3 Things to Know About RAM Capacity and Power Consumption

RAM uses very little power Each DDR4 stick draws about 2-3 watts at idle and 5-7 watts under load. DDR5 is similar.

Upgrading from 16GB to 32GB adds minimal wattage Going from one stick to two, or from 2x8 to 2x16, adds roughly 3-5 watts total. That is like turning on a small LED bulb.

Power consumption should not factor into your decision Your CPU pulls 65-150 watts and your GPU pulls 150-400 watts. The RAM is a rounding error and will not show up on your electricity bill. Focus on speed and capacity instead.
