a95f x1

Expl0dingBanana was kind enough to post a quick test with wall meter to determine current draw in this post. A summary of it is below:

• A95xf1 Power Draw @ 120v:
  • Startup: 4.8w, 0.96A
  • PoGo: 4.2w, 0.84A

Isdor did some testing on 2x a95x f1, with one running raids and one mon_mitm, in the post. The pair pulled 1.4 amps at a voltage of 5.1v.

Tannix tx9s

Expl0dingBanana did further tests on tx9s in this post. Yielded the following information:

• Tx9s @ 120v
  • startup: 6.9W
  • running: 5.5 - 6.5W
  • Peaks: 7.5W

JabLuszko did a quick test on a tx9s utilizing a USB power meter in the post, showing it used 0.95A @ 4.9v.

Sizing a power supply

As seen in the above data, startup current draw is higher than power draw once the device is running. Assuming that these cheap chinese power bricks are not 100% efficiency, it is safe to say that the devices themselves pull less than 1amp.

When picking your power solutions, whether it be usb or power supply, leave yourself some headroom. Don't buy a power supply with a 40a rating, put 40 ATVs on it, power them all on at once and wonder why things aren't running as expected. Pick a power supply that can feed all your devices assuming they boot at the same time, as that is the worst case scenario. Feel free to go cheap and do what you want, but for the 40 atv setup, just go with a 50 amp power supply.
