Possible Build problems that kill Power Supplies?

So, After building a computer(Asus Maximus VII Hero, Corsair Vengeance RAM, Intel I7-4790k) several months ago and the power supply(Corsair 750W) dying literally the next day after I built it (closer to exploding than dying), I got an RMA and replaced the PSU, then a few months later, the PSU died again, this time taking out my hard drive with it. I got fed up and bought a Thermaltake PSU (still 750W) and buying a Graphics Card (Nvidia GTX 960). Then, just a few days ago, the power supply died, apparently in my sleep, and I've had to RMA that power supply too. Is there ANY way that somehow the way I put together the PC could be doing this, maybe a problem with the motherboard? or maybe the SLIGHT overclocking that the motherboard is capable of doing via the BIOS?

I have no freaking idea as this is my first PC build.

The two most likely culprits I can think of are poor PSU models and power surges from your grid.

1) Do you plug your PSU directly into the wall, or do you have either a 2000+ joule power strip or UPS to help ensure even power?

2) If you were using the Corsair CX line it could be the fault of cheap internal parts. Thermaltake PSU's are often guilty of this as well. You might have just chosen a few bad PSU lines back to back.

I highly doubt your motherboard is to blame, the ASUS Maximus VII Hero is one of the best boards on the market, and isn't known to cause PSU's to fail.

Well, it's good to hear that it can't be the motherboard.

!. I have everything (my PC, TV, Wii, 360, Printer, Router, Modem, and small speaker system) running off of two power strips and an extension cord from one outlet. this may mean that I should invest in a UPS to help the Power supply.

2.Well, I wouldn't be surprised; I'm seemingly having the worst of bad luck with this pc everywhere I turn. Do you have any suggested Power supply manufacturers that notoriously uses well-made parts?

The EVGA G2 750w is one of the best units on the market right now in that wattage range. Make sure you look for the G2 model, as there is a G and also B2 series that aren't quite as good.

Here's a link to it on pcpartpicker:

Power Supply: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($103.86 @ Mac Mall)
Total: $103.86
Prices include shipping, taxes, and discounts when available

So, We figured out what could very well be the problem here. the outlet that I was running everything off of WASN'T GROUNDED...And you can imagine, with me living in a 60 year old house, the amount of problem that could have very well caused.
