Hi,

I might be getting a new Windows 10 desktop PC soon and considering the USB ports:

1) How many USB ports should I expect for a computer?

I usually have these devices plugged in to the back USB ports:

  • Mouse
  • Keyboard
  • Printer
  • Joystick (for some games)
  • Speakers (USB powered)

I also temporary plug in these devices to my front USB ports:

  • Flash drive
  • External HDD
  • Camera

2) How many USB 3 vs USB 2 ports should I get?  I understand that only the items above in the second list would really benefit from the extra USB 3 speeds.

3) Do many motherboards still support PS/2, so I could utilise an older PS/2 mouse/keyboard and free up a USB port for something else?

Thanks.

6 USB ports or more will do, dont worry about the amount of USB2 and 3 ports.

Though at the very least you should have 4 USB3 ports, plus the ports on the case (2 to 4)

 

PS/2 is still around on some motherboards, its getting less common but it still remains popular for those who are hardcore about it.

My old Compaq desktop from 2005 has 6 'native' USB 2.0 ports; 4 at the back, and 2 at the front. I've added USB 3.0 functionality via a PCI-e USB 3.0 adapter card (2 ports). I have a Belkin PCI USB 2.0 'add-in' card (4 ports), plus an Advance self-powered 7-port USB 2.0 'hub (which sits on the very front of the tower, at the top, facing forwards).

 

Total? 18 usable ports ( 1 being 'out-of-commission', if you like,'cause it has the USB hub plugged into it).. And most of them get used at some stage.

 

The only things that really benefit from the higher transfer speeds, IMO, are data storage devices; external hard drives, and some flash drives. Cameras, mm; it's debatable, that one.

Thanks for your replies.

 

Why do manufacturers still use USB 2 ports alongside USB 3 ports?  Why not make all ports USB 3 only if USB 3 is the new standard going forward and is backward compatible?

Probably cost-cutting as they probably have plenty of USB 2.0 connectors laying around plus there are still USB 2.0 internal headers to deal with
