Can my computer handle this?

[norkss59]

i bough it years ago but never used it, it's brand new. Maybe i can give it a try if i can find a software that tells me exactly the watts of it?

The XW4400 should come with a 460W PSU as standard, according to HP's website, but they could well be wrong or your PSU may have been changed at some point.
Either way, even a 400W PSU (of good quality) would be adequate for that system, even after adding the GT740.  The 740 has a maximum power draw of approx 65W, even if it maxed out the PCI-E spec of 75W (cards without an auxiliary power connector cannot draw more power than this unless something goes horribly wrong which will kill the card and motherboard) you'd be perfectly safe with a 400W PSU.

Thanks Calum for assisting with this one. Btw, I looked all over for a watt rating for the GT 740 and didnt find any info to help him with this. My assumption was that if it doesnt have the 12 volt molex connections available then its likely less than or equal to 75 watts.

 Is there a specific website you use that shows all cards and wattages etc?

[Calum]

Any PCI-E card with no auxiliary power connectors may only draw a maximum of 75W as more than this would violate the PCI-Express specification, so that is a safe assumption.
In this instance I found the power consumption rated at 64W on the Nvidia website - http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gt-740/specifications
While not all cards will be reference design and thus identical, with a low end card like this it's pretty safe to assume differences between models will be negligible.  Even on higher-end cards, unless there's some major design changes (some top-end cards with factory overclocks and other tweaks may even use different power connectors from reference design to facilitate this and thus may draw a decent amount more power than standard but this isn't that common) then the "reference" power consumption numbers should be close enough for estimation.

More broadly, if the figures aren't on the manufacturer's website, almost all reputable review websites will have a section for any GPUs they review for power draw - this is often the total system wattage but again, by checking the numbers at idle vs load and any other information on there plus maybe cross referencing if unsure, this should give you a "close enough" estimation of a card's potential power consumption.  Most requirements listed on card manufacturers' websites or on boxes aren't any good, even if it's not wattage but instead amperage they often seem to quote them at random.  They're OK as a very general guideline but fail to mention important things like the quality of the PSU, which admittedly is harder to fit on the side of a graphics card box.

Alright so i installed the graphic card and it work just fine ! Thanks a lot to you two guys.In the hope to talk again in a near futur

Glad to help     btw are you able to run Ultra settings now with World of Warcraft with good frame rate above 25 fps with that card?

Here's a sidebar for you Dave
Quebec is a unique case with regards to Canada because even though they are a part of Canada they want to preserve their French heritage/history. Considering that historically it is effectively a French Colony that was taken over by the British and basically surrounded by Anglophones one can almost understand the particular brand of intolerance that is sometimes shown in those sorts of culture-oriented laws that Quebec has/had. It is also worth noting that it is quite possible for somebody to not know English at all very well in Quebec, so a refusal to speak English may be an inability. One might argue, "well, they should learn English" which is silly given that most Canadian's, particularly in the western provinces, don't know French.

There was actually a time- I forget when and can't be bothered to look it up- When Quebec as a province enacted the "notwithstanding clause" which basically allows a province to suspend one of the rights given in the charter of rights and freedoms. In this case, they did so to effectively discard the requirement of having both French and English, and they legislated laws that actually made it illegal, as I recall, to have shops and other businesses have any English translations. I forget the extent it went to but it got pretty crazy at the time. There was also some terrorism in the form of political abductions and murders in the 60s, though the FLQ was in large part about socialism/leninism insomuch as French-Canadian independence.

It is worth taking into consideration that when it comes to French Canada there are many who feel so strongly about preserving their french heritage and effectively shutting out the rest of Canada that we've also had a few referendums as well as some terrorism(Up to and including political kidnapping and murder). So there are definitely some very strong feelings in that regard and as mentioned, given the history one can understand why that is, (even if one should not tolerate the methods used!), even if the rest of Canada typically doesn't.

I'm too stupid to understand this...

 Should have got the 750 as it is the only 700 series with the new low power chip . My son has the 750 ti 2gb from evga that is powered by the motherboard and it is on a intel q35 mb , 3gb ddr2 , core2duo 8500 , generic 500w ps { I'm sure your specs would run it  , slight bottleneck in your cpu but likely never notice } Awesome video card , runs Skyrim on high 55+ fps , always runs cool and benchmarks better than my gtx 275 .

Glad to help     btw are you able to run Ultra settings now with World of Warcraft with good frame rate above 25 fps with that card?

Yes i can run Cataclysm without any problems at ultra, skyrim ultra settings with almost 60 fps and all the games i own at ultra.
I personally had to modify the computer case to make it fit which implied me to cut a metal bars. But yet, it worked fine so far, no power cutting or anything!
