is there a way that I can check if it will support the full 75w or will i just have to try to see if it works?that PSU should be fine, however the board may not supply a full 75W for the card. some OEM boards are limited to 50Wor even lower 30W.
the 1650 is a 75W card and it will draw all the power it needs from the slot IF the slot provides 75W.
