You're going to need;
A) 2 miles of No.00 wire.
B) SpreadNok cable clamps
C) A pair of Klines
D) 2 rolls of black plastic electrical tape
your Power Supply needs a 6-pin PCI Express power cable,http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress
Plug it into the Top/Back of the graphics card.http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5247878&CatId=7387
(I watched the video)
Your PCI-Express x16 slot can deliver up to 75 Watts of power.
The 6-pin PCI Express power cable, can deliver up to 75 Watts of power.
Minimum of a 400 Watt power supply is needed.
Looking back at the Playtool link, and the 6-pin PCI Express power cable;
Note the 6-pin PCI Express adapter power cable, shown on the right.
THIS, is what you use if your Power Supply, does NOT have a 6-pin PCI Express power cable.
TWO 4-pin Peripheral power cables plug into it.http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral
I say again...............TWO 4-pin Peripheral power cables plug into it.
DO NOT use just one.
I don't care, if that is all the 4-pin Peripheral power cables that were left.
If you use just one 4-pin Peripheral power cable, you will;
A) Burn the gold plated contact pins on the bottom of the graphics card.
B) Burn the contact pins down in the bottom of the PCI-Express x16 slot.
C) Burn the plug connector end on the 6-pin PCI Express adapter power cable.
D) Burn the contact pins on the graphics card, that the 6-pin PCI Express power cable plugs onto.
Happen right away?
Down the road a little after you have forgotten all about it.

Wow, my monitor screen just went blank."

"Nvidia GeForce GTX650 graphics card buried today, along with a motherboard.
Owner cited for neglect, pain and suffering.
Plea bargained to do better in the future" )
Not having a 6-pin PCI Express power cable on your Power Supply, suggests it is a low quality unit, and is underpowered for that graphics card.
Want to burn up a graphics card, just under power it.
[ 4-pin Peripheral power cable;
Also misnomered as a 'Molex' power cable.
Molex was the first company to produce that design of power cable CONNECTOR.
(I don't think they designed it, just manufactured it; if memory serves)
Name stuck. Kinda' of like calling an open-end wrench a 'Crescent wrench' ]
