can't really tell .All depends on how your pc is configured. I personally used a 650w

If it is a good PSU like a Corsair, Seasonic or an Antec you will likely be fine. With a cheap PSU it will likely shut down your computer periodically at best and instantaneously at worst.

Combining the power needed from this card and your other components such as the CPU and everything else, your power supply will sometimes not be able to provide enough wattage and the computer will shut down by itself when it detects power shortage.

I don't see a problem with that. Though it might pose an issue if you have a lot of extra components drawing power i.e., several hard drives or really beefy fans.

You need to upgrade to 500. My PSU was only 300 W and I upgraded to a 500 W Corsair unit. The PSUs aren't that expensive. I didn't want to take the chance. Haven't had any problems.

Make sure that you listen for buzzing noises which might mean that the card is pulling too much power. It should work fine with a 300 to 350w power supply but the recommended wattage is 450w.

Would recommend at least a 600wat psu.(Also depending on what else you have in your system)

That depends a lot on the other hardware in your system. It only draws 55 watts, so it shouldn't be too much of a problem, but I can't say definitively without more information.

My bet is still a power issue. While it came with the upgraded power supply I'll bet they also added upgraded the video card. When I ordered mine I also ordered a 700w power supply.

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 suggest you buy a converter which supports power at least 3 times larger than what you really need, this will make you less trouble. Thus for your PS, 500W seems good enough.

If you are going to go with 500w or 450w, make sure it is a high grade power supply, and not a cheap off-brand model

You should be OK. I just built a steam machine with a 430w PSU and I'm running this card just fine!

I seriously doubt you are using anywhere near your power supplies rated maximum. I have a 1000 watt PS connect to this UPS. Normally, it draws less then 300 watts. Even gaming, I've rarely seen it over 500.

Yes, You are safe. Because this power supply unit will not drawn power more than 550 watts. You also have to check other electrical components such as speakers, LCD display monitor and printer because these devices will need power also.

It would really depend on everything else in your system. If everything else pulls to much power, and there isn't enough for the video card, it will not preform as well and your power supply will wear out very quickly. I know from experience that too small of a power supply will burn out and need to be replaced. I would recommend at least a 500w.

I believe the minimum power supply is 500W. I use a 550W and haven't had any problems.

Yes. I am running it just fine off a 650W PS. Make sure its a decent quality Power supply though.

Provided there is an open pci slot on the pc (which you can find out by opening it up) and the psu is putting out 400 - 500 watts you should be fine. Upgrading stock PC's can be tricky though, I wouldn't recommend it personally, hard to get it to the standard you want.

Its a 500 watt power supply you could probably google it. It shouldnt have much effect espically if you are already running a desktop.
