Okay so I FINALLY got my new PC, with following specs:

i7 4790k
MSI Gaming 5
Corsair h100i GTX
Corsair Vengeance 16gb DDR3 RAM @ 2400MHz
EVGA SC GTX 980ti (probably trading in for MSI Gaming 6G soon though)
EVGA Gold 1050W PSU
ASUS ROG Swift

And then some SSDs and HDDs and all that.

Okay here's the problem: so I've put it together and it has not been able to boot for TEN hours. Ten. I take it in to Micro Center (the store I got all the parts from), and they connect the front I/O panel jumpers directly to the mobo instead of to the adapter MSI included, and, it worked. I checked turning it on/off there multiple times. I even added two more fan power units at the store and it worked.

I drive home, plug it in, and it DOESN'T work again.

My theories:

1. The store had the PSU plugged into their own power cable, not my own that came with the unit. The power cable could be screwy on my end?

2. The store plugged my computer, using their own cable, into their wall directly. Mine, for the moment, is going into a power strip that then goes into an extension cord. Might this also or instead be the problem?

I am at least a little bit more relieved in that I know I didn't botch the installation, because they were able to boot it (I still have yet to install Windows...)...any help is appreciated guys. Thanks!

First never use a power strip hooked to an extension cable.
I would by pass the power strip first to see if that was an issue plug the computer straight into the wall that way you have narrowed it down to maybe the cable to the wall or the psu or at least some thing in the computer. Even if its not where you want it plug it directly into the wall to see if it powers on then if it does plug it into the power strip. Or plug the power strip in and plug a lamp or something into it to see if all the slots work.. Never plug a power strip into an extension cord unles you have like an 8 gauge extension cord, then its probably still not a good thing to do.

galeener is correct on what he covered. There is also the possibility that your wall power is flaky, i.e. low or high voltage. Personally, I'd use a UPS plugged directly into the wall. Most UPSs these days have some power conditioning circuitry that cleans up the power somewhat.

Ya i had a part where my next step would be to take it to a friends house and plug it in that would show he has problems on the circuit he was using but some how my edit didnt go. UPS is always a good thing if you can get one it can not only save your data but also your system.
It could be the wall circuit you could try one thats not on the same circuit in your house also or get a cheap plug tester at home depot or lowes or somewhere just to make sure.
