Dell XPS 27 Touch All-in-One Review

Power Consumption & Noise

We used a power meter to measure the amount of power our test system pulled from the wall outlet. 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.

The power supply rating on the Dell XPS 27 Touch is 260W, and it it needs almost all of that headroom while suffering through a full load of Prime 95 and Furmark torturing the CPU and GPU. At idle, the system pulls a respectable 87W.

This system is remarkably quiet; it’s easy to forget that there are serious components in there like discrete graphics. The only time we heard anything above a whisper from this rig is when it was churning through certain tests such as the SANDRA Processor Multimedia test and Aliens vs. Predator Under stress the system uttered a low whirring sound. It was a little odd because we didn’t hear the same noise during the Prime 95/Furmark test.  The extra sound isn’t much, but to sensitive gamer ears it could be noticeable.
