PS2 port is required by motherboards because their products have to be interoperable with more seasoned condiments. PS2 ports also allow for faster enrollment because they directly block the processor.
Moreover, when entering the BIOS or navigating the Windows installer, the PS2 Port is a surefire way to ensure you have control over the system.
Many motherboards still have these ports, which are labeled with a color code and even icons, i-e, purple for the keypad, and green for the mouse. Because of this, modern motherboards and higher-end motherboards no longer include them.
PS2 pairing ports suitable with both peripherals can be found in many cases. Adapters from PS2 to USB and conversely are, however, readily available. The detailed of the reasons for PS2 port in motherboards have discussed below:
- Because most gadgets haven’t been updated, there’s a chance that someone will try to connect them to this Port. As a result, they require their products to be compatible with more seasoned ingredients.
- PS2 ports allow faster enrollment because they block the processor more directly than USB ports. These ports have a multi-key acknowledgment feature, which is essential for some clients who need to enroll multiple keys simultaneously.
What Are PS2 Ports Used For?
Ps2 is widely used for keyboard and mouse connection with the computer.
In some of the cases, they are also preferred for security purposes, but their principal use is to connect computer devices by USB. The further details of the uses are described below:
- The PS2 Port is a 6-pin mini-DIN connector connecting keyboards and mice to a PC.
- PS2 adapters have almost entirely been replaced as the principal means of connecting computer devices by USB connectors.
- In some scenarios where security is critical, the PS2 may be preferable.
- Difficulties with USB drivers may inhibit the keyboard from conversing with the utility, which isn’t usually an issue with PS2.
- If there aren’t enough USB ports, PS2 could be used instead. PS2 keyboards and mice can be used to clear USB ports for other handsets such as external hard drives.
Pros & Cons Of PS2 Ports
The basic Pros of the PS2 Port is its unique and appealing console, along with no restriction on the vital roller.
Moreover, PS2 ports are identical to a 5-pin DIN connector that can be utilized with a simple wiring connection.
There are Cons of PS2 ports, which include long loading times and only two controller ports. Along with all this, they are also no means to swap, and due to a centralized micro-controller, they may have a cheap design.
The detailed discussion about the advantages and disadvantages of PS2 ports are as follows:
- A large number of games means that there is something for everyone.
- The design of the console is unique and appealing.
- Games are easy to come by and are inexpensive.
- The PS2 interface has no restrictions on key rollover, and neither do USB keyboards unless they are used in BOOT mode.
- The PS2 keyboard functionality is electrically identical to the 5-pin DIN connector used on earlier AT keyboards, so keyboards intended for one can be used with a simple wiring connector to connect to the other.
- Long loading times are expected.
- There are only two controller ports.
- You may need a lot of memory cards.
- They’re not meant to be swapped out quickly. PS2 ports are used to connect the digital I/O lines of the external device’s microcontroller to the digital lines of the motherboard’s microcontroller.
- They can only be inserted in one direction and should be adequately rotated before connecting. PS2 adapters are not intended to be wired in and out frequently, which can cause pins to bend or break.
- Both PS2 ports are generally controlled by a centralized microcontroller on the motherboard in a standard implementation. This renders design and production extremely simple and inexpensive.
Why Is PS2 Better Than USB?
USB is better than PS2 because USB is a far better and more popular interface than PS2.
External hard drives, joysticks, microphones, flash drives, and cameras are connected using the USB standard.
PS2 is not intended to be a hot plug; you should not lift it out and the plugin and expect it to work.
The default setting is that the computer will not work until the PS2 connector is plugged in and the computer is restarted.
The way a device connects to a computer is the distinction between a PS2 and a USB. Although USB has replaced PS2 as the modern peripheral device interaction standard, the PS2 standard is far from dead.
Mice with both connection standards typically include a converter to allow them to work with the other. The USB ports have the following advantages over PS2 ports:
- The USB port is designed to give you more options. Attach it and overlook it with PS2 devices. PS2 devices’ pins have a proclivity for bending, giving USB ports a benefit.
- USB is a standardized I/O interface. It’s also highly compatible. Having said that, USB keyboards come in a variety of styles.
- There are no issues with swapping USB keyboards and mice. Simply plug them in and out several times. You won’t have any problems.
- USB keyboards are compatible with a wide range of devices, including laptops, computers, and smartphones. As a result, they have a positive aspect of compatibility.
Keyboards and mice for both USB and PS2 are excellent. However, if you want to use a single combination for multiple systems, USB combos are the way to go.

If you don’t have any special requirements and aren’t using an old system or OS, USB is the way to go. It will provide you with additional benefits. If a few Nanoseconds of latency isn’t important to you, USBs have more advantages.
Do They Still Sell Motherboards With PS2 Ports?
Yes, PS2 ports are still occasionally found on all IBM compatible motherboards. But, in today’s computers, mostly the keyboard and mouse are connected via USB.
Moreover, the PS2 system is now deemed a legacy port; it is still available on some motherboards for security and space reasons.
Can You Damage A Motherboard By Hot-Swapping A PS2 Mouse Or Keyboard?
Yes! There must be some voltage + and – present. On PS2 ports, there is a fuse. Both the motherboard and the handset you’re unplugging, such as the keyboard and mouse, are at risk and can be damaged by hot-swapping.
There’s a chance it’ll work out, but you’re more likely to fry them. Unless your computer is on USB, it is recommended that you turn it off. Perhaps you should try it with the VGA, hard drive, and sound card to see if it works.
Moreover, PS2 ports aren’t designed to be swapped out quickly. They’re made to connect the microcontroller digital I/O lines in the external device to the microcontroller’s digital lines on the motherboard.
The handsets must be comparable enough the driver trying to run on the target host recognizes and can use the new device whether they are hot-swapped. The device will not work correctly if this is not done.
Gaming is the most common reason for PS2 ports in motherboards. The PS2 mouse keypad is active from the start and can be used right away, with arguably faster/better response times than USB and the ability to hold off several keys at once and have them all sign up correctly.
Furthermore, the PS2 connection penetrates the PC’s bowels and core more deeply than the USB connector. Hopefully, this article will clear up any misunderstandings about PS2 ports.
