What type of power source does dell inspiron 531s take

[chris4393]

Hello,
I am thinking about buying a used Dell computer It is a Dell Inspiron 531S but it has no powersource so I need to know which one I should get and also can I upgrade the system to windows 7 if it allows.

The Inspiron 531S is a slim case and that's why the S after the 531 so with a slim case you have to get a TFX power supply. The power supply tahat comes with the computer is a 250w psu and the link above is for the Dell support page that has the replacement power supply that goes with that case. You can also upgrade that power supply to a 300w or 350w if need be.

You should also be able to upgrade to Windows 7 , I don't see any reason why you can't.
