If I do a 3 Way SLI for this card, How much of a PSU would I need? I currently have 1000w but I'm leaning towards a 1600w for future use.

Hey. As per specification each of these beauties has a 250W power consumption. So it recommendable to get a 1200w or more PSU for three of this kind. You'll be more than well served with a 1600w PSU for a 3 WAY SLI. Cheers!. http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780/specifications

Dear friend, I strongly recommend at least 300-350 watts per video card. So just for the cards you would need 900-1050 watts. You still need some more power to the rest of the system. Get that 1600 psu ASAP...

I have a 1200watt power supply, and I have the computer plugged into a 15 amp household circuit with nothing else but my computer system running on that circuit. I tried plugging my computer, monitor, and speakers into a UPS so that I could turn all on at once, but that trips the UPS every time due to electrical surge. I have to turn on the computer, then the monitor, then the speakers about 15 - 30 seconds apart. If you want to use a 1600 watt supply, I would make sure you're on a 20 amp circuit.

I remember correct I use 750W not sure if can run with sli or not i only got 1 card

This is a really great card. however, your concern is correct. I wouldn't try running it on a power supply that is less then 700w just to be safe. I currently run a 1100w Therm, and have had no problems.

I believe the recommended minimum power supply for two GTX 780 cards is 800W. From personal experience though, it is always better to have a power supply that exceeds the recommended minimum. I think your best bet would be to go with the 1000W.

Considering how this psu failed in 6 months when i have been doing heavy duty gaming.. I think the answer is no. But if you were asking if this unit can supply enough wattage for your build, the answer is yes. UNLESS you are running SLI/Crossfire, in which case go for an 750 or 800W.

I used a 700 watt Seasonic 80 plus. I had a a FX 6300 in a Gigabyte z71 I believe. I love the case. Lots of room. What kind of video card are you planning getting. I had 2 Gtx 550ti in sli my 700 ran perfect.

It would depend on what else is running in your system, but I would recommend 500w+. This particular card is pretty efficient on power. At peak performance it can consume about 160-170watts. That's taxing it pretty hard though. But throw in a couple hard drives, optical drive, fans, and any power consuming usb peripherals, along with whatever your motherboard and processor use, and you will have an issue. Most retail systems come with a 300watt psu and they don't have a ton of overhead. 400 watts isn't much higher. I think you are asking for trouble unless you aren't planning on taxing the system with high end games. I would recommend a 600w but I think you could get away with 500 watts.

I would like to turn you away from this PSU; I ran two GTX cards in SLI and this power supply didn't hold up too well. I recommend NOT getting this power supply for crossfire. It's not power efficient, it doesn't have the best stable voltage, and lastly 600 watts is a little low for multiple GPUs. Also when I was doing SLI on this I swear it almost overheated and cooked to death. You should get a bronze-rated Corsair like the CX750 instead. I upgraded from this PSU to the HX750, at the time I bought it, it was around $120. Best power supply I think money can buy that isn't overkill. Gold rated, modular, and the fan doesn't run at all on idle use. That's another thing, I had noise issues with this PSU. Do yourself a favor, get a good power supply and avoid this. I don't want to call it junk, it was pretty decent, but honestly I wish I went with something better to begin with. I think Corsair is the best name for PSUs. Either them or Cooler Master also has some nice models.

I run a 700 watt supply. It is more than adequate. A 320 should be enough. I use an extra fan hence extra power. The card is awesome. Updates regularly highly recommend.

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.

I'm running this card with an i7-3770k, 16GB RAM, HDD, blu ray drive, loads of fans using a 300W PSU. All is well. It's about 65w for the card.

Hey Josh, I can't comment on the 1000 of each PSU. My decision is this. My choice was between the Corsair 1200i and the EVGA 1200 P2. I choose the EVGA for a couple of reasons. First off, the 10 year warranty, and almost a hundred dollar difference. Both of these are very good psu's. You can't do wrong with either. However I personally don't care for the (i) interface. To me however, 1200 watts is not an overkill. Simply because my rig is build for the long future (4k). And knowing that my psu has a 10 year warranty. No brainer. Like I said, you can't go wrong with either. However look at the warranty, future, and price. GAME ON, my friend

I used a 650 W PSU, but it depends on your mobo/cpu requirements. I referred to the Puget Systems site for analysis and guidance. You are likely OK - I built in some headroom for expansion later.

Too late for you know obviously being a month later after question but in case anyone reads this deciding as well. Irregardless of the wattage, you need 30 amps or more. If you get a psu with a solid single rail all you need is 30 because all these video cards give an estimate assuming the amps are spread out on 2 or more separate 12v rails. The guy with the SFX 450W is actually more than enough because it contains a single rail with 36 amps. Don't listen to the people who say you need 650 amps, that's ridiculous unless you plan on doing sli.

Yes...very good graphics card...I do a lot of CAD and it works fine. If the EVGA 500w is a power supply, I would bump up to more like 750, no, I'd make it a 1000W.

The latest EVGA drivers support 3-way and Quad SLI. As others have already stated, motherboard support is the first hurdle. The second hurdle is that you would need a monster PSU. Each card can draw up to 250 W. Each card also requires 2 x 8-pin PCI-E power connectors.

I did not see where it stated there were 30amps per 12v+ rail. If your intent is to SLI or Cross Fire, you should look for a single 12V+ rail PSU. EVGA makes a 1300 and 1600 that both have single rails. Total the amp draw of each VGA card you are using. Then subtract that total from the available amps of the single 12V+ rail. If there are enough amps left to power the rest of your computer, then you will be fine. The 1300 watt EVGA may be enough at around 100 amps, and is less than the cost of this one. The quality is 100% better as well. I had poor luck with this thing. Hope this helps.
