what do you mean it keeps on restarting? Does it just not boot at all? Does it give you a beep code? Does it start windows and then restart randomly? I have never run a power supply less than 400watts since 2002...but no idea what the wattage requirement is for thse. Check out newegg's psu calculator to ensure it is enough. May be as simple as a driver rollback...no idea what exactly the problem is ur havin thou.
