I am totally new to the world of desktop upgrades. I want to turn my Dell Inspirion 530 (~6 years old) into a machine that can run some decent games. It has an Intel Core 2 Quad Core processor (Q6600, 2.4ghz), 3gb DDR2 memory, 350watt PSU, & 2 hard drives (the oem 7200rpm 320gb & a WD Green 5200rpm 1.5tb). I decided to purchase a Corsair CX 430W modular PSU because it was on sale. It hasn't arrived yet, but I now worry that it may not work with my machine, because apparently some Dell's use different pin-outs. Is there anyway I can look at my machine and verify this? Also will this power supply be a safe bet with say an HD 6750 or HD7750 GPU?
