I am in a plan of buying a graphic card.
My concerned cards are:
1.HD 7850
2.r7 260x
3.r7 250x
4.gtx 650
5.gtx 650ti
6.gtx 750
7.gtx 750ti

My PC Specs are:
ASUS M5A78L-M LX PLUS Motherboard
AMD Athlon XII 270
2x4GB DDR3 RAM
500GB HDD
ZEBRONICS 450w PSU.(NO 6 pin pci power supply slot for graphic card)

My Question is does it really need 6 pin power supply for the AMD cards as my specs entirely take a maximum of 150w??

Some are saying some of above notified gtx series also need a 6 pin power supply.Is it true???

Can't we operate a graphic card with a 6 pin power slot without using it??
 
Solution
you'll need to connect it but some/many cards will include an adapter to go from your traditional 4-pin "Molex" power plug to the card's 6-pin power plug. if it's not included, buy one on eBay for a dollar or two.
