i have a dell dimension 4700 the old psu utilizes a 4 pin cpu MB connector i recently aquired a corsair cx430 psu only it has a 6 pin (NOT a 6+2) are the pinouts the same, could i just plug that in or would i need an adapter, or does that not seem feasible at all?

Its easy to mix these up because they are basically the the same thing.

The 6 pin power connector is the PCI-e power connector, it has 3 12volt leads(yellow) and 3 grounds (black).

The PSU must have a 4 or 4+4 pin CPU connector. This connector has 4 12volt leads(yellow) and 4 grounds (black). The connector looks the same but the shape of the keying on the pins is different so it wont fit.
