Power outage damaged computer?

[Carter fields]

Since last night when I had a power outage where the power went out for a few seconds but came back on. I have a new PC it's like my forth build and if it is of imporance the outage was not lightning caused (I heard those are very bad) anyways I left it running all day to make sure it was fine, my wifi adapter did have an issue after shortly it stopped working (but it's probably just a software issue) I plugged in my back up and it worked great. I would also like to note that this is like the second power outage in the same week, the first one I came home and oddly my PC was still at the counterstrike menu, I ran 3D mark firestrike and it scored 50 less than 7680 (basically nothing since I get different scores every time But in similar ranges. My computer ran all day without issue , my SSD seems to be fine as well and everything seems normal, also idk if this is worth mentioning but my PSU is an ANTEC 550VP 80 Plus , not the best but I've heard great things about antec and it's 80 plus so. Lastly my motherboard said Asus anti surge protection was triggered because the psu was unstable , (this was during the second outage) .
please just someone help calm my mind I have like OCD so I can't stop thinking about the what ifs,
Lastly I'm getting an APC UPS surge protector for 50$ at frys tomorrow

if the power drops off to 0v. most time you end end with a damaged windows file or two...real bad is hard drive crash if the read/write heads were moving. brown outs or zpikes can burn out parts. most time good power supply will take the hit.

real bad is hard drive crash if the read/write heads were moving.

HDDs don't magically crash from losing power even during active IO. The heads have recall springs to automatically park them on power loss much faster than the spindle can lose speed and cause heads to land. If you had a HDD crash from "losing power", there must be more to the story that you either aren't telling or aren't aware of.

As for OP, if everything works, don't lose sleep over it. As long as you have a good quality power supply that doesn't freak out when power gets cut, the component most likely to fry itself is the PSU and only the PSU. A crappy power supply may go unstable after receiving unusually unclean power and the garbage power it may put out to your components may fry them. In the case of exceptionally crappy PSUs like Diablotek's, the PSU may decide to fry your components for no apparent reason.
