Is a 750W PSU good for this card or should i go higher??

Depends on what the total system requirement is. 750W is fine for most requirements, way more than needed for most requirements.

Yes i have a 750W PSU and it should be even enough for a crossfire with two of these GPUs

It's good enough nut I w Po us recommend higher as a couple of times I have lost video which I believe is due to my 750 not quite holding it's own.

I have 700 watt in mine and it works just fine as long as you don't want to over clock I am running a amd phenom 2 965 black edition running at std clock of 3.4 GHz when I tried to over clock is only time I had power issues with that card..

Depending on the processor he's using, you should be fine with a 500W PS. If you see him upgrading further down the road, you may want to consider higher. It will save you some money overall. I run this card and an i7 processor on a 510W PS and it is perfect. north of that wattage and you open it up for upgrading down the road, which is definitely a good thing. In conclusion, 500W+ PS and you will be fine for this card. :)

ud better use a power supply more than 800w. I use a corsair 1000w supply for 4790k and this card.

No, I would recommend at least a high efficiency 450 or 500 Watt, it may power up but you can damage the card with not providing it enough power or damage your mother board. You may find some calculator that says other wise but I wouldn't risk it. (I burned up this same card and ruined my mother board pcie slot, not for running to little power but my power supply shorted giving unstable power, to little power would be unstable.

You always want more power than what is suggested. It will run but will put extra wear in the 600w power supply. Took a fast look if you are spending this much on the graphics card take a look for yourself. You can find a decent 850w-1200w for under $300. I did see one under $100, when you can you want to double the power requirements.

I have a 300w PSU as well as this card installed, 2 HDD (2TB+320GB), i7 4770 CPU.. (prebuilt Acer) For a few months everything worked fine and now I constantly get BSOD's, ticking hard drives and random restarts. Would definitely recommend at least a 450w or greater PSU. Spend $45 more and get a gtx 750 ti, its better and requires less power than the gt640.

As far as the overall watts are concerned, this is enough. There's also enough plugs for all of that (with room for another graphics card or two if you wanted more later). You should be just fine! I love this PSU. Highly recommended.

you should be fine as long as you arent planning on running a super high end graphics card with it because 500w might be a little bit low for some of the major graphics cards. but if you're just gonna run something like a 6850 or something you should be just fine. hope this helps

Personally, I like to have a little more than required so i would go with an 850W PSU, so to answer your question, yes this one will work fine. You could also use a 750W PSU as well though.

You will have to upgrade you PSU to at least 400w for to run some games, I would recommend a 600w or above. I have a corsair tx650 and it runs cool even with a lot of power demand.

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.

I found the wattage was not as important as the amps on the 12V rail. This card needs two 8-pin (or 6+2 pin) connectors, and my older 850 watt PSU ultimately did not have the right amps to support the card. (System kept shutting off... card had blown out the PSU.) 650 watts should be fine as long as your two 6+2 pin connectors off the 12V rail can support at least 20 amps each.

This would be a great card but you might want to go to a power supply calculator to see if you psu can handle this card and everything else you have.

I would get at least a 450 W PSU... preferably 600 W. I was running into issues with a 450 W, but upgrading to 650 solved all my issues.

You could run this on a 150w power supply as long as it wasn't garbage. It has no external power requirements, so the most it could possibly draw is 75w. This card won't even come close to that. The recommended 350w is extreme overkill because some people have extremely low quality PSU's that come with cases.

This is a Higher end graphics card you probably want at least a 750 watt PS, just to be safe especially if you have a decent CPU/Ram and Cooling system in your rig.

One of these draws 250 W according to Nvidia so x2 = 500. You also need to account for your CPU MoBo and other things so I would go for something ratted with 700+ watts.I recomend this SilverStone ATX12V/EPS12V 750W Silver PFC Power Supply ST75F-P (Black) or this if you want silence http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087
