Asus Power Supply Surge Detection (Around 2 year system!)

My motherboard, an Asus P8 Z77-V LK, has, as of yesterday morning, been reporting power supply surges from my Corsair CX750M whenever I try to boot up a game. This is strange because the system has been running fine with this power supply for two years, and I see no changes to make it run differently. The most recent change I made to the system was installing a Sabrent internal card reader on Saturday. Sunday night, I had played more than an hour of Team Fortress Two and had no issues, which confuses me even more as to what changed between then and the next morning. So far, I have tried...
-Plugging the computer into multiple locations on my power strip
-Unplugging everything from the power strip save the computer and one monitor (I have two monitors.)
-Plugging the computer directly into the wall
-Unplugging the USB 2.0 card reader I installed on Saturday

The power strip is a little less than a month old, and is very heavy duty.

My system is as follows

Windows 10
Asus P8 Z77-V LK
Intel i5 3579K (Not overclocked)
Corsair CX750M
PNY 2G 960GTX
Western Digital 1TB Hard Drive
PNY 240GB SSD
PNY 16GB DDR3 RAM
2X Optical Drives (Different brands, one is Asus, don't know about the other, but the other was salvaged from an older system, it's been in there for the whole life of the system)
Sabrent internal card reader (Installed Saturday)

As for the actual issue itself, here is what happens: I will boot up a game, be it I Am Bread or Just Cause 3, and the game will run for either a few seconds in the case of I Am Bread, which is installed on the HD and thus takes a while to load, or about 15 seconds in the case of Just Cause 3, which is installed on the SSD. My theory is that something changed and whenever the system requests more power, the motherboard senses this as a surge and crashes the system. As for what changed, I don't know what. One interesting thing that happened is when I booted up Photoshop CC 2015, the power supply surge triggered and crashed the system, but when I booted up Photoshop again on the next power up, the system held up fine. I almost hazard to say that the system can run for slightly longer each time I boot up a game after a crash.

UPDATE: I just played Just Cause 3 for a good thirty seconds and it did not crash the system. This is much longer than I have been able to play the game before. However, after this, I tried booting up I Am Bread, and the power supply surge triggered before the game could even finish loading.
 
Solution
A corsair CX750M power supply has been getting a bad reputation because it is often not reliable, and cannot actually produce 750 Watts.
Your motherboard is warning you that your power supply is failing.

You need to quickly buy a new PSU
A seasonic or EVGA supernova are both really good.
550 genuine Watts should be more than enough for your system

Huh, was not aware the PSU was problematic. Do you know if I can use the same cables with one of the PSUs that you suggested? Because heavens knows wiring all those cables is not something I want to go through again. I also find it odd that the PSU has only just now been giving me problems, especially if it is known to be faulty. Do you think the card reader might have finally pushed it over the edge?

The cables on a PSU are pretty much standard.
Some low quality cheap PSU have less connections, but you should never buy a low quality PSU. (because it can damage the rest of your PC)
Take some pictures of the inside of your PC before you remove your old PSU, then you will know where to connect the new one.

So I realized that while putting in the card reader, a screw fell into my system and I think near the HD. Removed the screw and the problem seems to have gone away. People have said that the Asus Power Surge Detection utility is often faulty and this seems to have fixed things...? I will update if anything else happens.

The problem still persists after a couple of days, though it happens randomly now, and I guess I should get over the whole five stages of grief and buy a new PSU. I was hoping it wouldn't come to this but it would seem that the PSU is truly faulty. From what I've heard Corsair isn't very good with honoring warranties and despite having a three year warranty on the PSU, I'll probably end up buying something from EVGA.

EDIT: Is this any good? http://pcpartpicker.com/part/evga-power-supply-120g10650xr

I have a video of the voltages I monitored through Open Hardware Monitor before it crashed, if that helps. Nothing seemed out of the ordinary except for the crash. The crash is happening randomly now.

I got the new power supply yesterday and reused the cables for the hard drives and fans. I booted up the computer and not only did the fans not come on, but a strange smell started coming from... somewhere. I swapped out the old cables for the new ones and booted up. The BIOS not only failed to detect a boot-able drive, but froze upon me trying to enter the BIOS set up by pressing F2 or Delete. Help?

Wow - you are having bad luck. If I was with you now, then I could have a look at your PC, but all I can do over the internet is advise based on my experience... When my ASUS motherboard reported a power surge, it was caused by a cheap power supply. In your case, sounds like something else is seriously wrong.
All I can say is, whatever is making a burning smell, needs replacing...
Good Luck

I just saw this, You should never ever use the same Cables across PSU's. I don't know why you were told that information. But that smell is probably coming from your Hard Drives that have been burnt out.

You shouldn't have used the same cables especially since your changing PSU brand & wattages.

Lol really, why would you re-use your old PSU's cables with your new PSU instead of the ones that come with it?, you're asking for unnecessary trouble. Unless you meant sata-data and molex cables like the ones which come bundled with motherboards and graphic cards, in which case there wouldn't be a problem.

I had the same problem and I finally managed to find a solution: before changing your PSU, check your cables. I had poorly connected power cable to the motherboard which caused the power surge.
