HX 850 and HX 1050 is of same design, only difference is output as far as I know. So maybe it would be better to say be careful with the Corsair HX series.
Bitcoinorama, if I understand you correctly the issue only occurs after the ATX has shut down autoamtically.
When you then restart them they will do something odd, (i.e Voltage spike or something, Current surge seems odd as this would be an err on the Jupiter side).
this odd thing they are doing are frying the caps (Voltage spike => current surge) ore somethin.
This is exactly how our board was fried.
ATX shut down due to overload (

?)
When restarted... boom, smokes and fireworks.
did I get you right?
Precisely, that's what the GE guy stated. He said they surge for 30 seconds after reset, but after such time they are ok to switch off and on again, but by that time if your boards are connected, pop.
