What wattage PSU do I need?

[cormanxd]

I'm building my first tower and I used 2 different calculators to determine the wattage necessary to run it. I used PCPartPicker.com and Newegg's calculator. PCPartPicker said I need only 386W to run it, but Newegg is saying I need a whopping 1207W. I'm not sure if one of them is glitched or not. I have pinpointed that in Newegg, it's the graphics card (GTX 980) that's causing the problem, saying it needs about 1kw by itself. Here's a link to my build

Completely false, your system atmost will need 750 watts for a SLI capable setup(if not 850 watts) Newegg calculator is wrong.

PSU calculators are deadly accurate if you give them good information.
Unfortunately, some factors are unknowable like your future needs.

PSU wattage is determined by the graphics configuration.
A GTX980 will need only 520w:

I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

The psu you picked is a fine one, but inappropriate.
I put little value in modular or gold rating options.
Pick a tier 1 or 2 620-750w unit from this table:

Some comments on your build:

1. A 4790K runs at 4.0/4.4 stock, no overclocking and exotic liquid cooling needed. Use a simple tower type air cooler. It will be more reliable, quieter, and cool equally well.

2. If you want 16gb, buy a 2 stick ram kit.
1866 speed is fine, but buy a low profile kit to clear any cpu coolers. G.skil, patriot, Kingston are equally good.
Intel does not depend on fast ram.
Ram is sold in kits for a reason.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.

3.
Do yourself a favor and use a SSD for the "C" drive. It makes everything you do much quicker. Use your hard drive for bulk storage.
Intel 730 or Samsung 840/850 240gb would be my pick.

Thanks for the advice! I'l be taking up on all of it. And I am actually getting a 2 stick ram kit, but PCPartPicker didn't have the option for that so I just listed them individually. Also, I was debating getting the Kraken X61 because I have a decent number of animals (2 of which are huskies) in my home plus my backyard is practically a sandpit, which the animals drag in with them, and worry about hair and sand buildup hemorrhaging my ability to keep the damn thing from overheating without having to clean it every day. This could just be me not having a clue about what I'm doing (honestly, I don't), but if you still suggest not getting it I won't. As for the SSD, I'll be getting right on that

I would go for the 850 Evo if you were looking for 250GB. It's going for a good deal on newegg right now with a sale that ends today. http://www.newegg.com/Product/Product.aspx?Item=N82E16820147372&cm_re=850_ssd-_-20-147-372-_-Product

I"m very new to all of this myself but it looked like the 850 was a better one to go with. Do some reading between the two (840 and 850) and see what you come up with. I went with the 850.
