HP Touchsmart 520 All-in-One PC Review
 |
|
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.
