What power supply would power 6 cards? Let's say you are using the new 290 or 290x tri x cards from sapphire. How would you power those?

You will need multiple power supplies on two home power circuits. Most home circuits cannot handle one massive PS (1800+ watts) for 6 cards. Figure 300 watts per card x the number of cards (when mining). Most suggest a 750+ PS with at least a 60 amp 12 volt rail to support two cards running non-stop. If you want to support more than two cards per PS, then choose a 1K or above PS for the 290(x) but I wouldn't recommend &gt;3 cards for a 1200 watt PS. To use multiple PS with one mining rig use a PS splicer (sold on Amazon) or use g00gle and search for "using multiple PS in one computer". There are free methods to start up PS without an adapter.

Nice card! It consumes about 180-185 W. Depending on what you're running it in and how much stuff you've got in you're box, you may want to bump it up a notch. You can check the AMD site (or call them) if you have doubts. The site should have recommended PS ratings.

2 of most. But mostly depends on the power draw of the cards. You can google that.

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

Officially, you should have a 500W power supply per each card, but I run four 780Ti's with this power supply with out an issue. Make sure you pay attention to what plugs are for GPU 1,2,3 and 4.

That's not what Sapphire says... I know the other person here said it was a lower power requirement card but in all honesty you should listen to the manufacturer when they tell you the minimum requirements. In this case this card requires at least a 500w PSU. "500 Watt Power Supply is required. 600WattPower Supply is recommended for CrossFireX System." - http://www.sapphiretech.com/presentation/product/product_index.aspx?pid=2040&lid=1#

I ran it with a 300w and it ran fine. However, for the price, there are better cards you can get, like the 7750 and 7770 that aren't very expensive, but perform very well.

I can tell you this, and it might not directly answer your question:the powersupply is not designed to be very powerful, it was made to save on power costs. It is also non-standard, so you need to take that into account.ALSO,It has 2 displayports, out of the box. although I haven't tried hooking up 2 at the same time... so you may just need one additional card

I have the GTX 650 2GB super-clocked, which consumes more power than the gtx 750ti and a AMD Phenom II X4. My computer works without any problems. I would not recommend to have more than one card with this power supply.

Yes, you need six pin power. Otherwise it will just lock up. I had that problem even though I had a six pin power plug in my old PSU but it was unable to meet the amperage requirement for this card on the 12V rail

I just did some research for you. You should be able to use the card on your system. AMD recommends a 500 watt power supply. Your computer has 460 watt power supply. You should be fine, as users on forums have said they they run the card on similar power supplies to yours. Sapphire gives you a 2 year warranty. I have the card and it gives you great performance for the price. Have a Merry Christmas.

Yes it will, but dang, you're gonna need a big PSU :P. I think my 900Watt won't even power a second 290X GPU lol. If you want a new GPU, this is the one to get. ATLEAST 200Fps Every game. Cod ghost, perfect to play with , besides because there is optimization problems in the game, I get a 0.2 second lag every 10 mins lol. No bad, xD.

at least 500V, if you are running a 980 or a 290x i recommend a 650 or 750.

It has the proper connectors to do so, but if you're using a 7770, this probably isn't the best power supply to use. While it's rated as a 500W psu, that's only peak output. I believe it actually averages about 380W to 425W. I would recommend looking at Thermaltake or Coolermaster for one of their 600W+ power supplies for a better experience. That said, this power supply is cheap and sufficient for most computing needs. For gaming, do like I suggested and spend a bit extra for a better, higher-wattage power supply.

Doing some research it's maximum power draw is 150w although most of the time will be much since it regulates power based on how hard you push the card. The minimum power supply to use is a 500 with a 6 pin aux power connector. Personally I would have at least a 600-700 just to allow for future upgrades.

Bear in mind, the PSU they "require" isn't about what the card needs; it's an assumption about the overall needs of computers the manufacturer figures might be needed. This card requires no power other than the PCI express lane --- that only supplies 75 watts. So this thing only needs 75 watts or less for itself.

It is recommended that you use a 400 watt power supply by AMD, but in reality all this is for is to save themselves from hearing about defective cards from users that may have cheap or low end power supplies. I have one of these running in my secondary rigs with a 300 watt power supply without any issues what so ever. Though 300 Watts is as low as I would go.
