I have a Dell Inspiron D530 350 W power supply. I have just purchased a XFX 4770 video card. Does this computer have the required P8 connector? Is that a cable coming out of the powersupply? I have looked and nothing is apparent. Do I have to upgrade my powersupply?

Is this the cable you are referring to? If your PSU don't have it (and I doubt it do) then you can buy one of these.
