Unfortunately the video slot is short.12 inch long cards do not physically go in nor do 10 inch long cards.
I use a Radeon R7 250E.

With the upgraded PSU and R7 260X should be fine as long as its a short card.

The Aux power comes from PCI-E power connections on the upgraded 650W power supply. A plastic Ruler will tell you what does or does not fit. More than 8.5 inches is likely not working 10 to 12 inches does not physically go in. You can use a plastic Ruler to see this for yourself. 8.5 inches seems to be Max.

Short cards work fine. That means you can use Single Fan Cards.

Not really a specific Dell question, since no long cards will fit in my 3847, but I want to put a long one
in my Lenovo, don't have an 8+6 power cable, (or a 500W ps) do the modular power supplies like Corsair
come with
all the necessary cables? The ads only seem to show the motherboard connections.

What type/wattage power supply do I need for the 750 ti? The 3847 has a 300 W supply with no extra power connectors.

Technically the onboard 300W supply should work. However it would be requiring 100 percent capacity.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139061
EPS 12v 2.91 power supplies are required. Meaning that they have 170W on the 3.3v/5v Rail, 15 to 25W on the +5VSB rail and minimum 375W on the 12V rail.
Minimum recommended supply is Corsair CS750M based on these factors AND the Dimensions of the power supply.
CORSAIR CSM Series CS750M 750W
ATX12V v2.4 and EPS 2.92 80 PLUS GOLD
Certified Modular Active PFC Power Supply

It looks like the same thing but the price tells me its a fake NOT MADE BY CORSAIR product. There are other visual clues as to why they are fake but I'm not going to give that information away so that the counterfeit parts will Look more genuine.
http://www.corsair.com/en-us/enthusiast-series-modular-tx850m-80-plus-bronze-certified-750-watt-high-performance-modular-power-supply
That's also why corsair says on their site that they will not warranty Items that are labeled as corsair but not actually made by corsair.
http://www.corsair.com/en-us/support/warranty
Also excluded from this warranty are counterfeit products; that is, products that Corsair, at its sole discretion, determines were not manufactured by Corsair or any of its authorized manufacturing partners.
$50 is a (I AM FAKE BLOW UP YOUR MOTHERBOARD CATCH FIRE) price for this power supply.

CX750 is Different from TX750 or CS750M. Choosing a power supply on price and single watts alone leads to unhappiness and failure.
170W on the 3.3v/5v rails, 15 to 20W on the +5vsb and 375W minimum on the 12v rails is a requirement for proper operation of sandy bridge and haswell based systems. The 130W on the 3.3v/5v rails is under powered by 40W and the +5VSB is under powered 5W
Theres more than enough on the 12v rails at the expense of the others. If you get 750W on the 12v rails you have ZERO watts for everything else.
So no $90 is likely not fake. $50 or $65 absolutely is fake. As I Said I could see from the pictures that they were fake but I'm not going to get into why I could tell for a few Dollars more you get a MUCH Better Power supply in the TX750 or CS750M. The "Issue" with the CX750 is that it is NOT EPS12V 2.92 certified. Its also LOW LOW LOW END on the ATX scale which is why they don't say ATX 2.4.
http://www.corsair.com/en-us/cx750-80-plus-bronze-certified-power-supply
Note on the Label for the Dell that they provide 20W on the 5VSB.
If you add up all the currents its more than 305W but Dell does not overstate the total output of the supply.
5V @ 22A = 110W
5VSB @ 4A = 20W
3.3V @ 17A = 56.1 W
12V @ 36A = 432 W
-12 @ 1A = 12W
630.1 W Total on 305W power supply.
80 percent of 750 = 600W
80 percent of 550 = 440W
This means that 550W supplies for some dell models will not even turn on the machine due to lack of power in specific areas.
And no supply is 100 percent efficient.
This is why I recommend an EPS12v Corsair CS750M
DELL's 525W power supply Guarantees 150W on the 3.3v and 5v Rails. But also again Rates the 5VSB at 20W.
