We measure system-wide power draw from the wall while the card is sat idling at the Windows 10 desktop for 30 minutes. A reading under load comes from running the 3DMark Fire Strike Ultra stress test 20 times.
As expected considering this is a 1650 with no additional power connector, we saw the Palit StormX draw the least power of any card on test. It draws about 10W less than the Gigabyte 1650, too, which is to be expected considering that card is clocked higher.
