HELP strange problem. PSU ?

[BathSaltZombie]

hey guys ive been experiencing some weird shit with my new pc.

the other day i was playing dota2 and my keyboard starting cutting out, then it wouldnt work at all, LEDS kept fading on and off and eventually i couldnt type at all. soon after it quit i then experienced a massive crash. i turned off the pc, made sure all my cables were seated correctly, powered back on again, went to login screen. i tried typing in my password, it maxed out characters in text field then pc shut off again. i waited awhile turned pc back on with no problem, logged in, ran antivirus scans, everything seemed to be fine. after this i played for almost two days with no problem then today while playing i ran into keyboard problem again. i tried dif keyboard and it didnt work either, my mouse works but no keyboard, and no crash this time. i dont think peripherals are the problem here, ive noticed a faint buzzing sort of noise and im 95% sure its my psu. i have a modular corsair CX600M psu. its 600 watts. this psu is supposed to be silent. 

do you guys think my PSU is the problem here? 

-i5 4690k cpu
-GTX 960 gpu
-8GB 1866mhz vengeance ram
-Gigabyte mATX z97mx mobo 
-256gig SSD 

im not overclocking or anything, just playing dota2. Ive only had this pc built for about a week. ive had hours of gameplay with no problem but ive ran into this keyboard problem twice now, first occurrence a massive crash was included. what do you guys think ?

Have you try updating your keyboard drivers and change what port you keyboard is plugged into

There is your problem, you are using a Corsair PSU. Haha, just kidding.

This could be a NUMBER of things, unplug all USB devices besides the mouse and keyboard but plug them into different USB ports. This CAN happen if something is shorting out such as a USB device although most modern motherboards have protection against this. I would suggest purchasing a new EVGA PSU and trying it out for a while, if this is still happening, return it and look at other options.

yeah i've tried all USB ports. my mouse works fine, so hopefully its just my keyboard.  But i did have a couple big crashes the other day and i can hear a slight buzzing from the PSU so it could be that too.
