Hey guys i'm planning a build for my gaming computer. i need to find out possible power usage. So far this is the parts list:

Cpu- i5 3570k will be overclocked to about 4.5Ghz if i can.
gpu- gtx 780 1 or 2 in Sli mode
mobo- sabertooth z77
case- corsair 900d
ssd- 1 80gb os and maybe a 256 for games
hdd- 2 2tb
ram- 16gb dont know who for ram yet. any input would be nice.
the cpu and gpu(s) will be water cool 1 480 rad and a 360 rad.

if i am missing anything let me know. This will be my first build so any advice would be nice but try to be tactful about it. Some of the parts i chose because i like the look such as the sabertooth.

It's up to you to really choose what kind of processor you want really. Haswell makes more sense to me, since it come standard with more SATA III ports than the LGA 1155 socket motherboards do. That might be a feature to consider.
Yea certain cards do come with waterblocks already attached, they are more expensive it you saw the price on those EVGA cards, but you'll have a warranty.
As far improvement, if you want to spend the extra and get an I7, depending on what your doing, it might make more sense to spend that extra $100 on it. An overclocked I5 will do you fine, but that I7 might mean that much more if your doing heavily threaded applications.

For your water loop, just friendly advise, and I know this from doing other...

The biggest concern for ya is the power consumption. Generally GTX 780 is a powerful gaming gfx which needs a 8-pin and a 6-pin PCI-E Power conductor to power it (Its TDP is 240W), if for sli the TDP will reach 480W. Plus u wanna OC a 3570K CPU which has a 80W TDP, plus your coolers, mobo, HDD, SSD, Optical Drive which have a roughly 150W TDP, the rig's total TDP can reach 710W! So, as a PSU has a 80% efficiency when in full load if u get SLI 780 or planning to make SLI, u should at least look for the PSU which has more than 900W power and at least has 80-plus bronze certificate.

Because such full load can bring much heat, and that causes the PSU's efficiency to decrease. So don't count on this PSU has 80% efficiency forever, leave some space for the whole rig's stability. So the PSU should at least has 710W/70%=1000W power if u wanna enable SLI or 470W/70%=700W power if u use solely a 780 and have no plan to enable SLI.

And to let the PSU sustain the heat and prolong its life, choose the good PSU brands like Corsair, XFX, OCZ, Cougar, etc. and choose the PSU which has modular design (don't choose semi- or non-modular 'cause that will let the PSU vulnerable to heat and shorten its life)

Here is one of the 1050W PSU I would like to recommend for SLI: http://pcpartpicker.com/part/xfx-power-supply-p11050befx

or a 700W one for single 780: http://pcpartpicker.com/part/ocz-power-supply-oczzt750w

Another thread to talk about other parts:

CPU: good choice, although u could go for 4670K but it'll gain only 5% more performance compared with 3570K, plus u should change your mobo to a Z87 one.

Mobo: Fancy but the quality is solid.

RAM: If u'r rich enough go for 16GB anyway. Do u mean 2*8GB pair or 4*4GB pair? 8GB should be enough no for gaming IMO.

HDD: U get 2 HDDs for RAID?! A good SSD will be even faster than RAID HDDs. And u get 2 separate SSD for OS and games? OMG I wish I have such money... (Actually one 256GB SSD is enough though.)

Case: Should be solid too

Cooler: Water coolers can suppress more heat than air-flow coolers anyway

And u might need a OS (Better use Windows 8 'cause it's faster than Windows 7 on the same build) and a Optical Drive (Games and OS are all recorded on Discs) And a monitor if u don't have one. (Also mouse, keyboard, speakers)

I guess this would be about what your build would look like. Changed the case,CPU, Motherboard, and chose a bigger SSD.

1)Went ahead an put in the LGA 1150 socket, since its the newest, if your gonna spend big, which it seems like you are, might as well get the newest.
2)The AsRock Extreme 4 board is a solid motherboard, very very quick on boot up times with a SSD
3) No sense in spending nearly $400 an a case, you can get the same from an full Tower case, for half that price.
4) if Your planning on overclocking that high, i'd definitly recommend a liquid cooler.
5) I guess this boils down to the original point of this post, the power Supply. This comes down to whether you plan on doing SLI or not. with 2 780's dropped in, your going to want 1000 plus PSU, with just 1 however, a Corsair 750-800W PSU would do you more than enough
6)I tried to include everything you wanted, so you could look at the max price and see if its more than you thought, or less. Also, the RAM is a 2x8 gig sticks, so you have the possibility of getting 32Gigs if you want it.

yea would be something like that the reason for the case is the water cooling loop will be custom. the space and look of the case i like it would make taking down the loop a lot easier for me. i am looking at doing the sli mode. so lets go with yes on it for the power calculations. i dont want the 4th gen core just becuase i dont really see the need to pay the price for a little preformance but i could be wrong let me know. as i mention some parts are also for the look the colors i want are black and green but if there is something a lot better then what i listed let me know why its better and i will look at if i like i will take that instead.
oh and dont get me wrong i really apretiate the input you two have given me and am looking at the parts you have recommended to me. sorry for spelling.

You didn't mention anything about the custom loop, or that you were going for an very certain look with certain colors, or i could have kept a color scheme in line with what you wanted, not to difficult, I'll attach another build at the bottom.
The only reason I recommended Haswell instead of Ivy Bridge is because LGA 1155 is done, what's out is more than likely it. Intel does that tic tok kind of cycle(Release new socket, then the following year improve on it). So Haswell might only be a 5% improvement over ivy Bridge, but the next iteration could be a lot more. With the amount that your prepared to spend might want to consider LGA 2011
If your doing that custom loop, I'm guessing that's going to include the GPU's to, if you don't get a card that already has a water block attached, i think ASUS and EVGA might make a few, you're going to void those warrenties i do believe by removing their shroud and attaching your own water block. So really with this system your look at close to $3000-$3400 with that custom loop, and that's a pretty penny

If you want an LGA 2011 Here's what you would be looking at, before you even consider the custom loop. i included the EVGA 780 that comes with the water block attached, so you want have void your warrenty, and also Crucial Tatical Tracer RAM(16 gig) comes with red/green LED's on it.

Now if you want a more normal build for LGA 1150 there's this. Same case, different socket.
http://pcpartpicker.com/p/1kvTT

Now both prices are before you want the custom loop. I'm not trying to defer you from doing it, I want to do one one day too, but your going to add another $300-$400 to that probably if not more by the time you've bought the fittings, hoses, Water Block, Liquid, Pump, Radiators, and more before you're done. Apparently money isn't an issue however, so do you what you want, more power to you.

i know the water loop would add around 500 to the cost of the build. I didnt know that gpu cards came with a block on it which is really nice to know. i will look at the haswell cpu since the one you posted was about the same price as the one i was going to get. the reasoning behind what you say about the cpu makes sense. If there is any other part that can be improved on let me know. i dont mine spending the money now becuase if i spend it now i wont have to spend much later and i dont plan on building it for about another few months. sorry about not saying anything about the custom loop.

For your water loop, just friendly advise, and I know this from doing other plumbing, make sure your fittings are tight to begin with, then as your system breaks in, keep checking those fittings and tightening as needed, because as that water heats up and cools down the rubber will tend to shink and stretch. I'd hate to see that much money wasted because your fittings aren't tight. It'll could take a up to a week for them to really set, or it could be longer depending on the amount of time you use it. Even then, regular checks never hurt anything either.
