chipset heatsink, on the lower right corner of the motherboard.
The system management of the motherboard is achieved by using a single SuperI/O chip manufactured by Nuvoton. The model number of this chip is NCT6791D and it is placed next to the Bios battery, under the main PCIe slot.
The audio system revolves around the Realtek ALC 1200 audio chipset. The filtering is done by five Nichicon made audio capacitors, which are part of the Fine Hold series. The final filtering is done by a line traced around the entire audio system which will prevent any interference.
On the backside, we have the I/O panel.
The I/O panel is as follows (from left to right):
– 1x PS/2 Mouse/Keyboard Port
– 1x HDMI Port
– 1x DisplayPort 1.2
