[i]There has been incompatibility issue between the SmartPower2.0 and less popular motherboards like ECS, Asrock, Jetway, Epox. That power supply should work fine with Gigabyte, ASUS, Intel, Abit. We do have a revised version of the SmartPower2.0 power supply that will work fine with these motherboards. If you'd like I can forward this information to our Europe office to get your power supply replaced with this new revised version. Please let us know. By the way what is the serial number on the power supply?[/i]
