Size (HxW)

Motherboard dimensions in height and width. It is assumed that the traditional placement of motherboards is vertical, so in this case one of the dimensions is called not the length, but the height.

Motherboard sizes are largely determined by their form factors (see above), however, the size of a particular motherboard may differ slightly from the standard adopted for this form factor. In addition, it is usually easier to clarify the dimensions according to the characteristics of a particular motherboard than to look for or remember general information on the form factor. Therefore, size data can be given even for models that fully comply with the standard.

The third dimension — thickness — is considered less important for a number of reasons, so it is often omitted.

USB 2.0

The number of USB 2.0 connectors provided on the motherboard.

USB connectors (all versions) are used to connect to the "motherboard" USB ports located on the front panel of the case. With a special cable, such a port is connected to the connector, while one connector, usually, works with only one port. In other words, the number of connectors on the motherboard corresponds to the maximum number of front USB connectors that can be used with it.

Specifically, USB 2.0 is the oldest version widely used nowadays. It provides data transfer rates up to 480 Mbps, is considered obsolete and is gradually being replaced by more advanced standards, primarily USB 3.2 gen1 (formerly USB 3.0). Nevertheless, a lot of peripherals are still being produced under the USB 2.0 connector: the capabilities of this interface are quite enough for most devices that do not require a high connection speed.

HDMI output

The motherboard has its own HDMI output.

Such an output is intended for transmitting video from an integrated graphics card (see above) or a processor with integrated graphics (we emphasize that it is impossible to output a signal from a discrete graphics card through the motherboard chipset). As for HDMI specifically, it is a combined digital video/audio interface specifically designed to work with HD resolutions and multi-channel audio. Today it is the most common of these interfaces, HDMI support is almost mandatory for video devices that are compatible with HD standards.

The specific capabilities of HDMI vary by version (see below for more details), but in general they are quite impressive — even in the earliest (current today) HDMI v.1.4, the maximum resolution is 4K, and in newer standards it reaches 10K. So in motherboards, the quality of the video transmitted through such an output is often limited not by the interface capabilities, but by the graphics performance of the system.

USB 2.0

The number of USB 2.0 connectors installed on the back of the motherboard.

Recall that USB is the most popular modern connector for connecting various external peripherals — from keyboards and mice to specialized equipment. And USB 2.0 is the oldest version of this interface that is relevant today; it is noticeably inferior to the newer USB 3.2 both in terms of speed (up to 480 Mbps), and in terms of power supply and additional functionality. On the other hand, even such characteristics are often enough for undemanding peripherals (like the same keyboards / mice); and devices of newer versions can be connected to the connectors of this standard — there would be enough power supply. So this version of USB is still found in modern motherboards, although there are fewer and fewer new models with USB 2.0 connectors.

Note that in addition to the connectors on the rear panel, connectors on the board itself (more precisely, ports on the PC case connected to such connectors) can also provide a USB connection. See below for more on this.

PS/2

The number of PS/2 ports provided in the design of the motherboard.

PS/2 is a dedicated port designed to connect exclusively to keyboards and/or mice. The traditional motherboard configuration for a PC provides 2 such ports — for the keyboard (usually highlighted in lilac) and for the mouse (green). However, there are boards with one connector, to which you can connect any of these types of peripherals, to choose from. Anyway, the presence of PS/2 can save the user from having to occupy USB ports for the keyboard / mouse; this is especially useful if you have to deal with a lot of other USB peripherals. On the other hand, for a number of reasons, this connector is considered obsolete and is used less and less; and PS/2 peripherals are produced mainly in the form of USB devices, additionally equipped with PS/2 adapters.

CPU power

The type of connector for powering the processor installed on the motherboard.

Most modern boards use a 4-pin connector, and most power supplies in ATX cases are also designed for it. In addition, there are other types of power connectors, they all have an even number of pins — 2, 6 or 8. Two-pin power is used mainly in motherboards of miniature form factors like thin mini-ITX, designed for low-power processors. 8-pin connectors, on the contrary, are designed to power the most powerful modern processors. It is believed that such a connector provides a more stable power supply and more precise tuning of its parameters. But connectors for 6 pins are not found separately, they usually complement 8-pin connectors in high-performance motherboards, in particular, gaming ones.

Also note that some boards have 2 or even 3 power connectors — most often in the format 8 + 4, 8 + 8 and 8 + 8 + 6 pins. This functionality is designed for high-end CPUs with high power and power consumption, for which one connector is not enough. There is another specific option — “motherboards” without a separate processor power supply : these are models equipped with an integrated CPU, which receives energy through its own board circuits without a sp...ecial power connector.
