Can I use this card with core i5 3570(no K) on a machine with 400W power?

The recommended minimum is 450w. However, my machine only uses a 192w when I'm using my my GPU at 100% on a i5 3570K. I think it will work fine on a 400w, but continuous use at 100% GPU may lead to a short life of your power supply.

The power target of the GTX 660 is only 115W compared to its TDP of 140W (and reviews seem to show it running closer to that 115W). You should be fine adding it to your system, assuming you don't have 10 HDDs in there as well.

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

No do not run this card on a stock PSU. You also want a new CPU your Athlon isn't even close to having enough power to keep up with this card.

No, I wouldn't recommend you use this card with such low PSU. If you can't upgrade your power supply I would go with a 7750 instead. It would be better if you upgraded the power supply and buy a better card than either though.

Yes, currently I'm running mine with a corsair 480W builder series. For the most part the GPU is low power and runs directly off the motherboard.

no it's not. You need at least 550W to get the full potential of this card.

You shouldn't, but it depends on what else is on your machine. I have 3 hard drives and added this card, which only uses 110 watts, and it's working fine with a 500w PS. That's one reason I selected this card because of it's low power consumption.

Almost definitely. I was running it on a 500w PSU but I also have a lower power consumption from my CPU to help with that. Unless you are running it with a AMD 9590 or something like that, 650w PSU should work great.

Should work fine, card is fairly small and does not need more than like a 450w ps.

You can do either. But this card requires both available power adapters so take note that power consumption will be high with this card and higher running both

You may not even need a bigger power supply. It would be worth it to try without changing your power supply first. I'm running an i7 3930k, 32 gb ram, and two of these cards on only a 750 watt... Depending on the wattage if your stock power supply you should be okay!

I have this card running with an amd A10-6800k apu on a 430 watt Corsair CX 430 power supply. It's rated at 32 amps 12v, and I'd consider that the bare minimum.Just do the math, 32 amps * 12v is 384 watts. This card draws 150 watts under load, leaving me with a little over 200 watts for the CPU and other devices. So my setup is fine, but if you have a higher end i7 or AMD FX CPU, you'd need a bigger power supply.

It depends on how many other things you have in your system, but 850w should be more than enough. I'm running my card on a 550 W PSU right now. As long as you have the needed power connections off your psu you are golden.

I am using 400W power supply with this card and it works just fine. This card has pretty low power requirement especially since it has no cooling fans. This card is designed to be fully fanless by using bigger heat sinks. I mainly used it for the good performance, smaller profile and fanless design. Please let me know if you have further questions.

400 would be pushing it. I have a 600w and it does fine. I would say the minimum would be 500w but it really depends on your total power consumption system wide.

Truth be told the manufacturer recommends a 400W power supply which seems like a very high wattage requirement? Since they cannot be sure of your system configuration they have to err towards caution to ensure that you have adequate power to drive the card! Here is one of the best calculators I have used to check power consumption resource needs . . .http://www.thermaltake.outervision.com/

It's a 19W card. Unless you're running an Intel Extreme edition CPU or an 8-core AMD CPU, you'll be well under the power limit for your power supply.
