Dell power supply upgrade

[Newfiestang50]

Does anyone know a way to install a larger PSU in a Dell Studio desktop (purchased in 2009). I purchased a Corsair TX650 and I am told that this PSU will not work in my Dell, something about the cable pinout configuration on the connectors being different than what the Dell MB requires. I cant tell you much about the PC except that it has a Q8300 Quad core processor and it has 6 gig of ram. I did just install the GTX 660 with no issues but I am concerned that the stock PSU (350watt) will not run this card.

Not 100% sure but could it be a 540 or 540N, just going by my account on the dell website but its not clear what the model # is, just specifies its a Studio. I do see the number 540 used in other arears of the build slip on my account.

Yep, looks exactly like mine. As mentioned above I upgraded the power supply at time of ordering back in 2009 to a 350 watt unit. I just purchased a GTX 660 OC version along with a Corsair TX 650 but I am told the new PS will not work in my PC. The vidio card is installed and running fine however I never did any gaming yet.
