PS/2 or USB keyboard

Just concern which would be better to use between PS/2 and USB. Lot of these people on the internet mention/prefers PS/2 over USB because of response time in only 2ms. USB known as delay, lag input that sends to the computer (CPU), is that true? Just interesting topic/discussion about them.
The truth is that should I use the good ol’ day PS/2 port for keyboard? I got adapter where I can put USB Keyboard into that and plug into PS/2 port.
Your thoughts/opinions on this please?
Answer #1
The input delay is unnoticeable but the advantage over USB is that PS2 has ‘N-key rollover’ which means an unlimited number of keys can be pressed at the same time. To be perfectly honest, most expensive USB keyboards nowadays can do at least 6 keys at once (mine can do 12). Just ask yourself if you’ll really be pressing 101 keys at once. At least 6 is fine imo for gaming.
Answer #2
Its more realistic to look at mechanical keyboards and such.
Maybe the PS/2 connector will be phased out eventually, USB does in fact pull slightly more CPU resources.
But our hardware is so decent these days, its not really that of a big deal.
USB tends to be good, you can plug it in anytime.

Yeah that exactly true and the point. I was looking at mechanical keyboards awhile ago and found they offered gold plated usb. Was thinking of getting Steelseries 7g…
I have razer keyboard at the moment but not really that great. It’s Razer Lycosa Mirror
Answer #4
The gold plated USB is purely gimmick.
Silver has the best electrical conduction.
I was thinking of Getting a 6G V2, Cherry Black’s must be fully depressed which is good for FPS games.
I currently have a old G15 V2, its LCD was good for email notifications, temp displays and BFBC2 stats.
But its a pain to clean.

I somewhere read once that if you use USB Keyboard/mouse simultaneously with a USB pen drive or external hard disk, then they share the bandwidth and the speeds of pen drive or external HDD can fall by a few megs per second(?)
I don’t know if this is true, but I started using PS2 since then, as they cost the same.
Answer #6
Silver has the best electrical conduction. Gold is there to reduce EMF noise not increase the conductivity.
Browns and reds are the best for gaming imo but it’s kinda subjective. I know guys who game better than me on MX blues vs me on whites.
I have razer keyboard at the moment but not really that great. It's Razer Lycosa Mirror Pretty much all Razer keyboards suck except the BlackWidow. The BW has great build quality and for the price it includes a ton of features.

I’d rather use a choke at the end of the wire, its a sure bet.

Gold does not reduce EMF noise.
Gold does not oxidize and corrode the way other metals do so it makes a solid electrical connection for much longer.
Unless both the plug and socket are gold plated, it is only half helpful.

Yeah, pity just don’t like arguing anymore, its kind of tiring just posting.
You get “gold plated cables”, sadly they just don’t seem to be much of a difference to your average cable.
It will be silly enough to suggest gold to suppress EMF when you actually need specially designed filters.
Its just like saying DC motors are better than AC motors, when they aren’t.

Yes, if you look inside a USB connector, or any other connector for that matter, most of them you will find are gold plated to insure good contact and reliability..
Always handy to have a PS/2 keyboard around in case you are working on a PC and you want to get into bios but can’t because USB has not been enabled
Answer #12
PS/2 has better response times, but it’s not really noticeable performing regular tasks.
I think the key issue here is hardware compatibility, as quite a lot of new machines don’t support PS/2.
