Because, in case you haven't noticed, quite a number of people who post a problem about their computer or games crashing or having errors are using a complete garbage power supply which makes troubleshooting impossible and most of the time is the cause of their problem. And actually the 560 Ti has 3 versions, 2 with a TDP of 210w and one with 170w whereas the HD 7950 versions have a TDP of 200w and the boost edition with a TDP >225w. Now, let's assume he has the OEM version because he has a Dell, and let's assume it is a reference OEM version running at the specified clocks and voltages, so it draws 210w. Now, if he were to get a Boost edition with a greater power draw than his current card with a small, unknown power supply because the Dell website does not list the outputs, then would it work? Who knows, I wouldn't trust it. And who is to say Dell didn't fiddle around with the 560Ti to give it a lower power draw, perhaps closer to the base 560Ti with a 170w TDP, then even a base HD 7950 will draw a significantly higher amount of power.
There are to many unknowns, and I will not advise people that it's OK to spend a not insignificant amount of money, around $290, on a higher end graphics card, when they will be powering it with a small, unknown, built-to-a-price OEM power supply. You may feel comfortable with that and that's fine, and you may be right it and could handle it, but I'm not that confident it will and I'm not willing to say that he should risk more than just a graphics card when there are quality power supplies out there that would guarantee a 7950 would run without issues for years to come for around $50.

I just simply need to know which 7950 would benefit be best, and on the page of cards it has a list of power supplies suited for the card & motherboard, just not sure what one to get on that either
Amazon had more than one 7950 by Sapphire and I'm not too sure on the difference to be honest, I openly admit being a n00b
You can't go wrong with either Sapphire or HIS brands, IMO. They both have a good reputation. Each card can have a different set of connectors, ie DVI,HDMI,etc. Choose a card with the connections you need for your computer/monitor setup. A good power supply from a reputable company such as Corsair (and a few others) is a good investment for your computer and will in all cases be better than the OEM power supply which is chosen by the lowest price...as mentioned.

I'd say you're still tweaking these figures a bit more than is realistic. Dell is not in the business of creating microprocessors, so there's a limit to how much fiddling they could do, and if you compare OEM to factory overclocked cards, then of course power consumption is going to be different.
In general though, if you had said this from the start rather than "OMFG PSU MELTDOWN!", then you might have been free of my constant needling, for once.

I would go with Sapphire as well. The only two times I have strayed from them, an MSI 4850 was a pain, and this XFX 7970, which has been in RMA for almost 2 weeks after failing after 5 days of use, most of that time was under 2d load (ETA is Monday, or whenever FedEx delivers it, I hate FedEx). HIS seems to be another of the good brands, but Sapphire would be my first choice.
As far as power supplies go, you can't really go wrong with Corsair, but you might want to go ahead and go all out and get a top end 80 Plus Platinum unit from SeaSonic or Enermax unit in the 750w range. Yes it is overkill, but it will be something you will be able to use for a decade to come across several builds, the high capacity helping to ensure capacitor degeneration doesn't become a factor and to make sure if you ever step up to the very high end or have multiple cards you'll have the power to spare. But if that's not an option, a good 550w unit made by SeaSonic or Enermax (includes Corsair, Sapphire, and PC Power & Cooling) is what you should aim for, it's a good general capacity. 650w would be good as well as it'll be close to 50% load, but make sure you look over all the capacities, many times the higher capacity units will have good mail in rebates on them that'll put them close to or equal to the lower capacity units in terms of price.
I have an XFX 7950 Double D edition which I've turned up from 800mhz to 1100mhz. It runs like a champ and without issue's. Its also user friendly, you can mod it w/o loseing your warranty.
If you plan on getting a stock card, get a XFX Black edition or a sapphire Toxic factory OC'd editions.
Otherwise it doesn't really matter who you get after that. XFX has a lifetime warranty MSI /Asus is 3 years. Sapphire is two years , but if you have to RMA it you have to pay them 20$ to take advantage of it.
I appreciate all the advice everyone, I will consider buying a Corsair power supply, and now I know Sapphire is really good.
I probably should have said sooner that as of my Tower, I only use 1 monitor (HDMI), I don't have a bunch of stuff running in the background as I'm playing games with Steam or GFWL, I keep my PC clean & defragged, and always updated.
On Amazon I'm finding 2 versions of the Sapphire 7950, unless you recommend another site with more options.
