PS/2 vs USB keyboards

The motherboard I chose has a PS/2 jack, and I realized that if I get a PS/2 keyboard, it would open up an extra USB port.  It's not like I'd use the PS/2 for anything else, and there are a lot of things you can use via USB.  Are there any other advantages or disadvantages to using the PS/2 for the keyboard?

PS/2

Advantages:

  • Supports full NKRO.
  • PS/2 keyboards aren't polled, but are completely interrupt based.
  • Impossible for it to be delayed by the USB bus being used by other devices.

 

Disadvantages:

  • PS/2 is not natively designed to be hot-swappable, in some situations unplugging and replugging a PS/2 device into the computer will render it unusable until the system is restarted. This is not always the case however, if the system drivers recognize the device then this will not be an issue.
  • PS/2 connectors aren't as durable as some more modern connectors, as such they can be damaged from repeated unplugging/ replugging and suffer from bent or broken pins.

 

 

USB

Advantages:

  • Easily hot-swappable due to the design of USB.
  • Much more popular interface in modern devices than PS/2

 

Disadvantages:

  • Not as compatible with NKRO
  • Sometimes has issues with BIOS or waking up from sleep

The disadvantages of PS/2 is that it cannot be hot swapped and I don't think custom RGB will work.

What is a good PS/2 keyboard that's modern?

For the Best builds and Price lists here is a world where many points of the price have been predefined already for your convenience!

The Xeon E3 1231 V3 IS BETTER Than the Core i5 4690K and a Significantly better value for the non-overclockers or value shoppers.

The OS is like a kind food, Try it before saying if you like it or don't.

I don't think they make many anymore. They are mostly just used for debugging since they always work

If you really wanted a keyboard to plug into your PS/2 slot, there are usb to ps/2 adapters.

 

There's probably some used PS/2 keyboards on Ebay or craigslist too, but they are usually older keyboards that might be a little bit junky. USB is the way to go, unless PS/2 is something that's necessary.

IIRC, Unicomp still makes classic IBM keyboards. Pretty sure you can get them in USB or PS/2 variants.

I still use an old benq keyboard and mouse, and I really like them. I can also play my games fine. The mouse is about 1000 dpi and the keyboard is scissor switch based.

everything works, and I can use my usb ports for stuff that NEEDS usb.

 

I think usb peripherals are actually a bad idea, because it takes up usb ports. Yes, probably ps/2 doesn't support RGB and all of these new features, but why don't they just make a BRANDNEW mouse/keyboard port? A port that DOES support RGB etc.
