will asus gtx 750 ti be able to run without a 6 pin power connector? and if I buy this card can my pc handle it?
My pc spec :
Core I5 3.2 ghz
8gb ram
Asus PB875 motherboard
450W PSU
btw I do not mean to overclock it...so will it run without adapter?
No, if it has a power connector it needs to be connected, otherwise it won't work even though it could technically take all it's power from the motherboard.
