So I've been hearing some strange "popping/creaking" sounds in the back of my computer at times, where the cables are routed in the back of the case. Might this be the cables of the psu and is this bad? I always thought it's just the case creaking since it was still new but yesterday my comp shut down 2x due to the mobo detecting a "PSU power surge" but upon checking it's just a common error among ASUS mobos, besides I was plugged in an avr.

These popping/creaking sounds occur randomly, whether I'm gaming or watching a movie, or typing a word doc or even when left just turned on and i'm doing nothing in the background.

So I can't help but wonder, is this bad and should I check this out? If so, what's a good way of having my PSU/system checked out? My rig is just about 2 months old and so far nothing's wrong with the performance or anything

Specs:
i7 4790k
ASUS sabertooth mark 1 z97
16 GB G Skill ram 1600 CL9
GTX 770
Intel SSD 530 128GB
WD Green x3 4TB
PSU: Corsair RM 750 (fully modular)

The surges Asus motherboards complain about are on the PSU's OUTPUTS. Your AVR and line surge protection are on the PSU's input.

If Asus Anti-Surge complain about surges, it means something is causing dirty power to reach the motherboard. That could be a failing PSU or one of your other components, quite possibly the GPU, changing power draw faster than the PSU can follow.

You can turn off the anti-surge detection if you want to but your random reboot/shutdown will most likely come back in a few weeks/months, once your components will have degraded further and will no longer be able to cope with the surges Anti-Surge was warning you about.

Last summer, my computer got shut down by anti-surge. When I opened my case and took out the PSU to investigate, I found out that my case's bottom filter was packed with dust - I had been forgetting to clean it for too long. What must have happened in my case was that the PSU got hot, its outputs started going out of spec and Anti-Surge tripped before anything got damaged.

Well, my PSU is pretty much brand new, just 2 months old. No issue with dust either as I regularly check the filter of the PSU (my case is an obsidian 750D). What do you suggest I do? I dont' wanna fry my computer or run outta the warranty should my PSU fail in the coming months/years :(

The ideal thing to do would be to use an oscilloscope to find out what is causing anti-surge to trip and proceed from there.

When you have a PSU and GPU that do not want to play nice with each other, age is not necessarily a factor - a few months ago, there was someone who built a new PC using an AX1200 PSU and he had anti-surge tripping on his single GPU. The same PSU worked fine with a different brand video card using the same GPU and the problematic GPU worked fine when using a different PSU. My guess in this case would be that the problematic GPU had input current slew rate (the speed at which the GPU's power goes up and down depending on load) faster than what the PSU can handle, very similar to how not every PSU can gracefully handle Haswell's low-power states.

Not much you can do about it unless you want to start experimenting with splicing capacitors and inductors on your PSU's wires to see if you can filter out hypothetical current spikes from the GPU or swapping out PSUs/GPUs. If you can borrow a known-good decent-quality 600+W PSU, you can start with that.
