I wanna ask a question.My psu which is a cooler master 430w doesn't have what we call that cable that connects to a graphics card which i heard.So if just say i want to upgrade my gc which needs the cable,must i buy a new psu or is there any cable which could be bought and just simply added to the wires so that i could connect it to the gc?

Oh ic phew i thought i'll need to change my psu.So my psu already has the cable which connects to the gc right?If it doesn't include in th e box can i buy it?

Anyone can help me.I just used a PSU calculator which says that the max wattage my psu consumes is 389w and I am using a 430w PSU.Will I experience any problems if I were to continue using my CM 430W PSU?

So if I were to upgrade my gc just say X1950XT I would need a new PSU too?
