  We have de­vel­oped and man­u­fac­tured CW 1.2 MW high power wa­ter-load for the use of the Super KEKB, an elec­tron – positron dou­ble-ring col­lider at KEK. The tank and rf win­dow of the wa­ter-load is the cir­cu­lar and cylin­dri­cal-type. The ma­te­r­ial to ab­sorb the rf power is a tap water. This load is equipped on the 3rd port of the cir­cu­la­tors to safe the 1.2 MW CW kly­strons to drive the ARES cav­i­ties in main ring. The op­er­a­tional fre­quency is 508.9 MHz. A proto-type model of this wa­ter-load was fab­ri­cated at Sep 2012, and tested using by high power kly­stron (1 MW) at Oct 2012 at KEK D2-ET sta­tion. The re­sult of high power test will be re­ported in this paper.
