Ok so I'm going to build a new rig and this the psu that I'm going to get (pcpartpicker com/user/ArcSpectre/saved/NsqBD3) Should I go down to an 800w?

If you ever want to upgrade your rig you'll want a psu to handle it the supernova is plenty if power for anything you want I would go with this just to save money latter on instead of buying another psu to upgrade

Here is where I start when I want to calculate the amount needed: http://www.extreme.outervision.com/psucalculatorlite.jsp (Although it looks like it doesn't have your CPU yet.)You'll probably be fine with an 800w power supply, although you'll need to make sure the rail(s) can handle the graphics card. Also, will you be (in the future) adding another graphics card? If so, I'd say get the 1300w one and then you won't ever have to worry about it.

An 800W power supply would handle the rig outlined in your parts list, but you might want to purchase a power supply larger than 800W now if you wish to later add more GTX 780s in SLI.

That should be fine. It depends on what MoBo and CPU you're using, fans, and if you plan on doing any overclocking. I personally went with a 750w PSU to make sure I wouldn't have any hiccups.

I am making a WoW computer with the A10 65W and SSD. That alone uses 94W This PSU has a peak of 200W and a constant of 160W. You will be fine,

Yes, it recommends a minimum system PSU of 500W. 600W will be fine as long as you are using this as a single card (not SLI). Do yourself a favor and get a good PSU from a reputable brand (e.g. Seasonic). Don't skimp on the quality of the PSU to save a couple bucks.

I'm running one with a Corsair 850 watt PSU, and wouldn't go any lower than that for this card and any decent kick-ass mobo, MINIMUM. If you're going to get the "good stuff", power it with a good, high quality power supply so you'll have no regrets down the road.

Generally a 600W PS should work fine.If it's a new build with the top or higher end components I would go with a least 700W min. I realy would not go below 700W to be safe that way you can add HDs DVDs later and be safe.A little extra won't hurt and modular keeps it clean and helps with air flow. You also need to check and clean the dust inside once a year or as needed.

You should be fine with 750 W. And corsair's CS psu's are fine products. However, I would reconsider the CS series. Not really in line with the rest of the config. While your non overclocked setup will peak just above 600W, making 750 W an efficient PSU, a platinium PSU would be even more efficient, hence cooler and quieter; even save you a few bucks in the long run if you're an avid gamer. 600 W does leave its mark on the energy bill. Another choice : I like the RM series; not really that more expensive and go fanless outside of games. If you can find a way to quiet down your GPU fan (not on the quiet side, even idle) you'll be glad for the tiny price premium. Good gaming ! [EDIT]just to make sure : because of the graphics card, when picking your pSU, make sure each pci cable can handle 28A and the combined 12V rails 50A. This is the case here and should be for any 700W+ PSU. Better safe than sorry, so double check !

You need to upgrade to 500. My PSU was only 300 W and I upgraded to a 500 W Corsair unit. The PSUs aren't that expensive. I didn't want to take the chance. Haven't had any problems.

I would get a big higher wattage on your place. There is a good tool from ASUS to calculate the approximate PSU power you will require for your system: http://support.asus.com/powersupply.aspx

in theory yes. in reality, probably not. you'll burn out the psu quicker. Plus we don't know what mobo or psu brand (and their rating), and overclocking you might be doing. The thing is you don't want to run near full capacity of the psu (shorten lifespan) if you runing amd x6, 8gb ram, regular mobo, dvd/cdrw combo drive, 2 7200 rpm hard drive, you're about 380 w (estimate). Ultimately its up to you. Safe bet is to get different psu.

Personally, I like to have a little more than required so i would go with an 850W PSU, so to answer your question, yes this one will work fine. You could also use a 750W PSU as well though.

Well, I've seen power draw benchmarks of 2 Crossfire 290xs range from around 600-750. So I would would say a PSU thats a tad over 1000 W total. Don't cheap out on your PSU either, get something with a reputable OEM. Would hate to see your cards go up in smoke.

I would get at least a 450 W PSU... preferably 600 W. I was running into issues with a 450 W, but upgrading to 650 solved all my issues.

Yes, if it's an atx mobo that is an atx psu., but you should be more specific about your power needs. Is 750 enough or too much? Find a psu calculator online. It will help you.

400 watt or greater is the recommendation for this model. You should calculate how your psu is destrobuting it's power to make sure you can delegate enough to the card

Yes definitely, and if you don't trust me or anyone else here, go to pcpartpicker.com and put in all the parts to see the estimated wattage. This PSU has 80% bronze efficiency so you should leave around 150W just to be safe.

It should be fine, but just. Im running an i52500@3.7 and my 780@1ghz with a Corsair AX750.. My system consumes around 450w at full load. You may want to try it out first and then upgrade your Psu if you need to, specially if you are going to OC. Which I assume you will. But again, it should be fine to be honest. Have you simulated your power consumption online?
