Power Consumption

Total System Power Consumption
Tested at the Outlet

We used SeaSonic's Power Angel Power Meter to measure the amount of power our test system pulled from the wall. You'll find three figures below: power supply's maximum rated wattage, peak power consumption under a full CPU/GPU load, and how much the system pulled from the wall when idle, following a fresh system boot.

To get a sense of an absolute worst case scenario, we loaded up Prime95 and FurMark, a brutal combination that's even a little bit dangerous the way we run them, allowing the videocard to go full bore with reckless abandon. In doing so, the TouchSmart 520-1070 topped out at 130W, pretty well short of the power supply's maximum rating of 180W. It isn't a big PSU, but plenty enough to handle what's already a fairly well spec'd machine.

At idle, the TouchSmart system pulled 60W from wall, more than the ET2410 (42W), but acceptable for an all-in-one system powering a PC and monitor combined.
