Are you looking for a super cheap power supply? What are you going to be using it for? Coolmax is powmax, which makes ****ty things and has bad customer support. If you are using that power supply for a low end computer that needs only 200 watt of power, then that would be fine. However, if you really need the 450 watts of power, I would suggest looking into forton or xcilo power supplys as they are known to provide good power for cheap.
