In September of 2015, I purchased an EVGA 1000G 80+ Gold PSU, specifically the G1 made by FSP Group, not the more popular G2, which I believe is made by Superflower. It has ran perfectly for me over the past 2 years I've had it, but I recently have had a hiccup with it and I am concerned. Whenever the power supply turns on, it makes a loud tick, which is normal and the supply has always done this. The power supply also makes a ticking noise whenever it turns off, and I am quite used to hearing these ticks. The hiccup that I had with the supply happened approximately a week and a half ago. I was web browsing on my computer (specifications below), with my normal background tasks running, which gives me approx. 30% CPU usage, staying well within the PSU's capability. The PSU suddenly cut and the whole computer turned off. I assumed it was a power cut, as we have been recently having them, but I noticed that my monitor was still on. I turned off the PSU at the wall, and turned it on again. This time, all of the motherboard standby lights were on which tells me that the 5v standby rail was working fine. Then when I pressed the power button, the PSU double ticked and stayed off. The motherboard lights would stay on afterwards, but the PSU would not even tick once unless the capacitors were drained, to which it would then repeat the same behaviour. I did all of the basic system troubleshooting, but I had a strong feeling it was just the PSU causing this, which I concluded after taking the PSU out of the system and using the included tester, where the PSU would repeat this fault. I left it on my desk for about an hour while I wired up a spare power supply so that I could get back to what I was doing, and fill out an RMA request. After that hour had passed, I decided to test the supply again before doing an RMA request. It double ticked again, then I tried it again for a second time, and it double ticked just like all the other attempts. This is where it gets weird. I decided to try it for the third time, having decided that it would be my last attempt. The supply double ticked, but then there was a large spark inside the PSU and the fan started to spin up, then it just worked. I was left very confused, and after numerous attempts at turning the PSU on and off with the tester, it was fine. I put it back into my computer, and it has been fine ever since, even whilst gaming. I am unsure what course of action to take this point, whether it qualifies as a fault and needs to be investigated / fixed, or if it was just an anomaly, and I should be fine. The total power draw of the system when under load is around 490W, calculated by the Outervision PSU calculator. Does anyone have any thoughts as to what could have happened to the supply? I don't usually dust it, but I took a can of compressed air to the PSU 3 days ago, and almost no dust came out, so I don't think the cause of the short was dust.

A video I recorded of the double tick before taking the PSU out of the system:

Also attached is a picture I made in Paint showing where in the PSU the spark came from.
