Ok, I got a new graphics card for my PC. Turns out though that my PSU doesn't have enough power to run it properly. I want to upgrade my PSU. The problem is that I've heard that Dell computers use different PSUs than the standard ATX ones (ie. wired differently). I've also heard that there are some exceptions. I've looked at the PSU and it seems to be the exact same as a standard ATX one (dimensions) but I don't know about the wiring. Does anyone know anything about this?

No-one know anything about this?
