Hi, I own a Seasonic G750 power supply. I've had problems in the past where my motherboard wouldn't recognize my hard drive when a my GPU overclocked causes a crash. I remedied this in the past by flipping the power supply switch off and holding the power button in for 30 seconds. I really don't know if this helps but I haven't had the problem with my hard drive since and it fixed it the last time I had the problem.

Anyways when I flipped the power supply on (switch) it made a loud pop sound. I was kinda scared to boot up the PC because I know a pop sound is never a good thing. Anyways the PC booted up fine. Everything seems to be working perfectly normal however I haven't tried to play a game since.

I emailed Seasonic about this for their help when they get back to me should I request a RMA?

--Specs--
i5 6600 (no overclock)
Cryorig h7 CPU cooler
980ti Classified
250GB SSD
WD blue 1TB
8gbs of ram

Beyond the GPU overclock nothing else was overclocked and I can't see this PC taking more then 500 watts max under the worst case so my power supply isn't under powered. I know people don't consider the G750 the best of the best but its a solid tier 2 PSU.

Any advice? I don't really plan on using the PC any time soon now and if I do I'm not going to game on it.... Basically I don't want to stress test the PSU.

Thank you for your time!

No, no smoke not noticeably smell just the pop sound. The switch has a click to it but the sound was a noticeable popping sound.

It may have been the switch sparking when you were switching it on. How old is the power supply? That generally happens over years of frequent on and off cycles, but a power supply switch doesn't really get that much action. It may be that the switch itself was of bad build quality/defective but I can't say for certain.

The power supply is about a year old but I've only had a graphics card in the system for about 3 months so the other 9 months of its life was pretty much easy mode. I typically don't switch it off I've probably only done it 4-5 times total. I'm just concerned over the parts in the PC. Still tho I don't really see a pop or spark as safe so I am most likely going to request a RMA when I hear back from Seasonic.
