HP Z1 27-inch AIO Workstation Review

Most users shopping for a single system, may not consider power consumption when making a purchase, but admins looking to acquire many systems will certainly be interested in this data. We placed a power meter at the electrical outlet to catch the Z1’s power consumption at idle and while under a heavy load. To create the load state, we ran Prime 95 and Furmark simultaneously to whack both the CPU and GPU.

Power Consumption
Real-Use Testing


The Z1's power supply is rated to handle 400W, and HP assures us that the PSU supports all of the configurations it offers – easily. That seems to be in evidence here, as the system pushed only 213W at peak.

As for noise, the system is whisper quiet under load. When idle and even when doing basic tasks, the system’s sound never rose above our lab’s hushed environmental noise.

Josh cut his teeth (and hands) on his first PC upgrade in 2000 and was instantly hooked on all things tech. He took a degree in English and tech writing with him to Computer Power User Magazine and spent years reviewing high-end workstations and gaming systems, processors, motherboards, memory and video cards. His enthusiasm for PC hardware also made him a natural fit for covering the burgeoning modding community, and he wrote CPU’s “Mad Reader Mod” cover stories from the series’ inception until becoming the publication editor for Smart Computing Magazine.  A few years ago, he returned to his first love, reviewing smoking-hot PCs and components, for HotHardware. When he’s not agonizing over benchmark scores, Josh is either running (very slowly) or spending time with family.
