I have a xps gen 4 and I want to upgrade my graphics card (currently its an ati radeon x850) but i dont know what the power supply amps are. I know that its got a 450watts (it was the default power supply that came with the system) but nothing else can someone please help me. I need to know what the volts are, I presume 12v and the amps? Because its a xps gen 4 it means that I cant open the case and read it off the power supply unit because its got a green cover on it that wont come off.
I want to get a "BFG 8800 GTS" this is its internet link
You can't be sure that just any psu will work with a Dell. The pinout may be different. I've seen a few that were destroyed by new power supplies. I have no idea when or why Dell does this, but they do. Better ere on the side of caution, and buy one specifically for Dell. Besides, unless you have a bunch of hardware, the psu you have now will work fine.
