what wattage of psu would it take to run 4 of these 49 290x? or would it take 2 psu's connected with something like add2psu?thanks!

If you want to run 4 of these and the rest of the system off one PSU, you need a 1500-1600 watt PSU. I run 4 Sapphire R9-290's, and at peak usage I draw over 1500 watts from my 1600-watt PSU.

You need a PSU with 2-8 pin and 2-6 pin connectors for Crossfire, One 8 pin and One 6 pin for a single GPU.Yon should use a 850Watt PSU for a Single GPU, and a 1000Watt PSU for 2 GPU's. I have Corsair RM 1000Watt for my 2 GPU's.

This cad recommends a power supply (psu) with at least 600w total. You also need a motherboard with an open PCIe slot, which shouldn't be an issue if your board isn't ancient. Your psu will also need to have an available 6 pin and 8 pin connector. The 290 requires good cooling too. You will also need a good bit of space in your tower to fit in. It's probably some 10 inches long. This is a high end enthusiast card, the cpu will need to be powerful too to avoid bottlenecking.

hmm Yeah but if you don't have to much components how 4 hard disk 2 graphics video, fan cooler.... i think Work great with that PSU but... you need more for you want SLI or CROSSFIRE... You choice.

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.

I'm using 850W one for cross fire. I think 450W would be fine for single card, but it depends on your other hardwares.

http://www.extreme.outervision.com/PSUEngineThis site will help you with specifics for your computer, but it looks like the R9 290X uses about 330~ watts on its own, so I would want at least 600~650, if you have 80 certified (It has to do with the efficency, most PSUs are that efficient at least, and 80 silver + is more common). If you have a lot of HDDs or things you might even consider going up as high as a 700 watt. I hope this helps! It's a sweet card!

Hey Ronel,I have a 750 watt power supply that I am using with this card. However, a standard power supply one with no less than 350 watts should be enough to run the card with no problems. I would recommend getting a 400 to 450 watt power supply if you will be using this card for gaming.

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.

Depending on how many other items you have within your desktop will depend on what power you'll need. However, as a good rule of thumb, 2x 290X's in Crossfire, you should have at minimum a 1000W PSU. 3x goes up to around 1300W and 4x at 1600W necessary.

400W is the min required for the card as long as you are only going to run 1 and you have at least 1 6 pin pci supplementary power connector coming off the power supply. if there is no 6 pin pci supplementary power connector then the PSU is not compatible.

I have my whole system hooked up to a 750 watt PSU except for my second card, which is hooked up to my 500 watt PSU. So if you're putting both cards on the 750 watt PSU then you should be fine.

300 watts is insufficient for this card. I'd recommend a 500w of real power. Don't buy a cheap brand. The longevity and safety of your entire PC rests in the PSUs hand.

The card itself is rated by Nvidia to use about 155 watts. If your just running one you won't need to buy a real heavy power supply. the computer I built with this card calculated to use just under 400 watts overall (and I put a 4th gen i5, 8 gigs of ram, 2 hard drives, multiple fans, 2 DVD/blu ray roms, and a decent mobo) and I used a 500 watt psu. Just make sure your power supply has the proper connectors ( you will need an 8 pin and a 6 pin connector to power this card, careful not to confuse your 8 pin motherboard connector with your 8 pin video card connector.)

You should have no issue powering the R9 295 (running in crossfire with another 295 card). You might even consider a lower wattage PSU depending on what other items you're planning to add in the future.Reference: http://www.guru3d.com/articles-pages/amd-radeon-r9-295x2-review,12.html

yes, you must install a 1500w psu for both graphics card, then youll have a quadfire installation, so it requires more power, greetings and hace a nice day

This PSU should have no problem driving your system. The only way you would come remotely close to taxing the CX 500M with that setup is if you heavily overclock your CPU and GPU, and even then you should be just fine. As long as you do not plan to add a second graphics card, this PSU would be an excellent choice for you.
