PSU to big? uhh ohh... 1st build

[frldyz]

Purchased a Corsair HX750 PSU.
Background:
1. 1st build.
2. 3 mos. ago minimal computer knowledge. Went from learning what wi-fi and Bluetooth is ---> challenging myself to do a build.
3.. Will be basic home PC. Mainly file ( pic and home video storage ), with possible gaming. Nothing crazy....?

What I have so far:
i7 4790k
gigabyte Z97X gaming 3 mobo
Noctua NH-D14 fan/heat sink
Crucial Ballistix ( sport) 16gb RAM - 2 x 8gb sticks
Corsair AX 750 PSU
LG Blu-Ray internal optical drive w/ burner and BDXL
Samsung 500gb 850 PRO SSD
Internal card reader (don't laugh)
Corsair 760T case

What I still need to get:
HDD - for file storage
Another larger External HD
OS _ Leaning towards Win 7. We have 8.1 -HATE it!!!
Will more then likely upgrading my exhaust fan
Would like to add an additional fan on top or underneath HDD or HDD cooler case/fan
GPU- Want to run 3 monitors. Nothing crazy like 4k or too insanely expensive. Mainly because we have lots of windows open ( online ) @ a time.
___________________________
I posted my specs. and needs in a prev. post and got a lot of comments that my PSU is an overkill unless I am doing gaming with a serious GPU. I do intend to purchase a nice GPU. I probally wont need it, but its nice to know I will have a powerful GPU in case I ever need it down the road.
Is there anything wrong with having this PSU that has more power then I need? Will it affect the performance of my machine if this is more then I need?
If the answer is yes. By adding a GPU will that help accommodate the power that is left?
I did purchase this big PSU because I thought it would be ncie to know I have the extra power if I need it in the future? Wrong mentality? Should I return?

If you already have the AX750PS, why did you get a new one? It's never too big, too expensive maybe. You can get away with a cheaper PS unless you need to run some crazy power hungry GFX card.

Hello frldyz,

You may want to hold off on additional fans until you assemble using the fans that come with the case and decide what improvements you would like to make. The 760D is a fairly well ventilated case with stock cooling. But, if you plan on overcloking the CPU, you might want to invest in a couple of 120s for the top. If you are running SLI, you might want an additional 120 for the front.

Either power supply should be fine for your build.

As far as video card, I usually leave it to last, and get the most recent card that my current budget will cover, as I like to keep them for a while.
