A desktop psu powering a LCd monitor? how does that work?
well the graphics card uses minimum 38watts and must go to 50-60 under stress, so what are your system specs?
A System in idle
Core i7 965 / X58 based and overclocked to 3.75 GHz.
with that graphics card at full load. = 196W
so i think you are ok, just not sure about this LCD powered monitor, are you sure it is being powered by the psu? isn't just the outlet (extension of the energy) that some psus have? if yes it is nothing more than a extension they did this to turn of the screen with the psu no power is wasted from the psu if i'm not mistaken.
if the psu is not something generic you will be ok, but if you are using a generic psu with time will start to show problems.
