The corsair tx750v2's 12 volt rail goes up to 62 amps and has 4 6+2pin pin PCIE connectors could SLI a pair of 770s with your cpu.

Also for reference The corsair tx850v2's 12 volt rail goes up to 70 amps and has 4 6+2pin pin PCIE connectors.
This is the current PSU I am using with 2 heavily overclocked 965 core 2400 mem @1.075 volts from 822 core and 2003 mem @1.025 volts 560 ti cards in SLI with a overclocked 2600k between 4.5 and 4.9 ghz depending on winter or summer for well over 2 years.
And that's with Nvidia saying a single 560ti need 30 amps and 170 watts on the 12 volt rails and I am using 2 of them overclocked a good 20% so you can say i a pulling 36 amps or better along with 205 watts or better x2 so that would put me at 72 amps 2 amps over my PSU's limit. I just added 20% to the power since i am using more then stock voltage and a 20% increase in core and memory speed, But it is probably 25% perhaps higher then that since when you overclock it greatly increases leakage and power draw once you add voltage and overclock MHZ.... Plus that does not include my 2600k @ 1.3+ volts 4500mhz+ 3x 2tb HDD, 1 SSD, 1 AIO 120mm liquid cooing system with a pump, 5x 120mm fans, 2x 200mm fans and a lighted USB Black widow ultimate keyboard and matching Imperator mouse. Also my PSU's 140mm fan is heat controlled and it rarely turns on ..in fact I have to clean my PC every 3 months from dust buildup on all my 200mm, 120mm fans and GPU fans etc. But my PSU fan is always clean so I do not even think it comes on. Since it only turns on when it gets hot enough.

I figured it might help you decide since NVIDIA and AMD greatly inflate there power requirements for there video cards. My 560 tis are built on a 40nm process with a 360mm squared die with 1950 million transistors. The gtx 770 are built on a 28nm process with a 294mm squared die with 3540 million transistors and a peak power consumption of 230 watts. For comparisons sake A sandy Bridge-E 3970x with 4x4gb quad channel memory @ 4800mhz "wow":) system with a GTX 770 fully loaded on crysis 3 with max settings @ 2560x1440 the WHOLE system pulls only 475 watts. Under a 2d idle It pulls 225 watts from the wall socket. So the actual wattage pulled is a good 10-25% less once you consider efficiency of the PSU itself converting 120v to 12v. Below is the link to the article.

I hope this helps in some way and makes some sense

Also 90 to 100 amps is all that is needed for a mig welder that runs off of 115 volts so 42 amps from a 770 card alone, I highly doubt it.

The GTX 780 is 265W with boost, and most GPU power draw these days are on the 12V. So 265/12 = 22amps. Add the fan, RAM, and other electronic components, 25-30A is more like it. Are you sure you are reading 42A for 1 card or in SLI configuration?

First and for most, I apologize to JustAnEngineer, Morphine, Chrispy, and Prestige Worldwide or anyone else I offend.This is hard for me to bite the bullet, but I was wrong.I have been looking at benchmarks from alot of different sites, and found out something I never considered.The 8350 has to be overclocked really high just to compete with Intel at STOCK speeds.Throw in the frame latencies with AMD, and the value goes way down for gaming.Even worse the power consumption on those higher clocks will make it run very hot.A Haswell with good cooling and a mild overclock will make a great gaming cpu.

Thank-You Some very good information. It sure sounds like NVIDIA and AMD inflate there power requirements, but not sure about the GTX 770. I have a TX 750. It's 62 amps on the +12 rail, and 1 year old. The fan on that psu will cycle down on low loads, but never turn off. Its designed that way. Older version. It's connected to a Antec DF 85 using 7 fans, not counting the two on a 212 Evo. Overclocked FX 6300 @ 4.5g , ssd, 4 hdd's, 2 dvd burners, fan controller, sound card, nic card, and a 660 SC. That power supply has run great for the last year 24/7.

In my other pc I have a Corsair TX 650 V2. That Fan does cycle on heat. It's basically a thermal overload switch.Weird. A thermal overload is normally a fail safe switch, not a activation switch. In HVAC terms, on a compressor it works that way. If the compressor does not turn off, or gets to hot, the overload switch will trip, and break the circuit. I guess there designed to work either way.

EDIT: you are very welcome please read below.
The GTX 770 is just a faster GTX680 that was supposed to be a midrange card but performed so well Nvidia made the 680 there #1 card. It is a very power efficient card for the horsepower it gives you. Not like the GTX 560ti ,570 and 580s which were power hogs.

Trust me your tx 750 will run a 770 overclocked and your CPU overclcocked along with your soundcard we wont be overclocking that..J/K....without a worry in the world I repeat, without a worry in the world.
I bet if you had 2 770s your tx750 would power your whole system, I would bet a $100 on it. But I would not run SLI on a AMD board, it just does not perform as well as intels SLI.
Here is a link to a PSU power calculator...I put in everyhing in your system including a gtx 770 5 120mm fans ,controllerand 2 7200rpm HDD's ETC. and it came up with a minimum PSU of 480 watts and recommended 530 watts. See for yourself http://www.extreme.outervision.com/PSUEngine

As for the network card I bet you will get better ping times using the Onboard GIGABIT connection on your motherboard. You can find that out right now. Just enable both and plug your network cable into your motherboards gigabit network port and do a advanced speed test from http://www.megapath.com/speedtestplus/ select a city closest to you...I am between washington and new york and washington gives me the best speeds in pings, the unplug it from the motherboard and use the add in card and do the same tests and see for yourself.
As for worrying about taking the network load or the power usage from off the motherboard you are not. I bet the add in gigabit card will add latency and power use over the onboard gigabit. Onboard has a smaller footprint so less wattage along with shorter traces along the board to get your info to and from.

I would go with the XSPC option rather than the AIO system.
For one, it's cheaper, and secondly, it's a higher-quality cooling system. Plus, you can throw a couple of waterblocks on your 760's and have a reallllly nice full-water system.

My last rig had an i5 750 on water with a 2PCB GTX 295 on water in the same loop.

On my current rig, only my CPU is in a water loop. I haven't ventured into water on the GTX 670s I am now using, but having a GPU in your water loop is phenomenal. Drastically lower temps and so much noise eliminated by not having GPU fans spinning up while you game.

Prestige Worldwide wrote:

A second rad couldn't hurt to include the GPUs in the loop. You might be able to pull it off with just 1 240mm rad but it would be for the best to have 2.

When I had the i5 750 and GTX 295 in the same loop, I had 1 240mm modded into the front intake of an Antec 900 with another 120mm rad on my rear exhaust.

If I were to put my gpus on water in my current rig, I would add another 240mm rad in my front intake, as I have my current one top-mounted.

Another option would be to choose individual parts instead of the pre-selected XSPC setup and get a thick (60mm) 240mm rad, that might also do the trick instead of running two rads and simplify your loop.

If a significant overclock for Haswell is the goal here, then wouldn't uncapping the IHS so you can replace the TIM be more important then going with water and stuff?

Excellent monitor choice for gaming, you will be amazed by the high refresh rate, it's something that has to be seen to be believed. Been 120hz for a year or so and would never go back.

2. The constant frame interval in milliseconds beyond which they cannot see any difference
