So one night i was playing some games with my friends when all of a sudden my PC turned off, I went to check if it was still plugged in because I thought I might have kicked the plug, but it was still plugged in, I then heard some zapping coming from the PSU and then a pop like something just exploded, which i guess something did because the PSU started smoking.

I plugged in another PSU that I borrowed from a friend and all that happened is the PSU fan would spin for half a second then stop.

I was wondering if anyone knew the chance that this could have killed other components in the computer?

PC Specs:
i5-4670k haswell quad-core CPU
Asus Z87-a Mobo
Msi gtx 970 100 ME GPU
Corsair vengence pro 8gb ram
samsung 840 evo 250 gb ssd
2 WD 1tb blue hdd
corsair cx750m PSU
windows 10

Generally the better quality PSUs have built in circuitry protection to keep from blowing system components (a circuit firewall if you will meaning the PSU will "take one for the team"). The older Corsair CX line (those made prior to say starting a year ago) were junk with minimal protection. So it's possible it did ruin your components. Here's Tom's PSU Tier list. Note the CX series is listed as Tier 4 (second from lowest quality). The newer CX line has been upgraded to a Tier 3.

The EVGA SuperNova GS series is a top-tier PSU and should work. So if it's not, then you may have something like blown capacitors on your motherboard. They will look like a corroded battery on...
