Tech Question of the Day (A+): Examine the figure. Of the devices shown in the Device Manager (expanded), which one will require the most power?
(See the answer and video response below.)
The GTX 970 video card will require the most power compared to the rest of the devices that are visible in the figure. The “GPU” will sometimes require more power even than the CPU. Network adapters, sound cards, and USB-connected devices pale in comparison when it comes to power usage. The important thing to take away from this is that you need to plan what power supply you will use very carefully. Be sure to estimate the power usage of all devices combined – taking into account potential future expansion – and then get a power supply rated at 1.5 times that amount, just to be safe.
