Can You Please Tell Me What The PSU Requirement Is ?? Just Got One Today, Went To Install, And It Said PSU Required Was 500 Watt, I Have 450 Watt Will This Cause An Unstable System Prone To A Shutdown ?? Thanx A LOT !!

It depends on what your system power draw is. Would need to know the rest of the components. The XFX 7770 draws about 80 watts under full load which is why it requires a 6 pin PCI-E power cable.

I think you might be pushing it with a 400W PSU. I guess it depends on the item quality. You may be just fine. Not really an answer, sorry.

Mine is in a Dell that had a 300w that went bad. I replaced with a 600w and have had no issues. When I did research before I bought the card, the suggestions that I read were a 400-500w psu

I have no clue. I have a 430W in mine and I don't have problems.. I can't see it taking that much.

you will be perfectly fine i have a 430 watt psu currently and i never even get near t going over that. this graphics card uses only about 80 watts on average. The only time you need to worry about wattage is when you get higher end cards or more of them.

Too late for you know obviously being a month later after question but in case anyone reads this deciding as well. Irregardless of the wattage, you need 30 amps or more. If you get a psu with a solid single rail all you need is 30 because all these video cards give an estimate assuming the amps are spread out on 2 or more separate 12v rails. The guy with the SFX 450W is actually more than enough because it contains a single rail with 36 amps. Don't listen to the people who say you need 650 amps, that's ridiculous unless you plan on doing sli.

Hi Luis. There's no extra power plug for this card, so that part is fine for you. But only 300W is pretty low. You can try it, and if you experience random shutdowns and instability, that's your primary cause and you should upgrade the PS to 600W or so. Obviously, no video card will really use 200W (it would simply melt down), but most PS are 80% efficient, a hard drive takes some more, the CPU takes some, on and on. As you can read, some folks are using it with 300W just fine. You need to take into account how much other stuff you have plugged in and running. I had five hard drives, a 125W CPU and so on, so it was unworkable to have just 300W. Hi Luis. There's no extra power plug for this card, so that part is fine for you. But only 300W is pretty low.

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!

I would try and do some more research on it and maybe give the company a call I'm sure they could give you a definite answer before making the purchase. But the lights in the psu are a nice touch and look great in my case. Hope I've been of some help.

I am using the antec 550 watt power supply which is working well for me with the am2 processor 2.6 ghz. I had another system with a 350 watt that seemed to run a little noisy. I don't know the minimum requirement but if have had enough power supply failures to know not to the minimum out. Sometimes the power supply manufacturer fudges the numbers. At least that was true in the past. Since this is for my company I opt on the safe side.

I have only installed to 500 watts or more. Probably not enough power from PSU!

Late answer, so I hope that you haven't had any problems. At full load, this card can consume up to 350W. I wouldn't go less than 750 for a PSU. If you plan on an OC, I'd go even higher. That being said, my CPU, GPU, and RAM are all OC'd. I've also got four HDD and one SSD, five case fans, and a 1050W Corsair. If you're considering spending this kind of money, I'd feel better knowing that the PSU voltage isn't going off course due to an overload, or that the PSU killed itself without taking casualties (fingers crossed).

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

Hi. I wouldn't try it with less than 500W. Obviously it doesn't consume that much, but if you're thinking of upgrading to this card, you probably have a couple hard drives, a higher-performance CPU and so on, and would need that much for other reasons. I had a 400W PS that was unable to power my system a few years ago, resulting in BSODs and random freezes, so I changed that out for my current 600W supply, which does just fine. I have an 8-core CPU, this video card, an SSD and four hard drives. I just had a look at EVGA's specsheet about this, and it says minimum 350W PS. I would imagine that is in a minimal system with nothing else hooked up. If you have any plans to upgrade anything in the future, being stuck with a tiny power supply will limit your options. I'd say start your search at 500W and if you find a good manufacturer of a more powerful one that's reasonably priced, get it.

I looked up that build and I don't know that the power supply is beefy enough, 250 or 300w is the size I found for it. 400w is the minimum for this card I believe. (mine is 450w and I have had no issues with the card at all.) I can't recommend it for you on that computer, because it would likely cause issues for you. Sorry. :/

Im never a 100% So I always use PSU calculators and find out my systems watt consumption. But as far as connections, it should work as this is a fully modular PSU. You can Google PSU calculators to help you guess how much you'll need. I always go a little over what they suggest incase you want to add stuff later and to be safe in case there is any fluctuation in power

I wouldn't recommend using a 435w PS. I would at least go with 600 watts as long as it is 80+ gold. This card does sip quite a bit of power.
