So, I start up my PC. It runs very well. My basic parts include an asus z87 mobo, an Intel i5 4670k, asus gtx 770, and a 750w bronze Corsair psu. It is the PSu that seems to be the problem. Every so often, after ive been using it (not necessarily playing games) for an x amount of time, it shuts down. Upon reboot, I'm greeted with : Power surges were detected on start up, ASUs anti-surge was triggered to prevent damage from a faulty power supply. So, I assume that its something wrong with the PSU, but I want to know what to do.

Is it repairable? Do I need to send it back, or is it an issue with my parts and I need a new PSU?

Also, how did it happen in the first place, so it is preventable in the future? I looked up on it a bit, and saw something that said overloading a certain piece of equiptment could have caused power surges and damaged the PSu, and I realised that, naively and stupidly, I had been using the sock intel fan to run games like bf4 and dayz. Could I have overloaded the CPU fan and caused a power surge? My cpu certainly gets hot. Even if it wasn't that, im definitely getting a new heatsink asap. So yeh, any help would be greatly appreciated. Thanks in advance.

hmm, no, those are all very mild. if you had something like a fan with a motor, that might be worth considering. or if you're in an apartment and the wiring is such that there's other unrelated stuff on the same circuit, it might cause an issue.

if the power supply is under warranty, I'd send it in cuz it could just be some borderline parts that were kinda-ok at first but have degraded somewhat. I once had an Antec that did weird things...

I'm not saying it would cause a power surge, but it could be the board calling it that, I don't know. I do know that overheating will shut a computer down, and it getting to 95 within 10 minutes not doing anything is more likely the problem than a power surge. A CPU fan won't draw enough power to do that, but it could be a bad PSU

I don't think it is due to heat, because literally halfway through typing a reply my PC shut down, and I put my hand over the vent to check if it was hot, but it was pretty cool. I haven't played any games on it since I got home, and not playing games means the cpu never gets over 40 degrees, and that's when I have like 10 tabs open. But I appreciate the help dude, any other thoughts?

Ah, well I have a lot plugged into the socket, as I have one of those extenders. I have the PC, monitor, xbox, Alarm clock and at this moment phone charger plugged into the same set of sockets. Could this be a problem? Also, as far as I can tell, nothing else is turning off at the same time

I once had an Antec that did weird things in my file server, and after RMA the new one has been 100% flawless for... what's it been now... 5 years? 6th year now?

your gear doesn't seem like it would load the power supply excessively - I doubt you're pulling more than 450W when gaming anyways.
