The XFX HD-489A-ZDFC Radeon HD 4890 Video Card specifications state that it needs at least a 500 Watt power supply. The XCLIO STABLEPOWER 500 Watt Power supply should be enough, but if I were you I would look around at a power supply that puts out a little more (at least 550 Watts). The reason for this is the components will put less of a load on the power supply and give it a longer life.
