Hello, im looking to upgrade my dell inspiron 530's PSU. It currently has 2GB ram, Nvidia 240 GT, and an intel duo 3.2ghz. I want to upgrade my graphics card to a 7770. Will this PSU be compatible with this computer? I plan on buying a cheap one because of my low budget. All answers appreciated. Thank you!
