I have a problem, i have found my old dell optiplex 755 desktop. I am planniong on installing a Core2quad Q6700 proccesor which fits my computing needs but i am in trouble with the graphics card. the one that came with my computer is a 280 watt psu. I did find a decent graphics card (Radeon hd 4890) this one also fits me for the games i want to play, the problem is that it requires 2 6 pin power connectors, the real problem is that there is none coming from my psu, or anywhere in my pc. Is there a good psu upgrade because it requires 400 or 500 watt psu. And if my current one works, is there any way on getting a 6 pin connector to poiwer the graphics card up? or is it worth getting a similar performance gpu without 6 pin power?
*edit* I just ran an online power supply calculator and i found out that i require a 468 or ower power supply
