PSU's and Coolers for this build

[astritloxha]

Ok guys, quick outline of my upcoming build:
-GTX 770/780 (hopefully my christmas bonus should be enough for the latter)
-i5-4670
-8gb kingston 1600MHz XMP
-ASUS® Z87-A
-Either a 550W or 650W PSU depending on the GPU I get
-Choice of coolers between: CoolerMaster 120M CPU Cooler, Corsair H60 CPU Cooler, Corsair H80i CPU Cooler
-Finally, no over-clocking on any components.

Now for the questions:
1. I've scoured the internet and feedback is inconclusive where I've looked. It is, how much will a bigger PSU increase an electricity bill. I always see people saying, "you aren't always using that much power", so when am I using that much power? I am a gamer and general media viewer... this build would obviously be used for high end gaming, would that push the PSU to its limits and increase my electricity bill with frequent use?

2. Which Cooler is more suitable for this build?

I understand it's quite a bit of a mouthful, but I'm in the dark at the moment...

Thanks in advance.

As you're not going to overclock, the stock cooler is enough, you can get a Cooler Master Hyper 212 EVO for your peace of mind if you want.

The size of the PSU doesn't impact the size of your electricity bill as the PSU only uses what it needs, even more, a bigger PSU can actually LOWER your bill as under less load it will be more efficient.

Thanks very much Pepito, I'm still confused at why a bigger PSU wont increase my bill (a bigger PSU because said components have a higher energy draw), but then again I guess I should leave that to my betters 😉

Thanks again

Here's a link to Anandtech where they explain the concept of PSU Efficiency: http://www.anandtech.com/show/2624/3

I find it fairly educative and better that the way I was thinking to explain the concept.

Cheers, always nice to expand your knowledge, I've just not known where to look
