A:Answer It's hard to say what power supply would work with this computer because the motherboard has a proprietary main connector and additional 4 pin connector. there are some adapters for the main connector, but I'm not sure about the additional 4 pin connector, It might be a ground, but I've had some trouble finding info on it. The included power supply does not have a pci-e connection, so if you are planning on installing a discrete graphics card, it will have to be one which doesn't require a pci-e connection.
