I have a 3 monitor setup, what is the minimum power supply I need to run two of these cards? I'm running a 400W supply and the machine won't boot.

You need To add up ALL your power needs. CPU,MEMORY,MOTHERBOARD,CD/DVD USB ETC.....Then do a 1.5 times that number. Never run your power at max. Hope this helps. Under powering blows things. Buy a UPS backup to protect the whole package. Should have at least 10 minutes of run time. I know it hurts but in the long run it saves money. Still have a 486 running &#128516;

I paired this card with a 400 watt power supply, and that's about as low as power supplies go. So I'd say you're safe with at least 400 watts.

I couldn't get mine to work. In theory, you'd need 2. You also need a power supply for each.

This would depend on all the other hardware power requirements. Looking at the specifications on the card shows that it needs 600 Watt Power Supply, with a total power draw of 250 Watts. If you added second card, you would need another 250 Watts which would be 850 Watts. I am not an electrician but it looks like that may be a close call. However, required/suggested is often over engineered. If you can afford two of these cards, you likely can afford to buy a larger power supply if it doesn't. Why would you need two?

I'm using this guy: SeaSonic Platinum PLATINUM-860 ; SS-860XP2 Power SupplyThis GPU needs two dedicated power lines from the Power Supply to the GPU - if you try to split a single line it will NOT turn on. I used the power supply above to run a set-up with two of these GPUs

This graphics card manufacturers specifications call for a minimum power supply of 500 Watts. In the real world I would suspect that if you have a quality power supply of at least 350 Watts it would probably work. That being said, a 350 - 450 Watt power supply may fail at anytime or prematurely. Additionally, no secondary power connector is required...just the PCI Express slot on your motherboard. Good Luck

It may run on a 425W PSU but it will run sluggish. Yes the card requires you have two 6-pin connectors hooked to it to run properly. It will run properly if you upgrade the power supply. The card requires a minimum of 500 Watts, but my suggestion would be to go to a 550w at least or a 600w PSU.

I actually have 3 of these cards plugged into my Motherboard - I'm running 6 monitors without issue.

I just purchased this card and it requires a minimum 300 Watt PS with a minimum of 20A on the 12 volt rail. This is based on a newer core-i7 processor. I have an older core-i7 and my card seems to be working ok with 18A on my 12 v rail. I am only running One monitor at the moment, but I will have to watch during heavy gaming if my PC crashed or reboots. If It does than I will need to update my Power supply.

This graphics card requires a minimum 350Watts ... I have it with a 600 watt generic psu and pci express x16 1.0 port and works perfect.

Your power supply is more than enough for this card. 300 watts is the minimum requirement, you have 350 watts so you are good to go, my friend.

300 W power supply is enough to run this card. There are no separate power supply cord or connection is necessary.

I don't know what your entire system power requirements, but unless you have a ton of extra equipment running you should be fine with 750 watts. I'm running that gpu with a 650 Watt power supply and have zero problems.

I would search on Google " how can I use 4 monitors" Also call or email www.evga.com and ask them. I think one card can run 2 monitors even though is has 3 connections. HDMI, DVI and VGA. I'm not smart enough to answer that question. Sorry, Bob

The power needed for the CPU should also be considered. I read somewhere that MSI recommended 500 watts for a system with 1 card. Since you are overclocking the CPU?, and the GPU?, I would recommend a 850 watt PSU at a minimum just to be safe and avoid power issues. Have fun!

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.

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.
