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.
Being a factory overclocked model, the MSI Gaming X will draw slightly more power than a reference-clocked GTX 1660 Ti – probably in the region of 10W or so. Even then, power consumption is still not high – just 4W more at the wall than GTX 1060, which clearly shows very impressive power efficiency given how much faster this card is compared to GTX 1060. It will be interesting to analyse a reference-clocked 1660 Ti to see how fast one of those cards would run out of the box, and how much power it would draw.
